Subject: ppc4xx: Sequoia: Remove cpu/ppc4xx/speed.c from NAND booting
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=f544ff6656fca263ed1ebe39899b6d95da67c8b8;p=u-boot.git

ppc4xx: Sequoia: Remove cpu/ppc4xx/speed.c from NAND booting

Using cpu/ppc4xx/speed.c to calculate the bus frequency is too big
for the 4k NAND boot image so define bus_frequency to 133MHz here
which is save for the refresh counter setup.
