Linux on ARM/arm64 will infer from the presence of a /chosen/stdout-path
DT property or of a SPCR ACPI table that the primary console is the serial
port, even if a graphical console is available as well.
So let's introduce a driver that allows the user to set a preference
between graphical and serial if both are available. If the preference
is set to 'Graphical', and any GOP protocol instances have been installed
by the time the ReadyToBoot event is signalled, remove the DT property
and/or the SPCR table entirely.

which only has resolutions for ARM/AARCH64. Move them to an

- The Isp1761UsbDxe driver is not 64-bit compatible. It should be

As described in the LAN9118 datasheet, delays are necessary after some
reads and writes in order to ensure subsequent reads do not see stale

This patch adds helpers to provide these delays automatically, by
performing dummy reads of the BYTE_TEST register (as recommended in the
LAN9118 datasheet). This approach allows the device register file itself
to provide the required delay, avoiding issues with early write
acknowledgement, or re-ordering of MMIO accesses aganist other
instructions (e.g. the delay loop).

Commit a4626006bb ("EmbeddedPkg/Lan9118Dxe: use MemoryFence")
replaced some stalls with memory fences, on the presumption that these
were erroneously being used to order memory accesses. However, this was
not the case.
LAN9118 devices require a timing delay between state-changing
reads/writes and subsequent reads, as updates to the register file are
asynchronous and the effects of state-changes are not immediately
visible to subsequent reads.
This delay cannot be ensured through the use of memory barriers, which
only enforce observable ordering, and not timing. Thus, converting these
stalls to memory fences was erroneous, and may result in stale values
being read.
This reverts commit a4626006bb.

Add a PCD for the link negotiation timeout so the platform can over-ride

The code previously did 2000 iterations of the loop with a 2us stall, so
the code has been changed subtly to set the number of iterations equal

Since the stall time has not changed, the default PCD value is set at
4000 so the original behaviour is not changed.

When reviewing my LAN9118 driver PCD patch [1], Ard Biesheuvel noted
that most calls to gBS->Stall() in this driver seem to be used to
prevent timing issues between the device updating data and the host
reading the values. And that replacing most of these calls with a
MemoryFence() would be more robust.
The only exceptions are the stalls that are enclosed inside retry loops:
- in the AutoNegotiate() function.
This stall is waiting for the link to negotiate, which may require
stalling until it is ready.
- in the Lan9118Initialize() function.
These two stalls are waiting for devices and time out after a number
of retries.
- in the SoftReset() function.
This stall is inside a loop where the comment states:
"If time taken exceeds 100us, then there was an error condition"
In these instances, I kept the stall, but also added a MemoryFence().
