dm: sandbox: pci: Add a PCI emulation uclass

2015-04-17T01:27:43+00:00

Since sandbox does not have real devices (unless it borrows those from the
host) it must use emulations. Provide a uclass which permits PCI operations
to be passed through to an emulation device.

dm: pci: Add a uclass for PCI

2015-04-17T01:27:43+00:00

Add a uclass for PCI controllers and a generic one for PCI devices. Adjust
the 'pci' command and the existing PCI support to work with this new uclass.
Keep most of the compatibility code in a separate file so that it can be
removed one day.

TODO: Add more header file comments to the new parts of pci.h

dm: pci: Move common PCI functions into their own file

2015-04-17T01:27:42+00:00

Driver model will share many functions with the existing PCI implementation.
Move these into their own file to avoid duplication and confusion.

pci: Add a function to find a device by class

2015-02-06T05:16:42+00:00

There is an existing function prototype in the header file but it is not
implemented. Implement something similar.

pci: Add functions to read and write a BAR address

2014-11-25T13:34:00+00:00

Some PCI functions cannot be auto-configured. Add a function to set up a
fixed BAR which can be used in these situations. Also add a function to read
the current address of a BAR.

pci: Honour pci_skip_dev()

2014-11-23T11:49:01+00:00

When enumerating devices, honour the pci_skip_dev() function. This can
be used by PCI controller drivers to restrict which devices will be
probed.

This is required by the NVIDIA Tegra PCIe controller driver, which will
fail with a data abort exception if an access is attempted to a device
number larger than 0 outside of bus 0. pci_skip_dev() is therefore
implemented to prevent any such accesses.

pci: add support for board_pci_fixup_dev function

2014-09-09T14:15:02+00:00

Some board-level drivers may wish to have per-device fixup functions
for PCI devices.

pci.h: allow inclusion in assembly source

2013-11-09T16:21:01+00:00

This patch simply #ifdef's out the C-specific parts of pci.h when it is
included by an assembly file. This will allow the macros it contains to
be used from assembly source as will be done in a followup commit adding
support for more modern MIPS Malta boards.
