>Applied this patch on mainline branch, I see warning.  It seems like CONFIG_PHYS_64BIT is not taking effect, the sizeof phys_addr_t is 4 bytes instead of 8 byte.

Due to removal of CONFIG_PHYS_64BIT in dra7xx_evm.h, phys_addr_t set to 4, and due to SDRAM init would have failed and u-boot prompt did not appear.

I have defined CONFIG_PHYS_64BIT in dra7xx_evm.h, I did not see any warning and I could see u-boot prompt, worked fine.
