x86: Remove HAVE_ACPI_RESUME

2015-12-09T09:44:56Z

These are currently dead codes. Until we have complete ACPI support, we don't know if it works or not. Remove to avoid confusion. Signed-off-by: Bin Meng Acked-by: Simon Glass Tested-by: Simon Glass

dm: pci: Disable PCI compatibility functions by default

2015-12-01T13:26:38Z

We eventually need to drop the compatibility functions for driver model. As a first step, create a configuration option to enable them and hide them when the option is disabled. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: pci: Move common auto-config functions to a common file

2015-12-01T13:26:37Z

Some functions will be used by driver model and legacy PCI code. To avoid duplication, put these in a separate, shared file. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: pci: Rename pci_auto.c to pci_auto_old.c

2015-12-01T13:26:37Z

This file should not be used with driver model as it has lots of legacy/ compatibility functions. Rename it to make this clear. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: tegra: pci: Convert tegra boards to driver model for PCI

2015-12-01T13:26:36Z

Adjust the Tegra PCI driver to support driver model and move all boards over at the same time. This can make use of some generic driver model code, such as the range-decoding logic. Signed-off-by: Simon Glass Tested-by: Stephen Warren

dm: pci: Add a function to find the regions for a PCI bus

2015-12-01T13:26:36Z

This function looks up the controller and returns a pointer to each region type. Signed-off-by: Simon Glass Acked-by: Stephen Warren Tested-by: Stephen Warren

dm: pci: Add a function to get the controller for a bus

2015-12-01T13:26:36Z

A PCI bus may be a bridge device where the controller is the bridge's parent. Add a function to return the controller device, given a PCI device. Signed-off-by: Simon Glass Acked-by: Stephen Warren Tested-by: Stephen Warren

dm: pci: Add functions to emulate 8- and 16-bit access

2015-12-01T13:26:36Z

Provide a few functions to support using 32-bit access to emulate 8- and 16-bit access. Signed-off-by: Simon Glass Reviewed-by: Stephen Warren Tested-by: Stephen Warren

dm: pci: Support decoding ranges with duplicate entries

2015-12-01T13:26:36Z

At present we add a new resource entry for every range entry. But some range entries refer to configuration regions. To make this work, avoid adding two regions of the same type. The later ranges will overwrite the earlier (configuration) ones. There does not seem to be a way to distinguish the configuration ranges other than by ordering (as per the device tree binding). We could perhaps instead just store one region of each type in a simple array. Once we are sure that we don't need to support multiple regions, we could change this. It would be easier to do it when all drivers are converted to use driver model for PCI. Signed-off-by: Simon Glass Tested-by: Stephen Warren

dm: pci: Set up the SDRAM mapping correctly

2015-12-01T13:26:36Z

SDRAM doesn't always start at 0. Adjust the region mapping so that it works on platforms where SDRAM is somewhere else. This needs testing on other platforms. Signed-off-by: Simon Glass Tested-by: Stephen Warren
