Subject: MPC8360ERDK: adapt NAND interface for the re-written FSL NAND UPM driver
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=b4fe1a71090c73efc6e4188eed188b2ff67fc02a;p=u-boot.git

MPC8360ERDK: adapt NAND interface for the re-written FSL NAND UPM driver

This patch is based on the following patch sent a few minutes ago:
"NAND FSL UPM: driver re-write using the hwcontrol callback"
It is untested, of course. Anton, could you please give it a try.
