This is just a handy routine that reports last PCI busno: we walk
down all the hoses and return last hose's last_busno.
Will be used by PCI/PCIe initialization code.

It is no longer always true that the pci bus address can be
used as the virtual address for pci accesses. pci_map_bar()
is created to return the virtual address for a pci region.

When we search for an address match in pci_hose_{phys_to_bus,bus_to_phys}
we should give preference to memory regions that aren't system memory.
Its possible that we have over mapped system memory in the regions and
we want to avoid depending on the order of the regions.

PCI bus is inherently 64-bit. While not all system require access to
the full 64-bit PCI address range some do. This allows those systems
to enable the full PCI address width via CONFIG_SYS_PCI_64BIT.

This patch moves the check, if a device should be skipped in PCI PNP
configuration into the function pci_skip_dev(). This function is defined
as weak so that it can be overwritten by a platform specific one if
needed. The check if the device should get printed in the PCI summary upon
bootup (when CONFIG_PCI_SCAN_SHOW is defined) is moved to the function
pci_print_dev() which is also defined as weak too.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Physical addrs need to be represented by phys_addr_t, not
unsigned long. Otherwise, systems that use CONFIG_PHYS_64BIT
are going to fail mightily.

In current source code, when the device number of PCI is 0, process PCI
bridge without fail. However, when the device number is 0, it is not PCI
always bridge. There are times when device of PCI allocates.
When CONFIG_PCI_SKIP_HOST_BRIDGE is enable, this problem is solved when
use this patch.

Many users of PCI config read routines tend to ignore the function
ret value, and are only concerned about the contents of *val. Based
on this, pci_hose_read_config_{byte,word}_via_dword should initialize
the *val on dword read error.
Without this fix, for example, we'll go on scanning bus with vendor or
header_type uninitialized. This brings many unnecessary config trials.

Ensure hose->current_busno is not less than first_busno. This fixes
broken board code which leaves current_busno=0 when first_busno is
greater than 0 for the cases with multiple controllers.

Make BSS clearing on ARM systems more robust
* Patch by Yue Hu and Joe, 01 Sep 2004:
- add PCI support for ixp425;
- add EEPRO100 suppor tfor ixdp425 board.
* Fix problem with protected sector detection in driver/cfi_flash.c
fix initdram function for utx8245 board
* Patch by Markus Pietrek, 14 Apr 2004:
use ATAG_INITRD2 instead of deprecated ATAG_INITRD tag
* Patch by Reinhard Meyer, 18 Apr 2004:
provide the IDE Reset Function for EMK 5200 boards
* Patch by Masami Komiya, 12 Apr 2004:
fix pci_hose_write_config_{byte,word}_via_dword problems
- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)
* Fix alignment problems with flash driver for TRAB board
* Patch by Donald White, 21 May 2003:
fix calculation of base address in pci_hose_config_device()
* Fix bug in command line parsing: "cmd1;cmd2" is supposed to always
execute "cmd2", even if "cmd1" fails. Note that this is different
to "run var1 var2" where the contents of "var2" will NOT be
executed when a command in "var1" fails.
Add code for AmigaOne board
(preliminary merge to U-Boot, still WIP)
* Patch by Jon Diekema, 12 Nov 2002:
- Adding URL for IEEE OUI lookup
- Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
being defined.
- In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
root-on-nfs macros are designed to switch how the default boot
method gets defined.
