Revert "ppc/85xx/pci: fsl_pci_init: pcie agent mode support"

2009-11-04T15:14:59Z

This reverts commit 70ed869ea5f6b1d13d7b140c83ec0dcd8a127ddc. There isn't any need to modify the API for fsl_pci_init_port to pass the status of host/agent(end-point) status. We can determine that internally to fsl_pci_init_port. Revert the patch that makes the API change. Signed-off-by: Kumar Gala

ppc/85xx/pci: fsl_pci_init: pcie agent mode support

2009-10-27T14:33:51Z

Originally written by Jason Jin and Mingkai Hu for mpc8536. When QorIQ based board is configured as a PCIe agent, then unlock/enable inbound PCI configuration cycles and init a 4K inbound memory window; so that a PCIe host can access the PCIe agents SDRAM at address 0x0 * Supported in fsl_pci_init_port() after adding pcie_ep as a param * Revamped copyright in drivers/pci/fsl_pci_init.c * Mods in 85xx based board specific pci init after this change Signed-off-by: Vivek Mahajan Signed-off-by: Kumar Gala

sbc8548: reclaim wasted sector in boot flash

2009-09-30T13:29:47Z

By nature of being based off the MPC8548CDS board, this board inherited an ENV_SIZE setting of 256k. But since it has a smaller flash device (8MB soldered on), it has a native sector size of 128k, and hence the ENV_SIZE was causing 2 sectors to be used for the environment. By removing the unused sector, we can push TEXT_BASE up closer to the end of address space and reclaim that sector for any other application. This also fixes the mismatch between TEXT_BASE and MONITOR_LEN reported by Kumar earlier. Since this board also supports the ability to boot off the 64MB SODIMM flash, this change is forward looking with that in mind; i.e. the settings for MONITOR_LEN and ENV_SIZE will work when the 512k sectors of the SODIMM flash are used for alternate boot in the future.

sbc8548: update PCI/PCI-e support code

2009-09-24T17:05:00Z

The PCI/PCI-e support for the sbc8548 was based on an earlier version of what the MPC8548CDS board was using, and in its current state it won't even compile. This re-syncs it to match the latest codebase and makes use of the new shared PCI functions to reduce board duplication. It borrows from the MPC8568MDS, in that it pulls the PCI-e I/O back to 0xe280_0000 (where PCI2 would be on MPC8548CDS), and similarly it coalesces the PCI and PCI-e mem into one single TLB. Both PCI-x and PCI-e have been tested with intel e1000 cards under linux (with an accompanying dts change in place) Signed-off-by: Paul Gortmaker Signed-off-by: Kumar Gala

sbc8548: correct local bus SDRAM size from 64M to 128M

2009-09-24T17:05:00Z

The size of the LB SDRAM on this board is 128MB, spanning CS3 and CS4. It was previously only being configured for 64MB on CS3, since that was what the original codebase of the MPC8548CDS had. In addition to setting up BR4/OR4, this also adds the TLB entry for the second half of the SDRAM. Signed-off-by: Paul Gortmaker Signed-off-by: Kumar Gala

sbc8548: use I/O accessors

2009-09-24T17:05:00Z

Sweep throught the board specific file and replace the various register proddings with the equivalent I/O accessors. Signed-off-by: Paul Gortmaker Signed-off-by: Kumar Gala

sbc8548: remove eTSEC3/4 voltage hack

2009-09-24T17:05:00Z

With only eTSEC1 and 2 being brought out to RJ-45 connectors, we aren't interested in the eTSEC3/4 voltage hack on this board Signed-off-by: Paul Gortmaker Signed-off-by: Kumar Gala

sbc8548: enable access to second bank of flash

2009-09-24T17:05:00Z

The sbc8548 has a 64MB SODIMM flash module off of CS6 that previously wasn't enumerated by u-boot. There were already BR6/OR6 settings for it [used by cpu_init_f()] but there was no TLB entry and it wasn't in the list of flash banks reported to u-boot. The location of the 64MB flash is "pulled back" 8MB from a 64MB boundary, in order to allow address space for the 8MB boot flash that is at the end of 32 bit address space. This means creating two 4MB TLB entries for the 8MB chunk, and then expanding the original boot flash entry to 64MB in order to cover the 8MB boot flash and the remainder (56MB) of the user flash.

sbc8548: cosmetic line re-wrap

2009-09-24T17:04:59Z

Fix the extra long lines to be consistent with u-boot coding style. No functional change here. Signed-off-by: Paul Gortmaker

sbc8548: get_clock_freq is not valid for this board

2009-09-24T17:04:59Z

The get_clock_freq() comes from freescale/common/cadmus.c and is only valid for the CDS based 85xx reference platforms. It would be nice if we could read the 33 vs. 66MHz status somehow, but in the meantime, tie it to CONFIG_SYS_CLK_FREQ like all the other non-CDS boards do.
