Currently the support for these CPUs is pretty minimal, but enough to
|
||
|
|
get things going. (much like the support for the Galileo Eval Board)
|
||
|
|
|
||
|
|
There is a framework in place to enable the L2 cache, and to program
|
||
|
|
the BATs. Currently, there are still problems with the code which
|
||
|
|
sets up the L2 cache, so it's not enabled. (IMHO, it shouldn't be
|
||
|
|
anyway). Additionally, there is support for enabling the MMU, which
|
||
|
|
we also don't do. The BATs are programmed just for the benefit of
|
||
|
|
jumping into Linux in a sane configuration.
|
||
|
|
|
||
|
|
Most of the code was based on other cpus supported by U-Boot.
|
||
|
|
|
||
|
|
If you find any errors in the CPU setup code, please send us a note.
