* fsl-ddr: Fix handling of >4G of memory when !CONFIG_PHYS_64BITKumar Gala2009-06-12-1/+1
| | | | | | | | | | | | | | | The ddr code computes most things as 64-bit quantities and had some places in the middle that it was using phy_addr_t and phys_size_t. Instead we use unsigned long long through out and only at the last stage of setting the LAWs and reporting the amount of memory to the board code do we truncate down to what we can cover via phys_size_t. This has the added benefit that the DDR controller itself is always setup the same way regardless of how much memory we have. Its only the LAW setup that limits what is visible to the system.

* Pass dimm parameters to populate populate controller optionsHaiying Wang2008-10-18-1/+2
| | | | | | | | | | | | | Because some dimm parameters like n_ranks needs to be used with the board frequency to choose the board parameters like clk_adjust etc. in the board_specific_paramesters table of the board ddr file, we need to pass the dimm parameters to the board file. * move ddr dimm parameters header file from /cpu to /include directory. * add ddr dimm parameters to populate board specific options. * Fix fsl_ddr_board_options() for all the 8xxx boards which call this function.

* FSL DDR: Rewrite the FSL mpc8xxx DDR controller setup code.Kumar Gala2008-08-27-0/+80
The main purpose of this rewrite it to be able to share the same initialization code on all FSL PowerPC products that have DDR controllers. (83xx, 85xx, 86xx). The code is broken up into the following steps: GET_SPD COMPUTE_DIMM_PARMS COMPUTE_COMMON_PARMS GATHER_OPTS ASSIGN_ADDRESSES COMPUTE_REGS PROGRAM_REGS This allows us to share more code an easily allow for board specific code overrides. Additionally this code base adds support for >4G of DDR and provides a foundation for supporting interleaving on processors with more than one controller.
