* 85xx: Fix address map for 36-bit config of MPC8572DSKumar Gala2009-02-16-3/+6
| | | | | | | | | | When we introduced the 36-bit config of the MPC8572DS board we had the wrong PCI MEM bus address map. Additionally, the change to the address map exposes a small issue in our dummy read on the ULI bus. We need to use the new mapping functions to handle that read properly in the 36-bit config.

| | | | | | | | | 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: Autocalibration can set RDCC to over aggressive value.Adam Graham2009-02-12-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | 82xx, mgcoge: fix compile errorHeiko Schocher2009-02-12-0/+1

| | | | | | | | | | Now that the rest of u-boot can support it, change the PCI bus address of the PCI MEM regions from 0x80000000 to 0xc0000000, and use the same bus address for both PCI1 and PCI2.

Also, remove the BL_xxx defines that were only used by the alaska board, and switch to using the BATU_BL_xxx defines used by all the other boards.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | include/flash.h was commented to say that the address in flash_info->start was a physical address. However, from u-boot's point of view, and looking at most flash code, it makes more sense for this to be a virtual address. So I corrected the comment to indicate that this was a virtual address. The only flash driver that was actually treating the address as physical was the mtd/cfi_flash driver. However, this code was using it inconsistently as it actually directly dereferenced the "start" element, while it used map_physmem to get a virtual address in other places. I changed this driver so that the code which initializes the info->start field calls map_physmem to get a virtual address, eliminating the need for further map_physmem calls. The code is now consistent. The *only* place a physical address should be used is when defining the flash banks list that is used to initialize the flash_info struct, usually found in the board config file.
