* ppc4xx: Autocalibration can set RDCC to over aggressive value.Adam Graham2009-02-123-36/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The criteria of the AMCC SDRAM Controller DDR autocalibration U-Boot code is to pick the largest passing write/read/compare window that also has the smallest SDRAM_RDCC.[RDSS] Read Sample Cycle Select value. On some Kilauea boards the DDR autocalibration algorithm can find a large passing write/read/compare window with a small SDRAM_RDCC.[RDSS] aggressive value of Read Sample Cycle Select value "T1 Sample". This SDRAM_RDCC.[RDSS] Read Sample Cycle Select value of "T1 Sample" proves to be to aggressive when later on U-Boot relocates into DDR memory and executes. The memory traces on the Kilauea board are short so on some Kilauea boards the SDRAM_RDCC.[RDSS] Read Sample Cycle Select value of "T1 Sample" shows up as a potentially valid value for the DDR autocalibratiion algorithm. The fix is to define a weak default function which provides the minimum SDRAM_RDCC.[RDSS] Read Sample Cycle Select value to accept for DDR autocalibration. The default will be the "T2 Sample" value. A board developer who has a well defined board and chooses to be more aggressive can always provide their own board specific string function with the more aggressive "T1 Sample" value or stick with the default minimum SDRAM_RDCC.[RDSS] value of "T2". Also put in a autocalibration loop fix for case where current write/read/compare passing window size is the same as a prior window size, then in this case choose the write/read/compare result that has the associated smallest RDCC T-Sample value.

| | | | | | | | | | CONFIG_SDRAM_PPC4xx_IBM_DDR2 is not set when include/asm-ppc/config.h is included. So for katmai, CONFIG_MAX_MEM_MAPPED will get set to 256MB. It makes perfect sense to set CONFIG_MAX_MEM_MAPPED to 2GB for all PPC4xx boards right now. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | This patch adds the configuration option CONFIG_SYS_SMC_RXBUFLEN. With this option it is possible to allow the receive buffer for the SMC on 8xx to be greater then 1. In case CONFIG_SYS_SMC_RXBUFLEN == 1 this driver works as the old version. When defining CONFIG_SYS_SMC_RXBUFLEN also CONFIG_SYS_MAXIDLE must be defined to setup the maximum idle timeout for the SMC.

But we had no guarantee, and at slower bitrates, it's just over a microsecond (over 1000 clock cycles). This enforces a 2 microsecond gap between assertion and deassertion.
