[U-Boot] [PATCH 0/3] Improved NAND support for mx28evk
This patchset improves the mx28evk default environment so it is easier to use by users when testing the NAND support.
It provides a set of new environment routines as:
- update_nand_kernel - update_nand_fdt - update_nand_filesystem
and allow for easy NAND boot using:
'run nandboot'
This has been tested using:
Samsung 4G NAND, part-#: K9LBG08U0D-PCB0
Otavio Salvador (3): mx28evk: Use 512k for fdt partition to align it mx28evk: Add 'nandboot' environment command mx28evk: Extend environment to easy write of NAND system

Using 512k for fdt partition allow it to be aligned with the other small partitions and 512k erase block size.

This reads the kernel, ftd and boot into ubifs filesystem. While on that, the SD firmware filename definition has been moved next to the other SD related commands.

This adds following new targets:
- update_nand_kernel - update_nand_fdt - update_nand_filesystem
and to avoid confusion, the 'update_nand_full' has been renamed to 'update_nand_firmware_full'.
