[PATCH] Speed optimization of AMCC Sequoia/Rainier DDR2 setup
As provided by the AMCC applications team, this patch optimizes the
DDR2 setup for 166MHz bus speed. The values provided are also save
to use on a "normal" 133MHz PLB bus system. Only the refresh counter
setup has to be adjusted as done in this patch.
For this the NAND booting version had to include the "speed.c" file
from the cpu/ppc4xx directory. With this addition the NAND SPL image
will just fit into the 4kbytes of program space. gcc version 4.x as
provided with ELDK 4.x is needed to generate this optimized code.
