Stefan,
Can't you just remove this config.mk file completely? CONFIG_SYS_TEXT_BASE can be moved to the config header instead. What else is this file needed for?
Could you please explain which config header you are referring to here? Do you mean include/configs/spear..... ?
Yes.
For SPEAr310 and SPEAr320, config.mk is needed to make image (by specifying FLASH=PNOR during compile time) that can access CFI compliant PNOR flash.
In the example above (spear300), only CONFIG_SYS_TEXT_BASE is left in config.mk. This can be moved to the config header (include/configs/spear-xxx- h).
You should be able to move the other remaining options (PNOR...) to boards.cfg. Or is this not possible?
It is possible and it adds to the clarity, thanks for this nice suggestion. I'll remove all the config.mk files from the board/spear/spearxx/ directories and add targets in boards.cfg for making u-boot build with environment variables placed in PNOR flash.
Best Regards Amit Virdi
