* ppc4xx: Reset and relock memory DLL after SDRAM_CLKTR changeAdam Graham2008-10-08-0/+21
| | | | | | | | | | | | After changing SDRAM_CLKTR phase value rerun the memory preload initialization sequence (INITPLR) to reset and relock the memory DLL. Changing the SDRAM_CLKTR memory clock phase coarse timing adjustment effects the phase relationship of the internal, to the PPC chip, and external, to the PPC chip, versions of MEMCLK_OUT.

| | | | | | | | | | This patch fixes a compilation warning for the PIP405 board. It moves the #ifndef CONFIG_CS8952_PHY define a little so that the warning doesn't occur anymore. I am a little unsure if this #ifdef is at the correct place now or if it could be removed completely. This needs to get tested on the PIP405 board. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: IBM Memory Controller DDR autocalibration routinesAdam Graham2008-09-05-0/+1212
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alternate SDRAM DDR autocalibration routine that can be generically used for any PPC4xx chips that have the IBM SDRAM Controller core allowing for support of more DIMM/memory chip vendors and gets the DDR autocalibration values which give the best read latency performance (SDRAM0_RDCC.[RDSS]). Two alternate SDRAM DDR autocalibration algoritm are provided in this patch, "Method_A" and "Method_B". DDR autocalibration Method_A scans the full range of possible PPC4xx SDRAM Controller DDR autocalibration values and takes a lot longer to run than Method_B. Method_B executes in the same amount of time as the currently existing DDR autocalibration routine, i.e. 1 second or so. Normally Method_B is used and it is set as the default method. The current U-Boot PPC4xx DDR autocalibration code calibrates the IBM SDRAM Controller registers.[bit-field]: 1) SDRAM0_RQDC.[RQFD] 2) SDRAM0_RFDC.[RFFD] This alternate PPC4xx DDR autocalibration code calibrates the following IBM SDRAM Controller registers.[bit-field]: 1) SDRAM0_WRDTR.[WDTR] 2) SDRAM0_CLKTR.[CKTR] 3) SDRAM0_RQDC.[RQFD] 4) SDRAM0_RFDC.[RFFD] and will also use the calibrated settings of the above four registers that produce the best "Read Sample Cycle Select" value in the SDRAM0_RDCC.[RDSS] register.[bit-field].

This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial.

* | ppc4xx: Rework 440GX UIC handlingStefan Roese2008-07-11-85/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Roese2008-07-11-328/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

| | | | | | | | | | | | | 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 Bruce2008-06-12-5/+5
| | | | | | | | | | | | | | | | | | | 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>
