Sascha Hauer e6b8bdc0c5 cfi_flash: move include/cfi_flash.c next to driver 
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.

Marc Kleine-Budde 1e658639f1 cfi_flash: fix alignment problem 
This patch fixes a alignment problem which may show during this
scenario:
- 32 or 64 attached NOR flash
- flashing an image directly from network to the nor flash

The involved network driver is "smc9111.c".

The data that comes from the network stack and should be written into
the flash isn't 32 bit alligned (at least with this network driver).
This is probably due to the 48 bit wide ethernet addresses.

However the "cfi_flash.c" driver doesn't handle this situation, and
accesses the not-alligned address with a 32 bit pointer.

This patch fixes the problem by reducing the access width if an
alligment problem between source and destination is found.

Matthias Kaehlcke b36552fafd New CFI flash driver: Fix misleading trace when unprotecting a sector 
When (un)protecting a flash sector with the new CFI flash driver a trace
"protect 0x..." is generated, independently of the type of operation. This is
misleading in case of an unprotect. Tell the truth when unprotecting a sector.

	xargs -0 -r rename 's/u[-_]?boot/barebox/'

It needs some manual fixup following in the next patch
