Subject: [PATCH v4 00/11] mtd: nand: add Broadcom NAND controller support

Hi,

This is the fourth (and final?) version of support for the Broadcom BCM7xxx
Set-Top Box NAND controller. This controller has been used in a variety of
Broadcom SoCs.

Tested to work on Cygnus, BCM7445, and BCM63138.

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

v3 -> v4:
 * move to brcmnand/ subdirectory
 * add MAINTAINERS entry
 * fixup endianness issues (only use __raw_xxx on MIPS BE)
 * split core NAND support into library, with tiny platform drivers for STB
   (BCM7xxx), iProc, and BCM63138
 * restructure DT binding, so all SoC extras become part of main controller
   node
