(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. + +Thanks, +Josh |
