RE: [Ltib] new LTIB platform diffs for submission

[Kevin Wells]

Hi Stuart,

This issue showed up with the 2.6.26 kernel release (maybe .27).
The machine specific headers were moved to 
./arch/arm/mach-<platform>/include/mach
and they way the link to the ./include/asm-<arch>/arch/ was generated was
changed (or just removed).

I see revision 1.6 of the kernel-common.tmpl had a workaround for this issue, 
but
the latest version (1.8) seems to have regressed back to the pre-workaround
./include/asm-<arch>/arch/mach-<board> method.

I think all platforms that use a kernel revision of .26 or later and have the
[*] Include kernel headers options enabled (or have a package that includes it)
will have this same issue.

I looked at this a while back and did have a temporary fix for this issue, but
it required another var in the platform specific main.lkc file and a small 
change
in the kernel common template. Basically, if the var didn't exist, the link
in ./include was used to copy those files. If the var did exist, the var was
used as the mach-<board> name to find the include path. This solution wasn't too
elegant as it would require post 2.6.26 platform submitters to add the variable
to their main.lkc file.

I'm still not sure how to approach this issue. An equivalent direct link in the
kernel include tree doesn't seem to be there anymore so parsing the kernel
version may not be enough without the mach name also. If anyone has an ideas on
how to tackle this, I'll take a shot at it.

Here is a link to the previous thread:

thanks,
kevin
