ARM RealView PB11MPCore (7) Bootloader

u-boot

• How to port u-boot to a new platform

Scenario
Project Name: realview_pb11mp

ARCH: arm
CPU: armct_rv

Board Name: realview_pb

Porting Procedure

In Brief :
[ ]# wget http://ftp.denx.de/pub/u-boot/u-boot-1.3.1.tar.bz2
[ ]# wget u-boot-mpcore.patch.gz
[ ]# tar jxvf u-boot-1.3.1.tar.bz2
[ ]# mv u-boot-1.3.1 u-boot-1.3.1-mpcore
[ ]# cd u-boot-1.3.1-mpcore
[ ]# zcat ../u-boot-mpcore.patch.gz | patch -p1
[ ]# make realview_pb11mp_config
[ ]# make
[ ]# cp u-boot u-boot.axf

In Detail :

Affected directories in porting a new ARM processor design are:
board, cpu, include, and lib_arm. (and maybe drivers) All other directories remain the same for any architectures.
