Priyanka Jain - Oct. 31, 2013, 9:45 a.m.
Existing eSDHC SPL framework assumes booting from sd-image
with boot_format header which contains final u-boot Image
offset and size. No such header is present in case of
corenet devices like T1040.

So, for corenet deives, SPL bootloader use values provided
at compilation time. These values can be defined in board
specific config file.
