This patch fixes an issue when secure world timing information
can be leaked because Secure Cycle Counter is not disabled.
For ARMv8.5 the counter gets disabled by setting MDCR_El3.SCCD
bit on CPU cold/warm boot.
For the earlier architectures PMCR_EL0 register is saved/restored
on secure world entry/exit from/to Non-secure state, and cycle
counting gets disabled by setting PMCR_EL0.DP bit.
'include\aarch64\arch.h' header file was tided up and new
ARMv8.5-PMU related definitions were added.

This patch adds support for Corstone-700 foundation IP, which integrates
both Cortex-M0+ and Cortex-A(Host) processors in one handy, flexible
subsystem.
This is an example implementation of Corstone-700 IP host firmware.

Cortex-M0+ will take care of boot stages 1 and 2(BL1/BL2) as well as
bringing Host out RESET. Host will start execution directly from BL32 and
then will jump to Linux.

It is an initial port and additional features are expected to be added
later.

Currently, console drivers prepend '\r' to '\n' by themselves. This is
common enough to be supported in the framework.

Add a new flag, CONSOLE_FLAG_TRANSLATE_CRLF. A driver can set this
flag to ask the framework to transform LF into CRLF instead of doing
it by itself.

SMMUv3 driver functions which are called from BL1 and BL31
currently use counter-based poll method for testing status
bits. Adding Delay Timer driver to BL1 and BL31 is required
for timeout-based implementation using timer delay functions
for SMMU and other drivers.
This patch adds new function `fvp_timer_init()` which
initialises either System level generic or SP804 timer based on
FVP_USE_SP804_TIMER build flag.
In BL2U `bl2u_early_platform_setup()` function the call to
`arm_bl2u_early_platform_setup()` (which calls
`generic_delay_timer_init()` ignoring FVP_USE_SP804_TIMER flag),
is replaced with `arm_console_boot_init()` and `fvp_timer_init()`.

This patch fixes FVP_Base_AEMv8A model hang issue with
ARMv8.4+ with cache modelling enabled configuration.
Incorrect L1 cache flush operation to PoU, using CLIDR_EL1
LoUIS field, which is required by the architecture to be
zero for ARMv8.4-A with ARMv8.4-S2FWB feature is replaced
with L1 to L2 and L2 to L3 (if L3 is present) cache flushes.
FVP_Base_AEMv8A model can be configured with L3 enabled by
setting `cluster0.l3cache-size` and `cluster1.l3cache-size`
to non-zero values, and presence of L3 is checked in
`aem_generic_core_pwr_dwn` function by reading
CLIDR_EL1.Ctype3 field value.

The rk3399 suspend code saves and restores the debug uart settings, but
right now always does this for the default uart. Right now this works
only by chance for the majority of rk3399 boards, which do not deviate
from that default.

But both Coreboot as well as U-Boot-based platforms can actually use
different uarts for their output, which can be configured from either
devicetree or Coreboot-variables.

To fix this, just use the stored uart-base information instead of the
default constant.

Rockchip platforms can be booted from either u-boot or coreboot.

So far the Coreboot-console was initizalized from a coreboot data struct
in the early_param2 callbacks and dt-based consoles with data from the
rockchip_get_uart_* functions.

But later code may also need this console information for example for
special suspend handling. To make this easy follow a suggestion from
Julius Werner and move the coreboot<->dt distinction into the
rockchip_get_uart_* functions, thus making correct data about the used
uart available to all Rockchip platform code at all times.

This includes a new rockchip_get_uart_clock as well, because while the
dt-platforms right now always just default the rate defined in a constant
Coreboot provides its own field for the clock rate and we don't want to
loose that information for the console init. Similarly the rk_uart_*
variables should move into the non-Coreboot code, to prevent them from
being marked as unused, which also requires the rk_get_uart_* functions
to move below the actual dt-parsing.

Coverity has identified that the __aeabi_imod function will loop forever
if the denominator is not a power of 2, which is probably not the
desired behaviour.

The functions in the rest of the file are compiler implementations of
division if ARMv7 does not implement division which is permitted by the
spec. However, while most of the functions in the file are documented
and referenced in other places online, __aeabi_uimod and __aeabi_imod
are not. For this reason, these functions have been removed from the
code base, which also removes the Coverity error.
