* 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: PPC44x MQ initializationYuri Tikhonov2008-10-17-4/+6
|/ | | | | | | | | | | | | | | | | | | Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC values. This fixes the occasional 440SPe hard locking issues when the 440SPe's dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver). Previously the appropriate initialization had been made in Linux, by the ppc440spe ADMA driver, which is wrong because modifying the MQ configuration registers after normal operation has begun is not supported and could have unpredictable results. Comment from Stefan: This patch doesn't change the resulting value of the MQ registers. It explicitly sets/clears all bits to the desired state which better documents the resulting register value instead of relying on pre-set default values.

| | | | | | | | | | | | | This patch fixes some minor issues introduced with the patch: ppc4xx: Optimize PLB4 Arbiter... from Prodyut Hazarika: - Rework memory-queue and PLB arbiter optimization code, that the local variable is not needed anymore. This removes one #ifdef. - Use consistant spacing in ppc4xx.h header (XXX + 0x01 instead of XXX+ 0x01). This was not introduced by Prodyut, just a copy-paste problem.

* ppc4xx: Add Mnemonics for AMCC/IBM DDR2 SDRAM ControllerGrant Erickson2008-07-11-165/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ppc4xx: Enable support for > 2GB SDRAM on AMCC KatmaiStefan Roese2008-07-10-11/+45
| | | | | | | | | | | | | 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>
* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-2/+2
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
* ppc4xx: Change Kilauea to use the common DDR2 init functionStefan Roese2008-06-03-0/+11
| | | | | | | | | | | This patch changes the kilauea and kilauea_nand (for NAND booting) board port to not use a board specific DDR2 init routine anymore. Now the common code from cpu/ppc4xx is used.

* ppc4xx: Enable Primordial Stack for 40x and Unify ECC HandlingGrant Erickson2008-06-03-4/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (Part 1 of 2): * Rolls up a suite of changes to enable correct primordial stack and global data handling when the data cache is used for such a purpose for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS). * Related to the first, unifies DDR2 SDRAM and ECC initialization by eliminating redundant ECC initialization implementations and moving redundant SDRAM initialization out of board code into shared 4xx code. * Enables MCSR visibility on the 405EX(r). * Enables the use of the data cache for initial RAM on both AMCC's Kilauea and Makalu and removes a redundant CFG_POST_MEMORY flag from each board's CONFIG_POST value. - Removed, per Stefan Roese's request, defunct memory.c file for Makalu and rolled sdram_init from it into makalu.c. 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.

* ppc4xx: Update Katmai/44x_spd_ddr2.c code for optimal DDR2 setupStefan Roese2008-01-05-15/+37
| | | | | | | | | | | | | | On Katmai the complete auto-calibration somehow doesn't seem to produce the best results, meaning optimal values for RQFD/RFFD. This was discovered by GDA using a high bandwidth scope, analyzing the DDR2 signals. GDA provided a fixed value for RQFD, so now on Katmai "only" RFFD is auto-calibrated. This patch also adds RDCC calibration as mentioned on page 7 of the AMCC PowerPC440SP/SPe DDR2 application note: "DDR1/DDR2 Initialization Sequence and Dynamic Tuning" Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add CONFIG_4xx_DCACHE compile options to enable cached SDRAMStefan Roese2007-10-31-2/+2
| | | | | | | | | | | | | | This patch adds the CONFIG_4xx_DCACHE options to some SDRAM init files and to the Sequoia TLB init code. Now the cache can be enabled on 44x boards by defining CONFIG_4xx_DCACHE in the board config file. This option will disappear, when more boards use is successfully and no more known problems exist. This is tested successfully on Sequoia and Katmai. The only problem that needs to be fixed is, that USB is not working on Sequoia right now, since it will need some cache handling code too, similar to the 4xx EMAC driver.

* [PATCH] PPC4xx: Add 440SP(e) DDR2 SPD DIMM supportStefan Roese2007-02-20-0/+2759
This patch adds support for the DDR2 controller used on the 440SP and 440SPe. It is tested on the Katmai (440SPe) eval board and works fine with the following DIMM modules: - Corsair CM2X512-5400C4 (512MByte per DIMM) - Kingston ValueRAM KVR667D2N5/512 (512MByte per DIMM) - Kingston ValueRAM KVR667D2N5K2/2G (1GByte per DIMM) This patch also adds the nice functionality to dynamically create the TLB entries for the SDRAM (tlb.c). So we should never run into such problems with wrong (too short) TLB initialization again on these platforms. Signed-off-by: Stefan Roese <sr@denx.de>
