PCI MSI: Remove unused/obsolete macros and definitions
Impact: cleanup, spec compliance
This patch does:
- Remove unused msi/msix_enable/disable macros.
User should use msi/msix_set_enable() functions instead.
- Remove unused msix_mask/unmask/pending macros.
These macros are useless because they are not based on any of
the PCI Local Bus Specifications properly.
It seems that they were written based on a draft of PCI spec,
and that the draft was the MSI-X ECN that underwent membership
review in September 2002.
(* In the draft, the size of a entry in MSI-X table was 64bit,
containing 32bit message data and DWORD aligned lower address
plus a pending bit and a mask bit.(30+1+1bit) The higher
address was placed in MSI-X capability structure and shared
by all entries.)
- Remove PCI_MSIX_FLAGS_BITMASK.
This definition also come from the draft ECN.
