Currently for Armv7 plaforms the quotient calculated in pl011
uart init code is moved to register r1.

This patch moves the quotient to register r2 as done for other
platforms in the udiv instruction. Value of register r2 is then
used to calculate the values for IBRD and FBRD register

Currently the MDCR_EL3 initialisation implicitly disables
MDCR_EL3.SPME by using mov_imm.

This patch makes the SPME bit more visible by explicitly
disabling it and documenting its use in different versions
of the architecture.

Coherent I-cache is causing a prefetch violation where when the core
executes an instruction that has recently been modified, the core might
fetch a stale instruction which violates the ordering of instruction
fetches.

The workaround includes an instruction sequence to implementation
defined registers to trap all EL0 IC IVAU instructions to EL3 and a trap
handler to execute a TLB inner-shareable invalidation to an arbitrary
address followed by a DSB.

Make the spinlock implementation use ARMv8.1-LSE CAS instruction based
on a platform build option. The CAS-based implementation used to be
unconditionally selected for all ARM8.1+ platforms.

The previous CAS spinlock implementation had a bug wherein the spin_unlock()
implementation had an `sev` after `stlr` which is not sufficient. A dsb is
needed to ensure that the stlr completes prior to the sev. Having a dsb is
heavyweight and a better solution would be to use load exclusive semantics
to monitor the lock and wake up from wfe when a store happens to the lock.
The patch implements the same.

Introduce timeout_init_us/timeout_elapsed() delay tracking with CNTPCT.

timeout_init_us(some_timeout_us); returns a reference to detect
timeout for the provided microsecond delay value from current time.

timeout_elapsed(reference) return true/false whether the reference
timeout is elapsed.

Cherry picked from OP-TEE implementation [1].

LTDC modifies the clock frequency to adapt it to the display. Such
frequency change is not detected by the FDCAN driver that instead
caches the value at probe and pretends to use it later.

This change fixes the issue by moving the FDCAN to PLL4_R,
leaving the LTDC alone on PLL4_Q.

a5ds only has always-on power domain and there is no power control
present. However, without the pwr_domain_off handler, the kernel
panics when the user will try to switch off secondary cores. The
a5ds_pwr_domain_off handler will prevent kernel from crashing,
i.e. the kernel will attempt but fail to shut down the secondary CPUs
if the user tries to switch them offline.

This patch adds mapping for secure FLASH0 for qemu/virt and
qemu/qemu_sbsa platforms. This change is targeted for sbsa but since both
platforms share common code, changes in common defines was necessary.

For qemu_sbsa, this patch adds necessary mapping in order to boot without
semi-hosting from secure FLASH0. EFI need to stay in FLASH1 (share it with
variables) since it need to "run in place" in non secure domain. Changes
for this are under RFC at edk2-platforms mailing list:
https://patches.linaro.org/patch/171327/


(edk2-platforms/Platform/Qemu/SbsaQemu/SbsaQemu.dsc).

In docs qemu/virt is described as using semi-hosting, therefore this change
should be orthogonal to existing assumptions while giving possibility to
store both bl1 and fip in FLASH0 at some point (additional changes required
for that).
