- * The aim of this code is to bring the machine from power-on to the point
- * where we can jump to the the main coreboot entry point hardwaremain()
- * which is written in C.
- *
- * At power-on, we have no RAM, a memory-mapped I/O space, and we are executing
- * out of ROM, generally at 0xfff00100.
- *
- * Before we jump to harwaremain() we want to do the following:
- *
- * - enable L1 I/D caches, otherwise performance will be slow
- * - set up DBATs for the following regions:
- * - RAM (generally 0x00000000 -> 0x7fffffff)
- * - ROM (CONFIG_ROMBASE -> CONFIG_ROMBASE + CONFIG_ROM_SIZE)
- * - I/O (generally 0xfc000000 -> 0xfdffffff)
- * - the main purpose for setting up the DBATs is so the I/O region
- * can be marked cache inhibited/write through
- * - set up IBATs for RAM and ROM
- *

- * - I/O (generally 0xfc000000 -> 0xfdffffff)
