compatibility layer.

pci: Move PCI header output code into its own function

2015-12-01T13:26:37+00:00

We want to share this code with the driver model version, so put it in a
separate function.

pci: Use a separate 'dev' variable for the PCI device

2015-12-01T13:26:37+00:00

In the 'pci' command, add a separate variable to hold the PCI device. When
this code is converted to driver model, this variable will be used to hold a
struct udevice instead.

pci: Use common functions to read/write config

2015-12-01T13:26:37+00:00

Currently we use switch() and access PCI configuration via several
functions, one for each data size. Adjust the code to use generic functions,
where the data size is a parameter.

dm: pci: Reorder functions in cmd_pci.c

2015-12-01T13:26:37+00:00

Before converting this to driver model, reorder the code to avoid forward
function declarations.

pci: Refactor the pciinfo() function

2015-12-01T13:26:37+00:00

This function uses macros to output data. It seems better to use a table of
registers rather than macro-based code generation. It also reduces the
code/data size by 2KB on ARM.

pci: Use a separate variable for the bus number

2015-12-01T13:26:37+00:00

At present in do_pci(), bdf can either mean a bus number or a PCI bus number.
Use separate variables instead to reduce confusion.

dm: pci: Avoid a driver model build error with CONFIG_CMD_PCI_ENUM

2015-12-01T13:26:36+00:00

This is not supported with driver model, so print a message instead of
generating a build error. Rescanning PCI is not yet implemented.

This function will be implemented later once some additional PCI driver
model improvements are merged. It was confirmed on the mailing list
that no one on the tegra side will miss this feature, so it is disabled
for tegra.
