* Eliminated arch-specific mmc header requirementAndy Fleming2009-02-16-0/+191
| | | | | | | | | | The current MMC infrastructure relies on the existence of an arch-specific header file. This isn't necessary, and a couple drivers were forced to implement dummy files to meet this requirement. Instead, we move the stuff in those header files into a more appropriate place, and eliminate the stubs and the #include of asm/arch/mmc.h Signed-off-by: Andy Fleming <afleming@freescale.com>

* 86xx: Reset updatePeter Tyser2009-02-16-61/+19
| | | | | | | | | | Update the 86xx reset sequence to try executing a board-specific reset function. If the board-specific reset is not implemented or does not succeed, then assert #HRESET_REQ. Using #HRESET_REQ is a more standard reset procedure than the previous method and allows all board peripherals to be reset if needed. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* fsl-ddr: Allow system to boot if we have more than 4G of memoryKumar Gala2009-02-16-1/+1
| | | | | | | | | | Previously if we >=4G of memory and !CONFIG_PHYS_64BIT we'd report an error and hang. Instead of doing that since DDR is mapped in the lowest priority LAWs we setup the DDR controller and the max amount of memory we report back is what we can map (CONFIG_MAX_MEM_MAPPED) Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Becky Bruce <beckyb@kernel.crashing.org>

| | | | | | | | | Previously we only allowed power-of-two memory sizes and didnt handle >2G of memory. Now we will map up to CONFIG_MAX_MEM_MAPPED and should properly handle any size that we can make in the TLBs we have available to us Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* ppc4xx: Fix initialization of the SDRAM_CODT registerCarolyn Smith2009-02-12-5/+2
| | | | | | | | | This fixes the initialization of the SDRAM_CODT register in the ppc4xx DDR2 initialization code. It also removes use of the SDRAM_CODT_FEEDBACK_RCV_SINGLE_END and SDRAM_CODT_FEEDBACK_DRV_SINGLE_END #define's since they are reserved bits.

* ppc4xx: Autocalibration can set RDCC to over aggressive value.Adam Graham2009-02-12-29/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
