Remove the handling of the fw_cfg DT node from VirtFdtDxe now that the fw_cfg client library has been moved to the FDT client protocol, and no longer relies on VirtFdtDxe to pass this information via dynamic PCDs. Since the PCDs in question are now no longer used, remove them from the various DEC and DSC files as well.

|
# "Map PCI MMIO as Cached"
|
|
#
|
|
# Due to the way Stage1 and Stage2 mappings are combined on Aarch64, and
|
|
# because KVM -- for the time being -- does not try to interfere with the
|
|
# Stage1 mappings, we must not set EFI_MEMORY_UC for emulated PCI MMIO
|
|
# regions.
|
|
#
|
|
# EFI_MEMORY_UC is mapped to Device-nGnRnE, and that Stage1 attribute would
|
|
# direct guest writes to host DRAM immediately, bypassing the cache
|
|
# regardless of Stage2 attributes. However, QEMU's reads of the same range
|
|
# can easily be served from the (stale) CPU cache.
|
|
#
|
|
# Setting this PCD to TRUE will use EFI_MEMORY_WB for mapping PCI MMIO
|
|
# regions, which ensures that guest writes to such regions go through the CPU
|
|
# cache. Strictly speaking this is wrong, but it is needed as a temporary
|
|
# workaround for emulated PCI devices. Setting the PCD to FALSE results in
|
|
# the theoretically correct EFI_MEMORY_UC mapping, and should be the long
|
|
# term choice, especially with assigned devices.
|
|
#
|
|
# The default is to turn off the kludge; DSC's can selectively enable it.
