* FSL DDR: Rewrite the FSL mpc8xxx DDR controller setup code.Kumar Gala2008-08-27-0/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ppc4xx: Add 460SX UIC definesStefan Roese2008-07-11-1/+21

* | ppc4xx: Rework 440GX UIC handlingStefan Roese2008-07-11-46/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the 440GX interrupt handling so that the common 4xx code can be used. The 440GX is an exception to all other 4xx variants by having the cascading interrupt vectors not on UIC0 but on a special UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt handling is simpler without any 440GX special cases. Also some additional cleanup to cpu/ppc4xx/interrupt.c is done. Signed-off-by: Stefan Roese <sr@denx.de>
* | ppc4xx: Consolidate PPC4xx UIC definesStefan Roese2008-07-11-412/+236
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This 2nd patch now removes all UIC mask bit definition. They should be generated from the vectors by using the UIC_MASK() macro from now on. This way only the vectors need to get defined for new PPC's. Also only the really used interrupt vectors are now defined. This makes definitions for new PPC versions easier and less error prone. Another part of this patch is that the 4xx emac driver got a little cleanup, since now the usage of the interrupts is clearer. Signed-off-by: Stefan Roese <sr@denx.de>
* | ppc4xx: Consolidate PPC4xx UIC definesStefan Roese2008-07-11-28/+23
| | | | | | | | | | | | | | | | | | This patch is the first step to consolidate the UIC related defines in the 4xx headers. Move header from asm-ppc/ppc4xx-intvec.h to asm-ppc/ppc4xx-uic.h as it will hold all UIC related defines in the next steps. Signed-off-by: Stefan Roese <sr@denx.de>

* | ppc4xx: Add Mnemonics for AMCC/IBM DDR2 SDRAM ControllerGrant Erickson2008-07-11-46/+221
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch completes the preprocessor mneomics for the IBM DDR2 SDRAM controller registers (MODT and INITPLR) used by the PowerPC405EX(r). The MMODE and MEMODE registers are unified with their peer values used for the INITPLR MR and EMR registers, respectively. Finally, a spelling typo is correct (MANUEL to MANUAL). With these mnemonics in place, the CFG_SDRAM0_* magic numbers for Kilauea are replaced by equivalent mnemonics to make it easier to compare and contrast other 405EX(r)-based boards (e.g. during board bring-up). Finally, unified the SDRAM controller register dump routine such that it can be used across all processor variants that utilize the IBM DDR2 SDRAM controller core. It produces output of the form: PPC4xx IBM DDR2 Register Dump: ... SDRAM_MB0CF[40] = 0x00006701 ... which is '<mnemonic>[<DCR #>] = <value>'. The DCR number is included since it is not uncommon that the DCR values in header files get mixed up and it helps to validate, at a glance, they match what is printed in the user manual.

| | | | | | | | | | | | | | | | | | | | | | | | | | While the PowerPC 405EX(r) shares in common the AMCC/IBM DDR2 SDRAM controller core also used in the 440SP, 440SPe, 460EX, and 460GT, in the 405EX(r), SDRAM_MCSTAT has a different DCR value. Its present value on the 405EX(r) causes a read back of 0xFFFFFFFF which causes SDRAM initialization to periodically fail since it can prematurely indicate SDRAM ready status.

| | | | | | | | | | | | | | | | | | | | | | | | | | Newer PPC's like 440SPe, 460EX/GT can be equipped with more than 2GB of SDRAM. To support such configurations, we "only" map the first 2GB via the TLB's. We need some free virtual address space for the remaining peripherals like, SoC devices, FLASH etc. Note that ECC is currently not supported on configurations with more than 2GB SDRAM. This is because we only map the first 2GB on such systems, and therefore the ECC parity byte of the remaining area can't be written. Signed-off-by: Stefan Roese <sr@denx.de>

With respect to the 4xx DDR initialization and ECC unification, there is certainly more work that can and should be done (file renaming, etc.). However, that can be handled at a later date on a second or third pass. As it stands, this patch moves things forward in an incremental yet positive way for those platforms that utilize this code and the features associated with it.

There are some other locations that the name is useful (device tree setup). Expose the functionality to other bits of code. Also, drop the 'E' suffix and add it on by looking at the SVR version when we print this out. This is mainly to allow the most flexible use of the name.
