* | powerpc/8xxx: Fix possible compile issue related to P1013Kumar Gala2011-02-04-1/+1
| | | | | | | | | | | | | | | | | | The P1013 is a single core version of P1022 and thus should use the p1022_serdes.c code. It was acciently pointing to p1013_serdes.c which doesn't exist. Reported-by: Renaud Barbier <renaud.barbier@ge.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* | powerpc/mpc85xx: implement workaround for errata DDR111 and DDR134York Sun2011-02-03-1/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | Workaround for the following errata: DDR111 - MCKE signal may not function correctly at assertion of HRESET DDR134 - The automatic CAS-to-Preamble feature of the DDR controller can calibrate to incorrect values These two workarounds must be implemented together because they touch common registers.

* mpc85xx: Enable unique mode registers and dynamic ODT for DDR3York Sun2011-01-19-54/+512
| | | | | | | | | | | | | | | | | | Added fsl_ddr_get_version() function to for DDR3 to poll DDRC IP version (major, minor, errata) to determine if unique mode registers are available. If true, always use unique mode registers. Dynamic ODT is enabled if needed. The table is documented in doc/README.fsl-ddr. This function may also need to be extend for future other platforms if such a feature exists. Enable address parity and RCW by default for RDIMMs. Change default output driver impedance from 34 ohm to 40ohm. Make it 34ohm for quad-rank RDIMMs. Use a formula to calculate rodt_on for timing_cfg_5. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* mpc85xx: Adding more registers and optionsYork Sun2011-01-19-3/+9
| | | | | | | | | | | | | This patch exposes more registers which can be used by the DDR drivers or interactive debugging. U-boot doesn't use all the registers in DDRC. When advanced tuning is required, writing to those registers is needed. Add writing to cdr1, cdr2, err_disable, err_int_en and debug registers Add options to override rcw, address parity to RDIMMs. Use array for debug registers.

* powerpc/8xxx: Add hwconfig APIs to address early parsing used by DDR initKumar Gala2011-01-19-19/+59
| | | | | | | | | | | | | | | | | | | | | | | | | There are several users of the hwconfig APIs (8xxx DDR) before we have the environment properly setup. This causes issues because of the numerous ways the environment might be accessed because of the non-volatile memory it might be stored in. Additionally the access might be so early that memory isn't even properly setup for us. Towards resolving these issues we provide versions of all the hwconfig APIs that can be passed in a buffer to parse and leave it to the caller to determine how to allocate and populate the buffer. We use the _f naming convention for these new APIs even though they are perfectly useable after relocation and the environment being ready. We also now warn if the non-f APIs are called before the environment is ready to allow users to address the issues. Finally, we convert the 8xxx DDR code to utilize the new APIs to hopefully address the issue once and for all. We have the 8xxx DDR code create a buffer on the stack and populate it via getenv_f().

* powerpc/8xxx: Refactor SRIO initialization into common codeKumar Gala2011-01-14-3/+122
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Moved the SRIO init out of corenet_ds and into common code for 8xxx/QorIQ processors that have SRIO. We mimic what we do with PCIe controllers for SRIO. We utilize the fact that SRIO is over serdes to determine if its configured or not and thus can setup the LAWs needed for it dynamically. We additionally update the device tree (to remove the SRIO nodes) if the board doesn't have SRIO enabled. Introduced the following standard defines for board config.h: CONFIG_SYS_SRIO - Chip has SRIO or not CONFIG_SRIO1 - Board has SRIO 1 port available CONFIG_SRIO2 - Board has SRIO 2 port available (where 'n' is the port #) CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup) CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup) [ These mimic what we have for PCI and PCIe controllers ] Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Wolfgang Denk <wd@denx.de>

* mpc85xx boards: initdram() cleanup/bugfixBecky Bruce2011-01-14-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct initdram to use phys_size_t to represent the size of dram; instead of changing this all over the place, and correcting all the other random errors I've noticed, create a common initdram that is used by all non-corenet 85xx parts. Most of the initdram() functions were identical, with 2 common differences: 1) DDR tlbs for the fixed_sdram case were set up in initdram() on some boards, and were part of the tlb_table on others. I have changed them all over to the initdram() method - we shouldn't be accessing dram before this point so they don't need to be done sooner, and this seems cleaner. 2) Parts that require the DDR11 erratum workaround had different implementations - I have adopted the version from the Freescale errata document. It also looks like some of the versions were buggy, and, depending on timing, could have resulted in the DDR controller being disabled. This seems bad. The xpedite boards had a common/fsl_8xxx_ddr.c; with this change only the 517 board uses this so I have moved the ddr code into that board's directory in xpedite517x.c Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org> Tested-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* mpc85xx/tlb.c: Allow platforms to specify wimge bitsBecky Bruce2011-01-14-1/+5
| | | | | | | | | | | | | Some platforms might want to override the default wimge=0 for DDR. Add CONFIG_SYS_PPC_DDR_WIMGE for those platforms to use. This will initially only be used by TQM85xx, but could be useful for other boards or testing going forward. Note that the name of this define is not 85xx-specific. WIMGE is a fairly universal concept, so any ppc platforms that require different WIMGE settings for DDR can use the same #define.
