pci: tegra: Add Tegra PCIe driver

2014-12-18T20:19:20+00:00

Add support for the PCIe controller found on some generations of Tegra.
Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has 3 root
ports with a total of 6 lanes and Tegra124 has 2 root ports with a total
of 5 lanes.

This is based on the Linux kernel driver, originally submitted upstream
by Mike Rapoport.

The patch changes PCIe dts node status to 'disabled' if the
corresponding controller is disabled according to serdes protocol.

pci: Add general support for execution of video ROMs

2014-11-25T14:11:14+00:00

Some platforms don't have native code for dealing with their video
hardware. In some cases they use a binary blob to set it up and perform
required actions like setting the video mode. This approach is a hangover
from the old PC days where a ROM was provided and executed during startup.

Even now, these ROMs are supplied as a way to set up video. It avoids the
code for every video chip needing to be provided in the boot loader. But
it makes the video much less flexible - e.g. it is not possible to do
anything else while the video init is happening (including waiting hundreds
of milliseconds for display panels to start up).

In any case, to deal with this sad state of affairs, provide an API for
execution of x86 video ROMs, either natively or through emulation.

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.

linux/kernel.h: sync min, max, min3, max3 macros with Linux

2014-11-23T11:48:30+00:00

U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does.  This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
 - Use min, max, min3, max3 only when the arguments have the same type
   (or add casts to the arguments)
 - Use min_t/max_t instead with the appropriate type for the first
   argument
