In PlatformBdsPolicyBehavior() we should follow the same pattern as in

- connect all drivers and devices,
- enumerate all boot options,
- enter the Intel BDS FrontPage if the user presses a key different from
Enter.
We set the countdown to 3 seconds, similarly to the timeout that we

After reviewing OvmfPkg's use of its own QemuFwCfgLib instances, it is
clear that its only pre-DXE fw_cfg dependency concerns S3 support (the
QemuFwCfgS3Enabled() call in "PlatformPei/Platform.c").
For ARM guests, S3 is in the distant future, but we can see several
shorter term applications for fw_cfg that all reside in DXE:
- controlling boot order (to be implemented in PlatformBdsLib for Intel
BDS),
- supporting -kernel / -initrd / -append boot on QEMU (to be implemented
in PlatformBdsLib for Intel BDS, similarly),
- loading and linking ACPI tables,
- installing SMBIOS tables.
Therefore it makes sense to add a simple MMIO-based fw_cfg client library
to ArmVirtualizationPkg that for the moment is only available to
DXE_DRIVER modules.
Because MMIO accesses are costly on KVM/ARM, InternalQemuFwCfgReadBytes()
accesses the fw_cfg data register in full words. This speeds up transfers
almost linearly.

Qemu's firmware configuration interface for ARM consists of two MMIO
registers, a 16-bit selector, and a 64-bit data register that allows the
guest to transfer data with 8, 16, 32, and 64-bit wide accesses. Parse the
base address from the DTB, and expose the registers to the rest of DXE via
dynamic PCDs.

Rework the setting of information about a file, in particular
file resizing, file renaming and the returned error codes in case
of error. This rework has implied a rework of the read, write, close
and flush functions.
To strickly separate what has been actually written to the media (flushed)
from what has not been written when a file is open, an "Info" field has
been added to the description of a file.
The field is used to store the modifications done to the file by the
means of SetInfo() like the change of the name or of the size. Such
changes are written to the media only when a flush occurs.
When a file is open, the information pointed to by the "Info" field is
always up-to-date. This is not the case of the information stored in
the "HwDescription" of the file description which from now is just a
mirror of what is written on the media.

This adds support for executing UEFI in a QEMU/mach-virt emulated environment.
The following assumptions are made about the target:
- DRAM base at 0x4000_0000, containing the device tree blob
- DRAM size at least 1 MB
- device tree uses 64-bit physical base addresses and sizes
- ARM architected timer
- Cortex-A15 CPU (if built for 32-bit)
The following information is retrieved from the device tree:
- PL011 UART base address
- GIC base addresses
- virtual timer interrupt
- PL031 RTC base address
- DRAM size, must be at least 128 MB
- virtio MMIO transports
- PSCI 0.2 availability (for reset and poweroff)
The device tree image is relocated and installed as a configuration table
so an EFI stub enabled kernel can be booted directly without the need for
a bootloader.

This is an implementation of ArmPlatformLib that discovers the size of system
DRAM from a device tree blob located at the address passed in
gArmTokenSpaceGuid.PcdDeviceTreeBaseAddress, which should equal the value in

As the device tree blob is passed in system DRAM, this library can only be used
if sufficient DRAM is available (>= 128 MB) and if not using shadowed NOR. The
reason for this is that it makes it easier to guarantee that such a device tree
blob at base of DRAM will not be clobbered before we get a chance to preserve it.
