This is linux support for exynos. You have to modify files in this
directory to add support for I-pipe.

I quote the guide "To start porting the I-pipe patch to a new board,
look in these directories to see where the hardware timer and its
interrupt are handled (usually arch/arm/mach-X/time.c) and where
cascaded interrupt, if any, are decoded (usually arch/arm/mach-X/irq.c).
In the rest of this document we will call these files time.c and irq.c,
even though they may have another name for your board. "

The omap support is modified to support the I-pipe. You can look at how
it is done and imitate for exynos. To find the files modified by the
I-pipe kernel, you can:
- run lsdiff on the I-pipe patch
- grep CONFIG_IPIPE in the I-pipe patched kernel
