[Buildroot] PowerPC kernel headers

[Buildroot] PowerPC kernel headers

[Fredrik Roubert]

Hi!

Recently the possibility to use the Linux 2.6.18 kernel headers has been
added to buildroot. However, the correct asm directory for PowerPC has
changed from "ppc" to "powerpc", as part of the move to a unified kernel
architecture for 32 and 64 bit PowerPC system.

The attached patch updates kernel-headers.mk to use asm-powerpc when
building with the 2.6.18 kernel headers.

Cheers // Fredrik Roubert

I just checked in r16345 that uses headers_install for the full kernel.
This should make your patch unnecessary, i'd say. Please confirm.

Good. Thanks for checking and kind regards,

That's correct. With patch r16345 my patch to kernel-headers.mk is not
needed anymore. (There is however a bug in r16345 that must be fixed
first, see separate post.)
