[Qemu-devel] [PATCH] Add support for 82371FB (Step A1) and Improved support for 82371SB (function 1)

[Carlo Marcelo Arenas Belon]

Greetings,

as part of the debugging for the previous problem on FreeBSD and based on the 
documentation from Intel from :

  http://www.intel.com/design/intarch/datashts/290550.htm

the following patch does some cleanup in the current sources so that a reset
for function 1 (the IDE interface) for PIIX and PIIX3 is supported and PIIX
could be used instead of PIIX3 if needed (by swapping the corresponding
piix?_init and pci_piix?_ide_init functions in hw/pc.c or creating another
cloned emulated "pc").

most of the code is currently not linked, except for the addition of
piix3_reset to the reset for function 1 of PIIX3 to match the spec and the
removal of 2 duplicated lines on the reset functions for PIIX3 and PIIX4, but
it is left behind as it could be useful for a new target for testing of legacy 
OSs or embedded.

Carlo
