[U-Boot] [RFC PATCH v3 1/4] arm: iproc: add NAND driver
From: Jiandong Zheng jdzheng@broadcom.com
Add support for the iproc NAND, and enable on Cygnus and NSP boards.
Signed-off-by: Jiandong Zheng jdzheng@broadcom.com Signed-off-by: Steve Rae srae@broadcom.com --- There was a previous attempt to implement this "iproc NAND" (see: http://patchwork.ozlabs.org/patch/505399), however, due to the amount of changes required, it seemed better to implement the code in a series of steps. This is the first step, where the "iproc_nand.c" is essentially an empty file (with one function required to allow this commit to build successfully).
RFC only - more changes are coming for "drivers/mtd/nand/iproc_nand.c"
Changes in v3: - convert more CONFIG_* to Kconfig
Changes in v2: - convert some CONFIG_* to Kconfig

Why is this an RFC patch? It seems like an attempt to fix straightforward problems, unrelated to the iproc driver.

True - I'll pull it out of this series and send a new patch.
