qi-refactor-for-multi-cpu-add-s3c6410-base.patch

This patch makes qi source structure cpu-centric, and allows multiple CPUs
to be handled with the board definitions inside the CPU dirs.

You have to make a particular CPU version of Qi now, which you can do by
a shell command like this:

make clean ; make CPU=s3c2442 && make CPU=s3c6410

which gets you

$ ls -l image/
total 744

The 6410 support in there is enough to send a character "U" on the 6410 SMDK

Because the product naming is not defined, currently the device targeted for 6410
is called "TLA01"
