[edk2] [PATCH edk2-platforms 10/12] Hisilicon/D0x: Switch to generic PciHostBridge driver
Posted by Heyi Guo 7 years, 10 months ago 
Address translation support is added to generic PciHostBridge driver
in edk2 by commit 74d0a33, so we can switch to it for Hisilicon D03
and D05 which are using address translation between device address and
host address for resource BAR.

As noted in reply to the previous patches, I think we should avoid 1:1
mapping the I/O space like this.

20 bits of I/O space should be plenty, i.e., up to 16 segments using
64 KB of I/O space each.
