Hello,
I'm not sure if this is the proper way to submit a patch - please feel
free to let me know what needs to be changed, if anything.
Thanks,
Daniel Schuler
===================
The current SBC-2410A board from Embest ships with 2MiB of NOR FLASH,
for which CONFIG_AMD_LV160 has been defined in include/configs/sbc2410x.h
Also, CONFIG_ENV_ADDR has been made more generic by making it depend on
CONFIG_ENV_SIZE, so that only the latter needs to be changed to modify
the size of the environment.
In board/sbc2410x/flash.c, the appropriate #elif and case statements have
been added to support this chip.
