Hello,
this patch series fixes some problems on the at91sam9g45 and adds support for
flash based bad block table to the atmel nand driver.
The following changes since commit 58ec1a81a16a758bc6125f7736d13137c5b7e17f:
Merge branch 'tx25' into next (2011-02-18 11:11:48 +0100)

arch/arm/mach-at91/at91sam9g45_devices.c:101: error: 'NAND_ECC_HW' undeclared (first use in this function)

Hardware is currently not working on the at91sam9g45. So give the user a
change to specify software ecc mode.
