 1.11  14-Mar-2021  skrll Remove an unnecessary if statement in gic_v2m_msi_alloc when finding a
'count' that fits the available.
 1.10  11-Dec-2020  jmcneill Preserve ST Lower and Upper fields when clearing Mask bit in the MSI-X
vector control register.
 1.9  07-May-2020  jmcneill branches: 1.9.2;
Do not store a pointer to the passed in struct pci_attach_args
 1.8  02-Dec-2019  msaitoh Use PCI_MSIX_"TBL"BIR_MASK instead of PCI_MSIX_"PBA"BIR_MASK for MSI-X table.
This is not a real bug because both macros have the same value.
 1.7  14-Oct-2019  jmcneill Add support for Amazon's Graviton MSI controller.

Graviton has a GICv3 with a modified GICv2m (!) for MSIs. Instead of
sending messages to a fixed address with the SPI as data, the Graviton's
GICv2m uses a different address for each vector with "don't care" as data.
 1.6  17-Jun-2019  jmcneill branches: 1.6.2;
- Disable MSI/MSI-X when making changes
- MSI: Write the vector count to the Multi Message Enable (MME) field
- MSI: Set DATA to the first LPI number, not the last
 1.5  07-Dec-2018  jakllsch branches: 1.5.4;
