powerpc/85xx & 86xx: Rework ft_fsl_pci_setup to not require aliases

2010-07-20T09:40:06+00:00

Previously we used an alias the pci node to determine which node to
fixup or delete.  Now we use the new fdt_node_offset_by_compat_reg to
find the node to update.

Additionally, we replace the code in each board with a single macro call
that makes assumes uniform naming and reduces duplication in this area.

Move arch/ppc to arch/powerpc

2010-04-21T21:42:38+00:00

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.

ppc/8xxx: Delete PCI nodes from device tree if not configured

2010-04-07T05:11:39+00:00

If the PCI controller wasn't configured or enabled delete from the
device tree (include its alias).

For the case that we didn't even configure u-boot with knowledge of
the controller we can use the fact that the pci_controller pointer
is NULL to delete the node in the device tree.  We determine that
a controller was not setup (because of HW config) based on the fact
that cfg_addr wasn't setup.

ppc4xx: Fix sending type 1 PCI transactions

2010-01-23T08:27:18+00:00

The list of 4xx SoCs that should send type 1 PCI transactions
is not defined correctly. As a result PCI-PCI bridges and devices
behind them are not identified. The following 4xx variants should
send type 1 transactions: 440GX, 440GP, 440SP, 440SPE, 460EX and 460GT.

ppc/8xxx: Remove is_fsl_pci_agent

2010-01-05T19:49:07+00:00

All users of is_fsl_pci_agent have been converted to fsl_is_pci_agent
that uses the standard PCI programming model to determine host vs
agent/end-point.

fsl_pci_init_port end-point initialization is broken

2009-11-04T15:16:30+00:00

commit 70ed869e broke fsl pcie end-point initialization.
Returning 0 is not correct.  The function must return the first free
bus number for the next controller.

fsl_pci_init() must still be called and a bus allocated even if the
controller is an end-point.

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

2009-11-04T15:14:59+00:00

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.

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

2009-10-27T14:33:51+00:00

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
