2015-07-28dm: pci: Correct primary/secondary/subordinate bus number assignmentBin Meng
In driver model, each pci bridge device has its own hose structure. hose->first_busno points to the bridge device's device number, so we should not substract hose->first_busno before programming the bridge device's primary/secondary/subordinate bus number registers.

2015-07-15pci: Configure expansion ROM during auto config processBin Meng
Currently PCI expansion ROM address is assigned by a call to pciauto_setup_rom() outside of the pci auto config process. This does not work when expansion ROM is on a device behind PCI bridge where bridge's memory limit register was already programmed to a value that does not cover the newly assigned expansion ROM address. To fix this, we should configure the ROM address during the auto config process.

2015-04-17dm: pci: Add a uclass for PCISimon Glass
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 Signed-off-by: Simon Glass <sjg@chromium.org>
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.

2014-11-23linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada
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 Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>

2012-09-21pci: fix some warnings related to assumptions aboutKumar Gala
The following commit introduced some warnings associated with using pci_addr_t instead of a proper 32-bit data type. commit af778c6d9e2b945ee03cbc53bb976238a3374f33 Author: Andrew Sharp <andywyse6@gmail.com> Date: Wed Aug 1 12:27:16 2012 +0000 pci: fix errant data types and corresponding access functions On some platforms pci_addr_t is defined as a 64-bit data type so its not proper to use with pci_{read,write}_config_dword.

2012-09-02pci: add CONFIG_PCI_ENUM_ONLY for platforms that don't need PCI setup doneAndrew Sharp
Introduce CONFIG_PCI_ENUM_ONLY variable for platforms that just want a quick enumberation of the PCI devices, but don't need any setup work done. This is very beneficial on platforms that have u-boot loaded by another boot loader which does a more sophisticated job of setup of PCI devices than u-boot. That way, u-boot can just read what's there and get on with life. This is what SeaBIOS does. Signed-off-by: Andrew Sharp <andywyse6@gmail.com>
2012-09-02pci: clean up some whitespace and formattingAndrew Sharp
I tried to clean up the white space and formatting offenses and inconsistencies in the generic PCI code that obviously has been around for some time. Emphasis on large increases in readability and maintainability and consistency. I omitted the platform/processor specific files in the drivers/pci directory because I wanted to leave those file to those that care more about them. Signed-off-by: Andrew Sharp <andywyse6@gmail.com>
2012-09-02pci: fix errant data types and corresponding access functionsAndrew Sharp

2010-04-21Move arch/ppc to arch/powerpcStefan Roese
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
