* | ppc4xx: Undo Sequoia patch for dynamic EBC speed support of 83MHzStefan Roese2007-06-01-6/+0
| | | | | | | | | | | | | | | | 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. Signed-off-by: Stefan Roese <sr@denx.de>
* | [PATCH] Run new sequoia boards with an EBC speed of 83MHzJeffrey Mann2007-05-16-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Jeffrey Mann <mannj@embeddedplanet.com>
* | ppc4xx: Sequoia: Remove cpu/ppc4xx/speed.c from NAND bootingStefan Roese2007-05-05-1/+9
|/ | | | | | | | 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. Signed-off-by: Stefan Roese <sr@denx.de>

* | [PATCH] Speed optimization of AMCC Sequoia/Rainier DDR2 setupStefan Roese2007-03-06-8/+13
|/ | | | | | | | | | | | | | 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.

|/ | | | | | | | | | 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. Signed-off-by: Stefan Roese <sr@denx.de>

- Add support for PPC440EPx & PPC440GRx - Add support for PPC440EP(x)/GR(x) NAND controller in cpu/ppc4xx directory - Add NAND boot functionality for Sequoia board, please see doc/README.nand-boot-ppc440 for details - This Sequoia NAND image doesn't support environment in NAND for now. This will be added in a short while. Patch by Stefan Roese, 07 Sep 2006
