[Buildroot] [PATCH v2 00/15] Add support for STM32F469-DISCO & STM32F469-DISCO boards

[Lee Jones]

After this set is applied and you have the correct toolchain installed it
should be trivial to configure, build and flash the; bootloader, DTB and
kernel (with CPIO rootfs attached) to the board(s).

[Buildroot] [PATCH v2 09/15] boards: stm32f469-disco: Add OpenOCD patch to support on-board flash chip

[Lee Jones]

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.

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.

You'll notice, in contrast to the STM32F469, there aren't any patch
directories required for this board.  That's because it is well
supported in each of the upstream repos, and has been for some time.

In the previous review, forgot to mention that you should add a:

	depends on BR2_arm

here.

Other than that:

There are waaaaaaaay too many patches here.

There should be only three patches:

 1/ One adding afboot-stm32
 2/ One adding the stm32f429 defconfig
 3/ One adding the stm32f469 defconfig

Splitting further than that is really unnecessary. You are even adding a
file in PATCH 2, to simply move it in PATCH 3. Ditto with PATCH 4/5 and
6/7!

Could you rework the patch series to merge things a bit?

Thanks!

I've applied to next, after doing the following changes:

 - Changed the commit title to "afboot-stm32: new package", which is
   our standard for package additions.

 - Added the "depends on BR2_arm" dependency.

Thanks!
