[Buildroot] [PATCH] Add Armadeus systems APF9328 support.

[julien.boibessot at free.fr]

From: Julien Boibessot <julien.boibessot@armadeus.com>

The APF9328 is an i.MXL+FPGA based SOM (System On Module). Here only minimal support is added: booting Linux kernel (UART, Ethernet and NOR), Buildroot toolchain and JFFS2 rootfs.

[Buildroot] [PATCH] Add Armadeus systems APF9328 support.

[Thomas Petazzoni]

Hello,

Good to see Armadeus stuff coming into mainline Buildroot!

This should be wrapped at ~80 chars.

Those four options (or at least the first three) are very
user-specific. I don't think they should be part of a default board
configuration file.

Since two kernel patches are needed, you should have a defconfig that
explicitly tells which kernel version it wants:

BR2_LINUX_KERNEL_CUSTOM_VERSION=y
BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="3.1"

see configs/qemu_* for examples.

Thanks for the review.
More will come as soon as BR can handle Linux patches tarball
downloading ;-)

ok but if I set BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="3.1.1", it is not
saved by "make savedefconfig". Seems like there is a "bug" in BR when
custom kernel version == default one

Julien

Well, it's how savedefconfig behaves in the kernel. Just edit the file
manually afterwards - That way it will still work when we change the
default kernel version to be 3.2.

 In fact, that default for the custom kernel version is redundant.  We
already have a default kernel version, there's no point in having it twice.

 Patch follows.

 Arnout

[Buildroot] [PATCH] linux: remove default for custom kernel version

[Arnout Vandecappelle]

From: "Arnout Vandecappelle (Essensium/Mind)" <arnout@mind.be>

There already is a default kernel version, so it makes little sense to have
a default custom kernel version as well.  This default breaks the 'make
savedefconfig' if we want to force a specific version.
