[HELP] ARM Cross Compilation Toolchain

[E3V3A]

you can download original kernel sources and make a diff....but more recent kernel is not really useful as long samsung not release the driver sources...

So good news, it is now partially working! I'll throw all my work on the wiki!

I say "partially", because a few pieces doesn't compile due to (a) GCC4.7 throws errors for "inlining" (see above) where GCC <= 4.6 just ignored them. (b) The CodeSourcery GLIBC libraries are not really for our processor arch, so we got screwed there by Mentor Graphics Lite edition! This means that there are two files that trows ARM processor errors, when compiling for kernel image only. So given this horrible experience trying to get Code Sourcery shit working, I'm gonna personally slap the next person who asks for or attempts to compile kernels using their tools!

1. So about diffing. The kernel is "sold" as 2.6.35.11, but the sources are dumping out 2.6.35.13... However, I cannot find any sources higher than 2.6.35.9...
This is the extra versions. Do they matter much? Not sure what to do here.

2. What driver sources are you talking about, specifically?

Thanks, I missed that one...

1. What does that driver do?
2. Is there any particular reason why Smasung keep working on the 2.6.35 kernel, when there's already 2.6.39?

According to README doc's the 2.6.xx should only contain bugfixes, so I would imagine that we'd have a more stable, compact and efficient kernel if we were using a later version? But what do I know...

Is possible to use it also for f series?
