| This file contains status information for the port of U-Boot to the | |
| Motorola mpc74xx series of CPUs. | |

| 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. | |
| Thanks, | |
