[U-Boot] [PATCH 1/2] NAND: Make page, erase, oob size available via cmd_nand

[U-Boot] [PATCH 1/2] NAND: Make page, erase, oob size available via cmd_nand

[Marek Vasut]

The "nand info" and "nand device" now set shell/environment variables:
	nand_writesize ... nand page size
	nand_oobsize ..... nand oob area size
	nand_erasesize ... nand erase block size

The shell variables are only set if HUSH is enabled.

Also, the "nand info" command now displays this info.

[U-Boot] [PATCH 2/2] NAND: Add scrub.quiet command option

[Marek Vasut]

This allows the scrub command to scrub without asking the user if he really
wants to scrub the area. Useful in scripts.
