Subject: load ixp42x NPE firmware from separate flash block, remove dead code
X-Git-Tag: v1.3.2-rc1~62^2^2~8
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=63ebcc4615dd39926ccf61f1d5f3510262ef6564;p=u-boot

load ixp42x NPE firmware from separate flash block, remove dead code

Hi,

the following patch adds support to move the IXP42X NPE firmware to a
separate flash block, whose start address is defined in
CONFIG_IXP4XX_NPE_EXT_UCODE_BASE. Using that, it is possible to build
NPE-enabled u-boot without copyright problems due to the NPE firmware.

I hope the patch applies, I get whitespace-related differences in the NPE
files due to trailing whitespace in the original versions.
