Subject: omap3 beagle: nand (mostly) cleanups
X-Git-Tag: v2.6.27-omap1~258
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=05c19c4a970bb1a65266e75882dd79bb398bbd75;p=linux-2.6-omap-h63xx.git

omap3 beagle: nand (mostly) cleanups

Clean up the Beagle NAND config a bit:  use SZ_128K instead of
an arithmetic expression for the NAND block size.  Set the
NAND_BUSWIDTH_16 flag.  Make its init routine static.

(Unrelated:  make omap3_beagle_i2c_init be part of beagle_init.
It shouldn't be called on non-beagle hardware; and beagle_init
already runs with other arch_initcall code.)
