155a96478a ppc4xx: Undo Sequoia patch for dynamic EBC speed support of 83MHz
This patch undoes the patch by Jeff Mann with commit-id ada4697d. As
suggested by AMCC it is not recommended to dynamically change the EBC
speed after bootup. So we undo this change to be on the safe side.

ada4697d02 [PATCH] Run new sequoia boards with an EBC speed of 83MHz
Because the Sequoia board does not boot with an EBC faster than 66MHz,
the clock divider are changed after the initial boot process.

This allows for maximum clocking speeds  to be achieved on newer boards.
Sequoia boards with 666.66 MHz processors require that the EBC divider
be set to 3 in order to start the initial boot process at a slower EBC
speed. After the initial boot process, the divider can be set back to 2,
which will cause the boards to run at 83.333MHz. This is backward
compatible with boards with 533.33 MHz processors, as these boards will
already be set with an EBC divider of 2.

f544ff6656 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.

07b7b0037a [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.

0238898382 [PATCH] Add DDR2 optimization code for Sequoia (440EPx) board
This code will optimize the DDR2 controller setup on a board specific
basis.

Note: This code doesn't work right now on the NAND booting image for the
Sequoia board, since it doesn't fit into the 4kBytes for the SPL image.
