[U-Boot] [WIP/PATCH 0/4] unify SPI flash drivers

[Mike Frysinger]

The amount of duplication across SPI flash driver has always annoyed me,
and we've seen bugs that affect multiple drivers fixed in only some, and
I figure if the Linux kernel driver can unify these things, then there is
really no reason we can't too.

So this here are a few incremental patches to get us closer to a unified
driver.  I think the diffstat speaks for itself, and there are even more
pieces here which could possibly be merged.  But I got bored for now.

I've only lightly tested them so far with one SPI flash driver, so for
now they're not for merging.  Once I can get more testing on our side,
I'll send out a pull request.

For you adventurous/bored types, you can grab these from my sf branch:
	git://git.denx.de/u-boot-blackfin.git
Any feedback as to success/failure would be great.
