Hello u-boot users,
in the README-file you can read this:
- FLASH_BASE0_PRELIM, FLASH_BASE1_PRELIM, CFG_REMAP_OR_AM, CFG_PRELIM_OR_AM, CFG_OR_TIMING_FLASH, CFG_OR0_REMAP, CFG_OR0_PRELIM, CFG_BR0_PRELIM, CFG_OR1_REMAP, CFG_OR1_PRELIM, CFG_BR1_PRELIM: Memory Controller Definitions: BR0/1 and OR0/1 (FLASH)
So memory bank 1 shouldn't get used for SDRAM, but bank 2 and 3 ? *_PRELIM is the address before u-boot relocation to RAM, isn't it ? But *_REMAP after that ?
Whats CFG_FLASH_BASE good for, if i have to configure the memory bank base register value of my MPC875-board anyway with CFG_BR0_* ?
Further, i am now facing the problem, that my BR1 SDRAM-memory bank gets changed correctly at u-boot runtime, but the BR0-flash-memory-bank keeps its PRELIM-value when reaching the command shell.
I now wonder, if i misconfigured my board header file, or if not, where i shall add the new memory bank reprogramming code for flash space - in drivers/cfi_flash.c:flash_init() ?
One last question: I am porting u-boot to a not yet very popular developer board with a MPC875. Shall i add my changes although to your CVS repository ?
Thanks in advance
Josef
