On STM32MP15, there is currently an OP-TEE shared memory area at the end
of the DDR. But this area will in term be removed. To allow a smooth
transition, a new flag is added (STM32MP15_OPTEE_RSV_SHM). It reflects
the OP-TEE flag: CFG_CORE_RESERVED_SHM. The flag is enabled by default
(no behavior change). It will be set to 0 when OP-TEE is aligned, and
then later be removed.

"soc_uart0" is neither of them, and consequently the Linux kernel
complains that it cannot find the root console device when just given
"earlycon" on the kernel command line:
===========

when built-in calibration is executed.

About a year ago there was a change in the underlying Arm platform design
framework, which lead to a reorganisation of the interrupt map (to make
room for multi-chip designs).
This lead to the PL011 debug UART interrupt to move from SPI 115 to SPI
415. Unfortunately there is not a good or easy way to auto-detect this
change: Flooding the TX FIFO and checking GICD_ISPENDR registers might
be possible, but sounds a bit over the top for BL31.
So we would need to break one group of images: newer ones, as we do right
now, or older ones.
By now every interesting FPGA image seems to use the newer IRQ, so in
the interest of having a smooth experience for most users, lets switch
to this IRQ.
When people are interested in older images, they can either change the
number back in the .dts file, or provide a patched DTB on the FPGA
command line.

The Arm FPGAs run in mostly one clock domain, which is used for the CPU
cores, the generic timer, and also the UART baudrate base clock. This
single clock can have different rates, to compensate for different IP
complexity. So far most images used 10 MHz, but different rates start to
appear.
To avoid patching both the arch timer frequency and UART baud base fixed
clock in the DTB manually, we would like to set the clock rate
automatically. Fortunately the SCP firmware has the actual clock rate
hard coded, and already programs the PL011 UART baud divider register
with the correct value to achieve a 38400 bps baudrate.
So read the two PL011 baudrate divider values and re-calculate the
original base clock from there, to use as the arch timer frequency. If
the arch timer DT node contains a clock-frequency property, we use that
instead, to support overriding and disabling this autodetection.

Some FPGAs come with a GIC that has an ITS block configured. Since the
ITS sits between the distributor and redistributors, we can autodetect
that, and already adjust the GICR base address.
To also make this ITS usable, add an ITS node to our base DTB, and
remove that should we not find an ITS during the scan for the
redistributor. This allows to use the same TF-A binary for FPGA images
with or without an ITS.
