[Buildroot] kernel header patches

[Buildroot] kernel header patches

[Patrick Ziegler]

Hi,

I'm working on different boards support to match our requirements.
Therefore I need to apply some patches to the kernel headers as well as
the kernel sources itself. Especially for header patches related to a
specific device I'm not sure how to enable them in the configuration.

In the Atmel device directory the variable KERNEL_HEADERS_PATCH_DIR will
be used to define a directory including some patches. But the 'ifeq'
check fails in 'kernel-headers-new.makefile'. In the previous version
(2010.05) it was possible to replace this check by a check on the shell.
But this will also fail with the new version (2010.08-rc1).

Is there an official way to apply patches to the kernel headers and
kernel sources depending on the board ?

Best regards

Patrick

For my Board I need to apply some minor patches to the kernel. My 
configuration looks like this:

Location of patches in project tree:
target/device/sheevaplug/SeagateDockStar/kernel-patches/
-> linux-2.6.34-0001-ABC.patch
-> linux-2.6.34-0002-XYZ.patch
-> DONOTUSENOW-linux-2.6.34-0002-XYZTesting.patch

.config includes:
BR2_LINUX_KERNEL_USE_CUSTOM_CONFIG=y
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE="target/device/sheevaplug/SeagateDockStar/SeagateDockStar-linux-2.6.34.1.config"
BR2_LINUX_KERNEL_PATCH="target/device/sheevaplug/SeagateDockStar/kernel-patches/"

The patches were correctly applied during kernel compilation via buildroot.

Regards,
Marcus

Thanks, but unfortunately this works only for the kernel compilation not
for the kernel headers.
