Hi all,
Here are some patches to clean up the confusion between cfi_flash.c and
cfi_flash_new.c. First of all, fix the new driver for Intel Chips, do
some general cleanup and finally remove the old driver. The way the
kconfig variables are defined all defconfigs should switch to the
new driver automatically.
Sascha

There was some mixup when to to a full status check and
when to do a status check only. Fix this.

* [PATCH 6/6] cfi_flash: move include/cfi_flash.c next to driver
2010-02-08 13:47 ` [PATCH 5/6] cfi_flash: remove old driver and switch to new one Sascha Hauer

To: barebox
This file has no useful things for others than the driver,
so move it next to the driver and remove the corresponding
include from other files.
