[U-Boot] [PATCH 00/08 V2] Allow PCI bus address, PA, and VA to differ

[U-Boot] [PATCH 00/08 V2] Allow PCI bus address, PA, and VA to differ

[Becky Bruce]

This is resubmit of a series I sent back in December - I've
rebased to the latest tree and split out a couple of the patches
as requested.

This patch series cleans up much of the VA/PA/PCI bus address confusion
that is is currently causing a couple of problems on the 8641 36-bit
port, and was preventing us from having a PCI mem bus address that
differed from the virtual address of the region.

I have fixed a number of problems, such as the ahci driver directly
using the pci BAR setting as a virtual address and pci window
mapping overlap.  There's also some cleanup to the BAT code that
were needed to make some of this cleaner.

Cheers,
Becky

[U-Boot] [PATCH 1/8] mpc8641hpcn: Set up outbound pci windows before inbound

[Becky Bruce]

Because the inbound pci windows are mapped generously, set up
the more specific outbound windows first.  This way, when we
search the pci regions for something, we will hit on the more
specific region.  This can actually be a problem on systems
with large amounts of RAM.

[U-Boot] [PATCH 2/8] drivers/pci: Create pci_map_bar function

[Becky Bruce]

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.

[U-Boot] [PATCH 3/8] powerpc: Move duplicated BAT defines to mmu.h

[Becky Bruce]

The BAT fields are architected; there's no need for these to be in
cpu-specific files.  Drop the duplication and move these to
include/asm-ppc/mmu.h.  Also, remove the BL_xxx defines that were only
used by the alaska board, and switch to using the BATU_BL_xxx defines
used by all the other boards.  The BL_ defines previously in use
had to be shifted into the proper position for use, which was inefficient.

If CONFIG_ADDR_MAP is enabled, update the address map
whenever we write a bat.

[U-Boot] [PATCH 5/8] mpc8641hpcn: Clean up PCI mapping concepts

[Becky Bruce]

Clean up PCI mapping concepts in the 8641 config - rename _BASE
to _BUS, as it's actually a PCI bus address, separate virtual
and physical addresses into _VIRT and _PHYS, and use each
appopriately.

[U-Boot] [PATCH 8/8] mpc8641hpcn: Change PCI MEM pci bus address

[Becky Bruce]

Now that the rest of u-boot can support it, change the PCI bus
address of the PCI MEM regions from 0x80000000 to 0xc0000000,
and use the same bus address for both PCI1 and PCI2.  This will
maximize the amount of PCI address space left over to map RAM
on systems with large amounts of memory.

[U-Boot] 86xx maintainership change?

Do we just want to elect Andy maintainer for 86xx as well?  He's  
already handling generic 85xx/86xx common stuff.  Seeing as there  
isn't much 86xx work going on at this point doesn't seem like that  
much more.
