This is a _very_ small bootloader for STM32 platforms.
At submission afboot-stm32 supports the following boards:
stm32429i-eval
stm32746g-eval
stm32f429i-disco
stm32f469i-disco

There's no real reason to select host-openocd here. It's not needed to
build/use the bootloader. One could use a different flashing program.

Since you're sourcing from Github, please add a .hash file for this new
package.

Get rid of the -D option here.
Other than those minor nits, it looks good.

Unfortunately, the toolchain built with Buildroot does not currently
support this platform. Thus, the tested-working one is being referenced
instead. Once the Buildroot toolchain works, this will be swapped out.

I think this line is useless, since it will be the only option anyway
for Cortex-M, so it should already be the default. It isn't the case?

This means the defconfig will not build without first installing this
toolchain in this specific location. This isn't acceptable as it breaks
the point of defconfigs, and will break our Travis-CI testing of
defconfigs.
We need to either make the internal toolchain work with Cortex-M3, or
alternatively, make the external toolchain logic support the OSELAS
toolchain. I *think* I tried the latter option, but ran into troubles,
but I can't remember which ones.

Not needed since you have BR2_GLOBAL_PATCH_DIR. Just put the kernel
patches in board/stmicroelectronics/stm32/stm32f469-disco/patches/linux.

Once each of the; bootloader, kernel, host utilities and rootfs have
been successfully built and packaged, this post-image script will
endeavour to flash the relevant images onto the board.

At the time of submission, the Mainline kernel does not currently
support the STM32f469. This patch adds a new DTS file which
contains some critical information to ensure a clean, visible boot.

At the time of submission, the Mainline kernel does not currently
support the STM32f469. This patch adds a new config fragment which
we can use to adjust the start of RAM address to 0.

At the time of submission, the Mainline kernel does not currently
support the STM32f469. This patch makes changes to the defconfig
to enable booting with the CPIO which Buildroot puts together.

This is not needed. Buildroot already sets those options when building
a kernel with BR2_TARGET_ROOTFS_INITRAMFS=y in the Buildroot
configuration. See linux/linux.mk, and search for
BR2_TARGET_ROOTFS_INITRAMFS.

At the time of submission, OpenOCD does not support the STM32f469.
This patch adds a new configuration file which provides some board
specifics required to correctly handle the stm32f469-disco dev
board.

At the time of submission, OpenOCD does not support the STM32f469.
This patch adds support for the STM32F469-DISCO's on-board flash
chip. Without this patch there is no way to flash the board.

Patches 2 to 9 should be squashed together. Indeed, PATCH 2 relies on
having all other patches applied, otherwise it won't work. For example
PATCH 2 references the post-image script, but it is introduced only in
PATCH 3.

Thomas
