[U-Boot] [PATCH 1/1] Changes for single binary image for u-boot for NAND/OneNAND flash.

[Pillai, Manikandan]

Hi,

Single binary image - The type of flash is not selected during compile time. The
U-boot scans the flash available(as of now whether it is NAND or OneNAND) and
starts using the first flash detected as the ENV storge. To select this option,
I added a #define CONFIG_ENV_IS_RUNTIME_SEL(env storage selection during runtime).



Regards
Mani
