| | | | | | | | | | fixes breakeage introduced by commit a37c36f4e70bada297f281b0e542539ad43e50f6 "powerpc/8xxx: query feature reporting register for num cores on unknown cpus" Reported-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/8xxx: query feature reporting register for num cores on unknown cpusKim Phillips2010-08-01-2/+8
| | | | | | | | | | doing so helps avant garde users, such as those using simulators that allow users to configure the number of cores, so as to not have to manually adjust u-boot sources. h/w should also be reliably setting FRR NCPU in the future.

* powerpc/8xxx: Improvement to DDR parametersyork2010-07-26-7/+8
| | | | | | Changes for P2020DS DDR applies to other 8xxx platform Signed-off-by: York Sun <yorksun@freescale.com>
* powerpc/8xxx: Enable DDR3 RDIMM supportyork2010-07-26-53/+55
| | | | | | | | | Enabled registered DIMMs using data from SPD. RDIMMs have registers which need to be configured before using. The register configuration words are stored in SPD byte 60~116 (JEDEC standard No.21-C). Software should read those RCWs and put into DDR controller before initialization.

* powerpc/8xxx: Enable quad-rank DIMMs.york2010-07-26-21/+60
| | | | | | | Previous code presumes each DIMM has up to two rank (chip select). Newer DDR controller supports up to four chip select on one DIMM. Signed-off-by: York Sun <yorksun@freescale.com>

The syntax is setenv hwconfig "fsl_ddr:ctlr_intlv=<mode>,bank_intlv=<mode>" The mode values for memory controller interleaving are cacheline page bank superbank The mode values for bank interleaving are cs0_cs1 cs2_cs3 cs0_cs1_and_cs2_cs3 cs0_cs1_cs2_cs3 Signed-off-by: York Sun <yorksun@freescale.com>

* powerpc 83xx/85xx: Merge lbc upmconfig codeBecky Bruce2010-07-16-0/+50
| | | | | | | | | | Each platform had its own version of the upmconfig, despite the init process being identical. Now that we have a spot for common lbc code, create a common upmconfig() there.

* 83xx/85xx/86xx: LBC register cleanupBecky Bruce2010-07-16-0/+85
| | | | | | | | | | | | | | | | | | | | | Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

* mpc8xxx: Remove cpu-handles for cpus we deleteKumar Gala2010-07-16-6/+30
| | | | | | | We may have cpu-handles pointing to the cpu nodes we delete. If so we should delete the handles as well. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | CONFIG_SYS_FSL_SEC_COMPAT is set to 2 for the SEC 2.x and SEC 3.x. Parts with newer SEC h/w versions will increment the number to accomodate incompatible code changes. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Enabled support for Rev 1.3 SPD for DDR2 DIMMsYork Sun2010-05-12-2/+2
| | | | | | | | | | | | | | SPD has minor change from Rev 1.2 to 1.3. This patch enables Rev 1.3. The difference has ben examined and the code is compatible. Speed bins is not verified on hardware for CL7 at this moment. This patch also enables SPD Rev 1.x where x is up to "F". According to SPD spec, the lower nibble is optionally used to determine which additinal bytes or attribute bits have been defined. Software can safely use defaults. However, the upper nibble should always be checked. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx/mpc8536ds: Use is_serdes_configured() to determine of PCIe enabledKumar Gala2010-05-12-12/+0
| | | | | | | | | | | | The new is_serdes_configured covers a broader range of devices than the PCI specific code. Use it instead as we convert away from the is_fsl_pci_cfg() code. Additionally move to setting LAWs for PCI based on if its configured. Also updated PCI FDT fixup code to remove PCI controllers from dtb if they are configured.

* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-0/+4421
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
