These are a number of assorted upstream Linux fixes to the
BRCMNAND driver that I have backported in an attempt to get
BRCMBCA working with U-Boot (still not there).

This patch set lowers the hamming distance between the Linux
and U-Boot drivers a bit as well, while we deviate quite
a bit it is still possible to bring fixes over thanks to
exercises like this.

On top of this I have a BCMBCA driver which works fine
albeit with some complaints about ONFI:

NAND:  Could not find valid ONFI parameter page; aborting
256 MiB
(...)
=> nand info

Device 0: nand0, sector size 128 KiB
  Page size         2048 b
  OOB size            64 b
  Erase size      131072 b
  ecc strength         4 bits
  ecc step size      512 b
  subpagesize       2048 b
  options       0x00104200
  bbt options   0x00060000

Changes in v2:
- Augment the write protect handling to also support the bool
  "write-protect" property in legacy DTS files.
- Fix a mistake in the use_strap DTS property parsing.
- Tested successfully with BCMBCA driver (will be submitted
  once this is merged).
- Link to v1: https://patchwork.ozlabs.org/project/uboot/list/?series=423357
