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 as corenet deivces use PBI-RCW based intialization. So, for corenet deives, SPL bootloader use values provided at compilation time. These values can be defined in board specific config file.
