Configure the vuart in such a way that it does not inhibit the SuperIO's
UART from functioning correctly. This allows the same DTS to be used for
both configurations with SuperIO and VUART (depending on the BIOS
build). The decision on whether to actually enable VUART can then be
made at runtime.
This change also enables the new uart_routing driver for the SuperIO
case.

Add openbmc-flash-layout-64-alt.dtsi to describe the partitions of the
secondary flash for OpenBMC's 64M static layout.
The layout is the same as openbmc-flash-layout-64.dtsi and the labels
are prepended with "alt-" for the partitions.

A while back, Linus complained about the numeric values printed by the
ARM backtracing code. Printing these values does not make sense if one
does not have access to the kernel ELF image (as is normally the case
when helping a third party on a mailing list), but if one does, they
can be very useful to find the code, rather than searching for the
function name, and then doing hex math to work out where the backtrace
entry is referring to.

In the decompressor's head.S we need to start with an instruction that
is some kind of NOP, but also mimics as the PE/COFF header, when the
kernel is linked as an UEFI application. The clever solution here is
"tstne r0, #0x4d000", which in the worst case just clobbers the
condition flags, and bears the magic "MZ" signature in the lowest 16 bits.
However the encoding used (0x13105a4d) is actually not valid, since bits
[15:12] are supposed to be 0 (written as "(0)" in the ARM ARM).
Violating this is UNPREDICTABLE, and *can* trigger an UNDEFINED
exception. Common Cortex cores seem to ignore those bits, but QEMU
chooses to trap, so the code goes fishing because of a missing exception
handler at this point. We are just saved by the fact that commonly (with
-kernel or when running from U-Boot) the "Z" bit is set, so the
instruction is never executed. See [0] for more details.
To make things more robust and avoid UNPREDICTABLE behaviour in the
kernel code, lets replace this with a "two-instruction NOP":
The first instruction is an exclusive OR, the effect of which the second
instruction reverts. This does not leave any trace, neither in a
register nor in the condition flags. Also it's a perfectly valid
encoding. Kudos to Peter Maydell for coming up with this gem.

Add USB overcurrent pin muxing on SoM layer. On DRC02 and PDK2 the USB
overcurrent pin isn't connected, but a USB hub on the board takes care
of the USB overcurrent instead. Therefore disable it there with the
property disable-over-current.

Currently, the imx6q-wandboard Ethernet does not transmit any

This issue has been exposed by commit f5d9aa79df ("ARM: imx6q:
remove clk-out fixup for the Atheros AR8031 and AR8035 PHYs").
Fix it by describing the qca,clk-out-frequency property as suggested

If an USB port is an OTG port, then we should add the usb-role-switch
property. Otherwise XUSB setup fails and therefore padctl is unable to
set up the ports. This leads to broken USB and PCIe ports. Add the
usb-role-switch properties to Tegra124 device-trees to fix the problem.
The error message shown without this patch is e.g:

Note that the phandle indirection is kept for the EMC operating

The Medcom Wide and PAZ00 boards don't specify the power supply for the
backlight, which means that the Linux driver will provide a dummy one.
Wire up an explicit dummy to also make the DT schema validation succeed.
Unfortunately I don't have access to the schematics for the Medcom Wide,
so I don't know if a more accurate description is possible.
The AC100 (PAZ00) schematics from here:
https://www.s-manuals.com/pdf/motherboard/compal/compal_la-6352p_r1.0a_schematics.pdf
aren't entirely clear which one of the supplies powers backlight, but
the panel supply is probably close enough.
