19575e9e9e board/raspberrypi: add Raspberry Pi Zero 2 W
The Raspberry-Pi Zero 2 W is an affordable single board computer. It is
a more powerful drop-in replacement for the Raspberry Pi Zero W.

The board incorporates an Raspberry-Pi RP3A0 system-in-package (SiP) with
a Broadcom BCM2710A1 and 512MB LPDDR2 SDRAM. The CPU is a quad-core 1Ghz
64-bit Arm Cortex-A53. As for other Raspberry-Pis it also provides
2.4GHz 802.11 b/g/n Wifi, Bluetooth 4.2 and BLE.

The BCM2710 cpu is similar to the Raspberry-Pi 3, it uses the same
kernel configuration as the Raspberry-Pi 2 and 3.

689b9ac439 package/rpi-firmware: rework boot/config file handling
Try to be less smart (focused on the one target/one use-case),
instead reduce the rpi-firmware package to a selectable list
of (verbatim) installed firmware files.

- change rpi-firmware config handling from rpi-variant/rpi-flavour
  choices to bootcode.bin, pi-default/-extended/-cut-down and
  pi4-/default/-extended/-cut-down selection

- add BR2_PACKAGE_RPI_FIRMWARE_CONFIG_FILE option to select installable
  config.txt file

- remove config.txt modify code/handling from raspberry post-image.sh
  script

- add different customized config.txt files to the raspberry board
  section

- change dtoverlay krnbt from 'dtoverlay=miniuart-bt,krnbt=on' to extra line
  with explanation comment

- change raspberry defconfigs to select appropiate rpi-firmware
  and config.txt files

- change genimage-raspberrypi4.cfg/genimage-raspberrypi4-64.cfg to
  use start4.elf and fixup4.dat

- update board/raspberrypi/readme.txt (add optional files fixup4.dat,
  start4.elf and zImage)

With this changes a better support for custom use-cases should
be possible, specially multi-target SD cards as suggested by
Stefan Agner ([1]).

5352a77102 board/raspberrypi: use kernel Bluetooth mode
The default setting with miniuart-bt requires hciattach which is a
deprecated utility in BlueZ.  Setting the krnbt parameter switches to
the modern method of using serdev in the kernel removing the need for
any userspace configuration to enable the Bluetooth controller.

This is documented as applying to all Raspberry Pi variants so just
enable it globally.

51d6d6c580 Fix rasberry Pi 64bit firmware overlay inclusion
This patch enables the inclusion of the Pi's overlays. Previously
the overlays were not included in the genimage configuration.
This patch ensures overlays are included in the sdcard (when
enabled) by defaulting to the inclusion of an empty
output/images/rpi-firmware/overlays directory in genimage cfg.

The Pi's overlays are built with the following config
variables:
BR2_PACKAGE_RPI_FIRMWARE=y
BR2_PACKAGE_RPI_FIRMWARE_INSTALL_DTBS=y
BR2_PACKAGE_RPI_FIRMWARE_INSTALL_DTB_OVERLAYS=y
BR2_LINUX_KERNEL_IMAGE_TARGET_CUSTOM=y
BR2_LINUX_KERNEL_IMAGE_NAME="Image"
BR2_LINUX_KERNEL_IMAGE_TARGET_NAME="Image modules dtbs"

After building, the dtbo files are present in the
output/images/rpi-firmware/overlays directory but not added
to the sdcard because they are missing from the genimage cfg
file.

650818fb3a configs/raspberrypi0w_defconfig: new defconfig for Raspberry Pi Zero W
Up to now, Raspberry Pi Zero W (rpi0w) could be built with the normal
raspberrypi0_defconfig. However, then you don't have support for the
Bluetooth out-of-the-box, which makes using a W a bit pointless.

Therefore, create a separate defconfig for the W. It is a copy of
raspberrypi0_defconfig with the following changes:
 - Add DT overlays (from rpi-firmware) to support Bluetooth.
 - Pass --add-pi3-miniuart-bt-overlay to post-image.sh.

Since there is now a separate raspberrypi0w_defconfig, the W support
can be removed from raspberrypi0_defconfig.

	sed: -e expression #1, char 8: extra characters after command

The issue comes from the use of $1 instead of $arg to extract the gpu_mem
value. $1 is the $(BINARIES_DIR) which leads to a sed expression error.

Also, it adds the error flag to the shell script to prevent from such situation
and terminate the build in error.

b159b15d07 configs: add Raspberry Pi 3 defconfig
So far identical to the rpi2 one except for the dts file as the SW runs in
32bit mode.

babf1190b3 raspberrypi, raspberrypi2: document the two consoles (UART+HDMI)
The defconfigs for the Raspberry Pi boards start a console on HDMI in
addition to the classic one on UART. Document this feature in the
readme.

20878a1017 raspberrypi, raspberrypi2: add a serial console
The current Buildroot defconfigs for Raspberry Pi and Raspberry Pi 2
instantiate a console on tty1, which appears on HDMI. Add a console on
the serial port (ttyAMA0) to be more consistent with other defconfigs
and provide a better out-of-the-box experience to users used to have a
serial console from Buildroot defconfigs.

This requires three changes:
 1. have two 'console=' entries in the kernel command line: tty1,
    then ttyAMA0;
 2. change BR2_TARGET_GENERIC_GETTY_PORT to "console", so it starts
    a getty on the last console= passed to the kernel, ttyAMA0;
 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 ttyAMA0 (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 an HDMI console, 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 # HDMI console

8dd797a054 configs/raspberrypi*: update them to use genimage
Update the raspberrypi and raspberrypi2 configs to use genimage directly
to build the image.
Update the documentation to reflect this, and drop the volatile rootfs
option since it doesn't make much sense and it's not easily integrated
with the genimage configurations.

6f999784b8 boards/raspberrypi: update instructions
Now that we have a sanitised set of defconfig files, and we no longer
support non-DT setups, update and simplify the board readme file.

d8649ca874 configs/raspberrypi: update the DT-enabled config
Update to the latest stable kernel version; build an in-tree DTB; use
a in-tree defconfig; enable C++ (to match what we have in the non-DT
variant); do not install DTB overlays (this minimalist config does not
make use of them).

Generate the DTBs for both the "original" variant (A and B) and the
"Plus" variant (A+ and B+).

Drop our custom linux defconfig file now we use an in-tree one.
