2015-02-16PCI: add 64-bit prefetchable memory supportDavid Feng
PCI specification allow prefetchable memory to be 32-bit or 64-bit. PCI express specification states that all memmory bars for prefetchable memory must be implemented as 64-bit. They all require that 64 bit prefetchble memory are suported especially when u-boot is ported to more and more 64bit processors.

2014-11-25pci: Add general support for execution of video ROMsSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>

2014-11-23pci: Honour pci_skip_dev()Thierry Reding
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.

Many of references of those macros must be fixed to suppress warnings.

2013-11-09malta: support for coreFPGA6 boardsPaul Burton
This patch adds support for running on Malta boards using coreFPGA6 core cards, including support for the msc01 system controller used with them. The system controller is detected at runtime allowing one U-boot binary to run on a Malta with either. Due to the PCI I/O base differing between Maltas using gt64120 & msc01 system controllers, the UART setup is modified slightly. A second UART is added so that there is one pointing at the correct address for each system controller. The Malta board then defines its own default_serial_console function to select the correct one at runtime. The incorrect UART will simply not function. Tested on: - A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both with and without an L2 cache. - QEMU. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

configuration space. Previously, the address of a requested capability is define like that "#define PCI_DCR 0x78" But, the addresses of capabilities is different with regard to PCIe revs. So this method is not flexible. Now a function to get the address of a requested capability is added and used. It can get the address dynamically by capability ID. The step of this function: 1. Read Status register in PCIe configuration space to confirm that Capabilities List is valid. 2. Find the address of Capabilities Pointer Register. 3. Find the address of requested capability from the first capability. Signed-off-by: Zhao Qiang <B45475@freescale.com>

Move Freescale specific register define to arch/powerpc/include/asm/fsl_pci.h and update the register offset define for T4240. 2. add the status/control register define use status/control register to judge the link status 3. The original code uses 'Programming Interface' field to judge if PCIE is EP or RC mode, however, T4240 does not support this functionality. According to PCIE specification, 'Header Type' offset 0x0e is used to indicate header type, so for PCIE controller, the patch changes code to use 'Header Type' field to identify if the PCIE is RC or EP mode.
