[PATCH 0/2] mtd: rawnand: brcmnand: Glue driver Kconfig entries

[Florian Fainelli]

Hi all,

This patch series allows for a finer control over the BRCMNAND driver
glue driver selection such that it defaults to the various platforms
enabled in the configuration file.

[PATCH 1/2] mtd: rawnand: brcmnand: Move Kconfig to driver folder

[Florian Fainelli]

In preparation for allowing each of the brcmnand stub to be built
separately, move the Kconfig entry to the driver folder.

[PATCH 2/2] mtd: rawnand: brcmnand: Add individual glue driver selection

[Florian Fainelli]

Allow each platform to define a dedicated Kconfig entry for its glue
driver such that we can decide on a per-platfomr basis whether to build
it or not. This allows for a finer grained control over the resulting
kernel image or set of modules.

Miquel are you able to review and apply those patches if satisfactory? Thanks!

Sorry for the delay, I was off for almost all July/August, I need to
sync with Richard and start catching up. I'll do my best but with
LPC/ELC-E approaching, I'm far from close to have enough spare time! At
the latest, I will settle the situation right after those conferences. 

Thanks,
Miquèl

Sorry for the huge delay, I'm now trying to catch up on all my work
left since end of June, the series looks ok at a first glance and
received no comments so I'll apply it soon.

Thanks,
Miquèl
