85 | * Flash Memory Layout | |
86 | * | |
87 | * 2 MB Flash Bank 0 runs in 8-bit mode. In Flash Bank 0, the 32 kB | |
88 | * sector SA3 is obscured by the 32 kB serial/TOD access space, and | |
89 | * the 64 kB sectors SA19-SA26 are obscured by the 512 kB PLCC | |
90 | * containing the fixed boot ROM. (If the 512 kB PLCC is | |
91 | * deconfigured by jumper, this window to Flash Bank 0 becomes | |
92 | * visible, but it still contains the fixed boot code and should be | |
93 | * considered read-only). Flash Bank 0 sectors SA0 (16 kB), SA1 (8 | |
94 | * kB), and SA2 (8 kB) are currently unused. | |
95 | * | |
96 | * 2 MB Flash Bank 1 runs in 16-bit mode. Flash Bank 1 is fully | |
97 | * usable, but it's a 16-bit wide device on a 64-bit bus. Therefore | |
98 | * 16-bit words only exist at addresses that are multiples of 8. All | |
99 | * PROM data and control addresses must be multiplied by 8. | |
