[PATCH v5 0/8] Add rkmtd command

[Johan Jonker <jbx6244@gmail.com>]

The command rkmtd creates a virtual block device to transfer
Rockchip boot block data to and from NAND with block orientated
tools like "ums" and "rockusb".

It uses the Rockchip MTD driver to scan for boot blocks and copies
data from the first block in a GPT formatted virtual disk.
Data must be written in U-boot "idbloader.img" format and start at
partition "loader1" offset 64. The data header is parsed
for length and offset. When the last sector is received
it erases up to 5 erase blocks on NAND and writes boot blocks
in a pattern depending on the NAND ID. Data is then verified.
When a block turns out bad the block header is discarded.

Changed V5:
  Add bounce buffer flag
  Use devres_alloc in bind
  Restyle

Changed V4:
  Sort includes
  Replace constant by define
  Enable rkmtd command in sandbox defconfig
  Fix minor things in test

Changed V3:
  Add documetation
  Add test
  Split driver from command
  Split header
  Use devm_kzalloc
  Remove out of memory debug
  Restyle

Changed V2:
  Rename to rkmtd
