17c516d67a configs/qemu_aarch64_sbsa_defconfig: use ARM cortex a57
Cortex-a53 is not a vaild CPU supported by the SBSA reference machine
[0], so qemu fails to boot in our current defconfig:

  qemu-system-aarch64: sbsa-ref: CPU type other than the built-in cortex-a57 not supported

Use ARM cortex-a57 which is the CPU that SBSA was meant to emulate [1]

A following patch will switch to the kernel 5.15 for all qemu

The BLK_DEV_IDE_PMAC driver has been removed from the kernel, so use the
libata replacement PATA_MACIO. This requires enabling ATA and BLK_DEV_SD
for the disk to show up, and changing the command line to use /dev/sda.

YENTA depends on PCCARD, so enable it.

b36c4e594c configs: remove qemu_csky defconfigs
We are going to remove the gcc fork for csky since it doesn't build
with the latest compilers (gcc 8, 10, 11 tested) [1].

Removing theses defconfigs and the csky gcc fork has become unavoidable
since the Buildroot Docker image used by the gitlab CI will switch soon
to Debian bullseye soon [2].

The cksy gcc fork based on gcc 6 has not been updated since it has been
added to Buildroot [3]. Since then, csky has been added to binutils and
gcc but using the latest upstream version (binutils 2.37 and gcc 11) is
not yet possible due to build issue with glibc 2.34 [4].

Moreover, qemu_csky defconfigs was to be used with the csky qemu fork
(based on Qemu 3.x) added by commit [5] and removed by commit [6].
Since then it's not possible to do a runtime test with theses
defconfigs.

Theses defconfigs can be added back later if the csky toolchain support
is fixed and csky supported by upstream Qemu.

3efb5e31fc board, boot, package: remove usage of startup.nsh in EFI partition
The startup.nsh file is useless to boot EFI payloads. We just need to
follow the naming detection specified in the UEFI spec.
The EFI payload need to be placed in the boot/efi folder in the EFI partition
and follow the architecture naming as described below:
32bit : bootia32.efi
x64 : bootx64.efi
aarch32 : bootarm.efi
aarch64 : bootaa64.efi

This naming is already right in the packages involved (systemd, grub2,
gummiboot), therefore we just need to drop the generation of the
startup.nsh file.

The usage of the startup.nsh in genimage is also dropped to avoid errors in
the image generation.

The issue was initially reported to gcc [1] where it was analized.
As suggested, change the struct mdesc_elem * accesses from the end
of mdesc to those from the beginning of the data array.

Update the prototype of node_block(), name_block() and data_block()
since the code really seems to want to do is to compute the address
somewhere into the chunk pointed to by hp.

a8466cc5ac configs/qemu_aarch64_sbsa_defconfig: new config for QEMU sbsa-ref
This introduces a configuration for the SBSA reference machine under
QEMU that is intended for developing and testing firmware. It consists
of ATF that load EDK2 as BL33 which in turn will load GRUB2.

Included with the board files is a minimal kernel configuration, almost
identical to that of board/qemu/aarch64-virt/linux.config. The main
difference is the addition of ACPI which is preferred over DTB for
booting an UEFI system.

15d3a7226d configs/qemu_arm_vexpress_tz: bump versions and update
- Bump TF-A to version 2.4.
- Bump u-boot to version 2021.01.
- Bump kernel to version 5.11.3.

We switch TF-A to a single FIP image. Thanks to this, TF-A does not need to
use semihosting to load the various BL* anymore (but U-Boot still does).
Update the readme.txt accordingly.

We switch to a u-boot image for the ramdisk. This removes the need to
update the fdt chosen node manually in the bootcmd.

While at it, we drop the generation of the kernel dtb, which we do not use.
In this config, we are indeed using the dtb generated on-the-fly by qemu
and amended by TF-A.

When tags was added by commit 011206b2bf
to detect the qemu command line, the qemu_arm_vexpress_tz_defconfig

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.

5259a39c7a configs/qemu_mips64r6: fix Linux kernel build with gcc 10.x

"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

      |  ^~~~~~~

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].

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

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.

 fix U-Boot version to 2019.01, download tarball of TF-A instead of git]

6e359e26e3 configs/csky_gx6605s: bump kernel to 5.0 and use buildroot toolchain
The most important change is to use the toolchain compiled by
buildroot itself. We also bump kernel to 5.0 with kernel.org.

Gx6605s' PHYS_OFFSET if 0x10000000 and we make qemu and gx6605s the
same to ease maintaince. This PHYS_OFFSET is also OK for 610 qemu.

In this patch we add gx6605s.dts in board/csky, because linux-5.0
doesn't contain gx6605s.dts in its tree.
