[U-Boot] [PATCH v5 0/3] spl: Add support to load FIT from Filesystem

[Lokesh Vutla]

Some devices like MMC, USB can be formatted to a FS and can act as a boot media.
Given that FIT image load support in SPL support only raw devices, SPL should
also be able to support loading FIT image from a File system.
This series add support to load FIT image from a filesystem and also adding
hooks to FAT FS.

Testing:
DRA74-evm:
MMC Boot: http://pastebin.ubuntu.com/16214433/
eMMC(RAW) Boot: http://pastebin.ubuntu.com/16214420/

AM57xx-evm:
MMC Boot: http://pastebin.ubuntu.com/16214374/

Changes since v4:
- Removed unnecessary else statements.
- Fixed number of bytes read when reading u-boot image from FIT.

Changes since v3:
- Use the same function for reading the fit from FS or raw device.
