[PATCH v3 00/10] mtd: nand: add Broadcom NAND controller support

Hi,

This is version 3 of support for the Broadcom BCM7xxx Set-Top Box NAND
controller. This controller has been used in a variety of Broadcom SoCs.

This series now adds support for a few new chips: BCM63138, and the iProc chip
family. These add an additional 6 new patches to the original 4. If the only
comments end up on the latter 6 patches, the first 4 might be worth merging
independently.

Summary changelog:

v1 -> v2:
* add NAND to DTS for BCM7445 / BCM97445SVMB
* rename DT binding file to have 'brcm,' prefix
* catch DMA mapping errors
* fixup timeout / error messages (hex, remove misleading info)
* MODULE_LICENSE("GPL v2")
* fix incorrect comments
* print why we fail, when checking for supported controller revisions
* disable prefetch when using Flash DMA (see FIXME); will re-enable once we
get a good erased-page verification scheme merged

v2 -> v3:
* rebase to v4.1-rc1
* add SoC-specific infrastructure, to help support other SoCs:
- add BCM63138 support
- add iProc/Cygnus support
* disable prefetch on v6.1
