I am trying to set up a NAND_SPL bootloader for a different PowerPC processor.
Good. Additional board/cpu support for this new U-Boot NAND booting feature is very welcome. :-)
I want to store the environment variables in the NAND Flash at a location above the boot loader, so that I can reprogram the bootloader without overwriting the variables when I copy the u-boot-nand.bin image into the NAND flash.
Understood. Just a side note: You could use a command that runs "saveenv" upon updating the U-Boot image. This way you won't loose the environment.
However in the changes made on Sept 12, the include/environment.h file was modified to define ENV_IS_EMBEDDED whenever CONFIG_NAND_U_BOOT is defined.
Is there any reason that this configuration setting cannot be moved into the board specific include file instead ?
Not really. We can move this define into some board specific place. We should use the define "CFG_ENV_IS_EMBEDDED" in the board config file though and not the define "ENV_IS_EMBEDDED".
Best regards, Stefan
