According to common eMMC partition table for Android boot (see PARTS_DEFAULT definition in include/configs/dra7xx_evm.h), "bootloader" partition (where u-boot.img is stored) starts at 256 KiB. Which is equal to 512 sectors (as 1 MMC sector size is 512 bytes).
This patch fixes CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR constant so that it points to correct address of "bootloader" partition and SPL is able to read, parse and run u-boot.img correctly.
This change was originally done as part of patch [1] in omapzoom u-boot. Without this patch, SPL fails to parse U-Boot header with next error:
mkimage signature not found - ih_magic = 4814325aWhile at it, also fix U-Boot partition size, which is 384 KiB (as stated in include/configs/dra7xx_evm.h).

Good catch. But please keep the value in hex for consistency, thanks!
