7Currently the support for these CPUs is pretty minimal, but enough to
8get things going.  (much like the support for the Galileo Eval Board)

10There is a framework in place to enable the L2 cache, and to program
11the BATs.  Currently, there are still problems with the code which
12sets up the L2 cache, so it's not enabled. (IMHO, it shouldn't be
13anyway).  Additionally, there is support for enabling the MMU, which
14we also don't do.  The BATs are programmed just for the benefit of
15jumping into Linux in a sane configuration.
16
17Most of the code was based on other cpus supported by U-Boot.

19If you find any errors in the CPU setup code, please send us a note.
