The base address of UART peripheral should be given in R0, not in R1.
Otherwise the console_stm32_core_flush issues an assert message.
This issue was highlighted with recent changes in console flush functions.

The issue is that, when interrupt is triggered and RAS handler
is entered, after interrupt handler finishes, TF-A will re-enter
bl32 and then crash.
sdei_dispatch_event() may return failing result in some cases,
for example kernel may not have registered a handler or RAS event
may happen early during boot. We restore the NS context when
sdei_dispatch_event() returns failing result.

This allows PSCI in TF-A to signal platform power states to QEMU
via a controller in secure space.

This required a sbsa-ref specific version of PSCI functions for the
platform. Also adjusted the MMU range to also include the new EC.

Add a new MMU region for the embedded controller and increase the
size of xlat tables by one for the new region.

sbsa-ref in QEMU creates clusers of 8 cores, it may create up to 512
cores in upto 64 clusters. Implement a qemu_sbsa specific topology file
and increase the BL31_SIZE to accommodate the bigger table sizes. Change

Rather than re-create this file in multiple qemu variants instead
caclulate the shift needed to convert MPIDR to position.

The Linux Automation MC-1 is a SBC built around the Octavo Systems
OSD32MP15x SiP. The SiP features up to 1 GB DDR3 RAM, EEPROM and
PMIC. The board has eMMC and a SD slot for storage.

The SDRAM calibration values are taken as is from the DKx boards, which
seem to be suitable for operation at German room temperature.

This is deemed ok for now, but for use in the field, the SiP will likely
need to have its timings determined in a climate chamber.

This patch does not change code, it only updates comments and macro name
for 6th bit of Status Register. So TF-A binary stay same.

6th bit of the Status Register is named TX EMPTY and is set to 1 when both
Transmitter Holding Register (THR) or Transmitter Shift Register (TSR) are
empty. It is when all characters were already transmitted.

There is also TX FIFO EMPTY bit in the Status Register which is set to 1
only when THR is empty.

In both console_a3700_core_init() and console_a3700_core_flush() functions
we should wait until both THR and TSR are empty therefore we should check
6th bit of the Status Register.

So current code is correct, just had misleading macro names and comments.
This change fixes this "documentation" issue, fixes macro name for 6th bit
of the Status Register and also updates comments.

Cortex N1 erratum 1946160 is a Cat B erratum present in r0p0, r1p0,
r2p0, r3p0, r3p1, r4p0, and r4p1.  The workaround is to insert a DMB ST
before acquire atomic instructions without release semantics.  This
issue is present starting from r0p0 but this workaround applies to
revisions r3p0, r3p1, r4p0, and r4p1, for previous revisions there is no
workaround.
