[PATCH] ARM: Samsung: Add platform support code for OneNAND controller
Marek Szyprowski
m.szyprowski at samsung.com
Thu May 20 02:59:05 EDT 2010
This patch adds setup code for Samsung OneNAND controller driver. The
driver needs to be aware on which SoC it is running, so the actual
device id is being changed in cpu init code. S3C64xx SoCs have 2 OneNAND
controllers while S5PC100 and S5PC110 has only one.

The patch has been prepared in assumtion that the plat-s5pc1xx cleanup
patches has been applied as well as "Add support for Samsung Aquila
board (S5PC110 based)" patch series.
The driver itself has been merged by mtd maintainers, but without the
platform setup code it is useless.
Changes sinve v2:
* rebased onto git://git.fluff.org/bjdooks/linux for-linus/samsung4
Changes since v1:
* addressed all coding style issues reported by Ben
* moved all resource definitions to platform device resources
* moved all resource definitions for different SoCs from regs-onenand.h to
arch/arm/mach-{s3c64xx,s5pc100,s5pv210}/include/mach/map.h
* moved all #ifdef conditional code to separate functions
Changes since first submission attempt (long time ago):
* all cpu conditional code in the driver has been redesigned from cpu_is_xxx()
macros to actual device ids.
The Samsung OneNAND driver itself has been posted also to the Linux MTD
mailing list (linux-mtd at lists.infradead.org).
