[PATCH 0/6] Fixes for Forth PCI config access words and implementation

[Mark Cave-Ayland]

This series provides a set of fixes required to allow Forth PCI config access
words to work correctly on both 32-bit and 64-bit platforms, along with Zoltan's
original v4 patch. There are 2 main fixes included:

- Implement and convert PCI encode-unit/decode-unit to static methods
  - Fix my-address and my-unit on 64-bit platforms

With this series applied it is possible to execute the Forth PCI config words as
documented in various drivers as below:

PPC (32-bit):

0 > showstack  ok
0 > " /pci/QEMU,VGA" open-dev to my-self  ok
0 > my-space " config-w@" $call-parent u. 1234  ok
0 > my-space  ok
800 < 1 > my-address  ok
800 0 0 < 3 >

SPARC64 (64-bit, including across PCI bridge):

0 > showstack  ok
0 > " /pci/pci@1,1/QEMU,VGA" open-dev to my-self  ok
0 > my-space " config-w@" $call-parent u. 1234  ok
0 > my-space  ok
11000 < 1 > my-address  ok
11000 0 0 < 3 >
