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 >
