fbbcacff7d board/qemu/sh4*: Remove linux-headers patch
Previous patch about time data structures [1] provided a dirty fix
that did not solve the real issue.

After discussing with Linux folks on the SuperH mailing list [2],
the patch was deemed unnecessary, as the problem lied in uclibc.

370e663593 configs/qemu_ppc_virtex_ml507: remove defconfig
Support for this board was removed in Linux upstream [1] since Xilinx
new design tools dropped these platforms in 2013, along with all
PPC405/PPC440 new designs. They are not maintained nor tested anymore.

742f37de8d configs/qemu_*: bump kernel version to 5.10.7
Bump most QEMU defconfigs (every one that was previously on 5.4.y)
to latest longterm kernel 5.10.7.

Please note the following exceptions/modifications:
- board/qemu/qemu_s390x_defconfig: ignored (already up to date)
- board/qemu/sh4*-r2d:
    - Remove the remaining kernel patch [1] provided by Alan Modra
      fixing rodata alignment, carried here by Romain Naour [2] to
      fix an issue preventing kernel from booting with binutils 2.23.
      Patch is present in upstream Linux now.
    - Fix compile-time error regarding 64-bit time data structures
      from kernel headers when building with uclibc. Previous fix [3]
      existed upstream; but see details below.
    - board/qemu/ppc-mpc8544ds: Updated kernel patch
- board/qemu/arm-versatile: Updated kernel patch
- board/qemu/mips*r6*: Updated kernel patch

Tested on all configs/qemu* configurations. [4]

f609afb7e8 configs/qemu_*: bump kernel version to 5.4.88
Bump QEMU defconfigs to latest longterm kernel 5.4.88.

Please note that QEMU boards not based on 5.4.y were ignored:
- qemu_csky810_virt_defconfig
- qemu_csky807_virt_defconfig
- qemu_csky610_virt_defconfig
- qemu_csky860_virt_defconfig

Tests were carried out on all QEMU boards using Gitlab [1] (commit
message was slightly different, but the patch is identical)

Additional actions needed were:
- board/qemu/sh4-r2d: Remove one of the two kernel patches [2] provided

16430fd8c6 configs/qemu_arm_vexpress_tz_defconfig: build start-qemu.sh
When tags was added by commit 011206b2bf
to detect the qemu command line, the qemu_arm_vexpress_tz_defconfig
was ignored due to a build issue.

This build issue has been fixed by previous patches, so we can
enable the runtime testing by adding the tag in the readme.txt
and the post-image script in the defconfig.

Since Qemu from HOST_DIR is now executed directly from BINARIES_DIR,
we can remove all the string before "qemu-system-*".

3fc3289a3f board/qemu/post-image.sh: execute from BINARIES_DIR
Usually the qemu command line start directly with "qemu-system-<arch> ...".
But the command line for qemu_arm_vexpress_tz_defconfig start by doing
"cd output/images && ../host/bin/qemu-system-arm". This is necessary
since boot binaries, except BL1, are primarily loaded via semi-hosting
so all binaries has to reside in the same directory as QEMU is started
from [1].

To order to handle this case correctly, update the post-image.sh used
by all qemu defconfigs to execute qemu from BINARIES_DIR.

Since we have to change the current directory use a subshell to
restore the current directory after Qemu execution.

780af51d86 board/qemu/ppc-mpc8544ds: apply Debian patch fixing wrong mcpu
When building the linux kernel for PPC_85xx cpus with GCC 8, the build fail with:

  powerpc-e500v2-linux-gnuspe-gcc: error: unrecognized argument in option '-mcpu=powerpc'
  powerpc-e500v2-linux-gnuspe-gcc: note: valid arguments to '-mcpu=' are: 8540 8548 native

"GCC started treating "PowerPC" and "PowerPC SPE" as two different architectures and
that's the reason for the reduced -mcpu list." [1]

As suggested in the crosstool-ng issue [1], apply the Debian patch to avoid
-mcpu=powerpc or -mcpu=powerpc64.

5259a39c7a configs/qemu_mips64r6: fix Linux kernel build with gcc 10.x
From [1]

"GCC 10 (PR 91233) won't silently allow registers that are not architecturally
available to be present in the clobber list anymore, resulting in build failure
for mips*r6 targets in form of:
...
.../sysdep.h:146:2: error: the register ‘lo’ cannot be clobbered in ‘asm’ for the current target
  146 |  __asm__ volatile (	 \
      |  ^~~~~~~

This is because base R6 ISA doesn't define hi and lo registers w/o DSP extension.
This patch provides the alternative clobber list for r6 targets that won't include
those registers."

Since kernel 5.4 and mips support for generic vDSO [2], the kernel fails to build
for mips r6 cpus with gcc 10 for the same reason as glibc.

5cb0bae4bf board/qemu/aarch64-virt/linux.config: enable VIRTIO_FS driver
virtio-fs allow sharing a directory between the host and the guest.
It require virtiofsd daemon running before starting Qemu.

The wiki [1] recommand to enable the following kernel options:

      CONFIG_VIRTIO
      CONFIG_VIRTIO_FS
      CONFIG_DAX
      CONFIG_FS_DAX
      CONFIG_DAX_DRIVER
      CONFIG_ZONE_DEVICE

But virtio-fs works fine with only VIRTIO_FS.

Note: ZONE_DEVICE can only be enabled on aarch64 since kernel >= 5.7.
ARCH_ENABLE_MEMORY_HOTREMOVE support is missing for previous kernel [2].

This information is now incorrect since we are using host-qemu
package, currently at 4.2.0 version, to do a runtime test since
0c79350638.

For m68k-q800, we can use the upstream qemu since 4.2.0 release
[1].

So, remove this line from the readme.txt.

80a044703a configs/qemu: update defconfigs to Linux 5.4.35
Linux version are changed to the new LTS kernel 5.4.35 for all qemu
defconfigs, except for riscv and csky. Thoses defconfigs are left
unchanged because they require either a custom Linux repository
or a specific kernel header version causing some difficulties when
upgrading to 5.4.35.

Update the nios2-10m50 linux.fragment to update the .dtb build directory
due to a change in kernel 4.20 [1]:

    nios2: build .dtb files in dts directory

    Align nios2 with other architectures which build the dtb files in the
    same directory as the dts files. This is also in line with most other
    build targets which are located in the same directory as the source.
    This move will help enable the 'dtbs' target which builds all the dtbs
    regardless of kernel config.

    This transition could break some scripts if they expect dtb files in
    the old location.

For x86 and x86_64 kernel, add the CONFIG_PCI symbol due a change in kernel
5.0 [2]. The option was previously enabled by default (default y).

    PCI: consolidate PCI config entry in drivers/pci

    There is no good reason to duplicate the PCI menu in every architecture.
    Instead provide a selectable HAVE_PCI symbol that indicates availability
    of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the
    rest in drivers/pci.

Update the kernel of ppc-mac99 defconfig added in Buildroot 2019.08.

This version bump was tested on gitlab [4] using the newly introduced
boot-qemu-image.py script [5].

575493c186 board/qemu: add post-image script for gitlab qemu testing
This commit add a post-image script to be used by each qemu board
defconfig in order to generate start-qemu.sh in BINARIES_DIR. The
start-qemu.sh script can be used by Buildroot user to start Qemu
or by a gitlab CI.

To find the correct qemu command line, we use the second post script
argument which must contain "$(BR2_DEFCONFIG)"

    BR2_ROOTFS_POST_SCRIPT_ARGS="$(BR2_DEFCONFIG)"

The post-image script expect something like
"/path/to/qemu_aarch64_virt_defconfig" in BR2_DEFCONFIG.

Doing a basename allow to retrieve the name of the defconfig file that
should match on on the "tag" previously introduced in readme.txt files.

For running in the CI, as well as running from a remote machine (e.g. on
a remote build machine), it is better not to start in graphical mode,
but only with the serial line attached to the terminal. The post-build
script prepares two sets of arguments for each case, graphical or
serial, and stores them in the start-qemu.sh script, which then decodes
which to use, based on an argument on the command line (default is still
graphical)

sh4/sh4eb needs a special handling by adding "-serial stdio -display
none"; others only require "-nographics". Some qemu command lines
already contain "-serial stdio", but that does not play nicely with
"-nographics", we remove that when going serial-only (although this
might seem counter-intuitive).

Finally, we ensure the script uses our qemu-system (if it was built).

011206b2bf board/qemu: add defconfig file name as tag after the qemu command line
This commit add the name of the Qemu defconfig file after each
qemu command line in order to retrieve it easily.

Since a readme.txt can be shared between several Qemu defconfig, we
need at least one qemu command line in readme.txt for each defconfig.

For now, ignore the qemu_arm_vexpress_tz_defconfig since it fail to build
due to python script issue [1]. Anyway the arm vexpress boot is tested
with qemu_arm_vexpress_defconfig.

278f908d55 configs/qemu{x86, x86_64}: add a serial console
The current Buildroot defconfigs for qemu_x86 and qemu_x86_64
instantiate a console on tty1, which appears on QEMU's
graphical window. Add a console on the serial port (ttyS0) to
be used later for gitlab testing.

This change is need since the script used for gitlab testing
needs to use a serial output with pexpect.

This change is similar to the one made for raspberrypi [1] to
handle HDMI and serial console:

This requires three changes:
 1. have two 'console=' entries in the kernel command line: tty1,
    then ttyS0;
 2. change BR2_TARGET_GENERIC_GETTY_PORT to "console", so it starts
    a getty on the last console= passed to the kernel, ttyS0;
 3. add a new getty on tty1 to the generated inittab.

Step 2 is actually obtained by removing BR2_TARGET_GENERIC_GETTY_PORT
entirely from the defconfigs, since "console" is the default value.

Step 3 requires a post-build script since the Buildroot makefiles can
configure only one console.

Note: instead of simply adding a new getty on ttyS0 (which would
work) this patch actually changes BR2_TARGET_GENERIC_GETTY_PORT to
instantiate a console on UART, then adds back tty1 via
post-build.sh. This is done only to avoid the "GENERIC_SERIAL" comment
where we instantiate a console on QEMU graphical window, then
instantiate a really-serial console on another line.

The result is these two inittab lines:

  console::respawn:/sbin/getty -L  console 0 vt100 # GENERIC_SERIAL
  tty1::respawn:/sbin/getty -L  tty1 0 vt100 # QEMU graphical window

a0971ec7ec configs/qemu_arm_vexpress_tz: Armv7-A emulation with TrustZone services
This change introduces a Qemu board for an Armv7-A target executing
with OP-TEE secure world services. The target Linux based normal world
embeds the standard minimal filesystem with OP-TEE non-secure components
embedded files from OP-TEE test, examples and benchmark packages.

qemu_arm_vexpress_tz_defconfig differs from qemu_arm_vexpress_defconfig.
Supporting both secure and non-secure worlds on the Arm target mandates
a secure world, here OP-TEE OS, and a bootloader to boot both worlds,
here TF-A (boot/arm-trusted-firmware). Here non-secure Linux kernel is
booted through U-boot

  TF-A bootloader (BL1/BL2) => OP-TEE (BL32) => U-boot (BL33).
  | Executes as secure         | Secure         | Execs as Non-secure
  | Loads BL32/BL33 in RAM     | Jumps to BL33  | Always booted after
  | Jumps to BL32 once done    | as Non-secure  | secure world inits

Vexpress and vexpress-tz defconfigs also differs in that Qemu emulates
a Cortex-A9 in the former and a Cortex-A15 in the later. Cortex-A15
is the Armv7-A CPU used in upstream TF-A and OP-TEE OS packages hence
selected here.

Defconfig adds a fragment to the Linux kernel native configuration to
enable OP-TEE driver support.

Defconfig adds a fragment to the U-Boot native configuration set boot
command, enable semihosting and remove U-Boot persistent environment
storage support.

The defconfig also enables build of the Qemu emulator in case the
system installed Qemu does not yet support CPU TrustZone secure state.

626c9705d2 board/qemu: ensure root is available before mounting it
On my machine, it happens once in a while that the virtualised machine
boots too fast for the rootfs to be available at the time the kernel
tries to mount it.

For example, board/qemu/arm-vexpress/readme.txt suggested changing
"-smp 1" up to "-smp 4". But doing so here causes a kernel panic:

    VFS: Cannot open root device "mmcblk0" or unknown-block(0,0): error -6
    Please append a correct "root=" boot option; here are the available partitions:
    1f00          131072 mtdblock0
     (driver?)
    1f01           32768 mtdblock1
     (driver?)
    Kernel panic - not syncing: VFS: Unable to mount root fs on
    unknown-block(0,0)

So, add the oh-so-useful 'rootwait' option to all kernel command lines
for qemu defconfigs.

This reverts commit 18e8cf159177100e69d528293f8cf6875c0b1bca (kernel)

The last Qemu kernel update [1] introduced a regresion in sh4 SCIF
serial device. Some keyboard presses are very slow to be taken into
account, perhaps not even taken into account at all. This would
explain why our test infrastructure doesn’t manage to login as root
[2][3][4].

git bisect reported a kernel patch from 4.11, increasing RX FIFO
trigger defaults value for sh-sci (H)SCIF. The kernel patch itself
looks good but the Qemu emulation is not ready to handle this new
setting.

>From Qemu (2.12.0): target/sh4/README.sh4
"Configuration of the second serial port (SCIF) is supported. FIFO
handling infrastructure has been started but is not completed yet."

We can't use the first serial port (ttySC0) because it's the second
SH UART that's emulated by Qemu.

In order to be able to test sh4 architecture with newer kernel,
revert to the old behaviour.

(1) - Probably an endian issue with 8139 emulation/driver
(2) - There's a network interface, but enabling it in qemu fails
(3) - Kernel patch required, switched to devicetree usage

5c5f1b0743 configs/qemu_x86_defconfig: remove kernel options that need openssl
Wireless support ends up enabling CONFIG_SYSTEM_TRUSTED_KEYRING, which
requires openssl to be available on the host, so disable wireless
support, which isn't needed in Qemu.
