The command "reginfo" got an overhaul for the ppc4xx. It dumps all the relevant HW configuration registers (address, symbolic name, content). This allows to easily detect errors in *.h files and changes in the HW configuration. Signed-off-by: Niklaus Giger <niklaus.giger@member.fsf.org> Signed-off-by: Stefan Roese <sr@denx.de>
