Many parts of the code were duplicating symbols that are defined in
include/common/bl_common.h. It is better to only use the definitions in
this header.

As all the symbols refer to virtual addresses, they have to be
uintptr_t, not unsigned long. This has also been fixed in bl_common.h.

This reverts commit 2f370465

 ("Add support for the SMC Calling
Convention 2.0").

SMCCC v2.0 is no longer required for SPM, and won't be needed in the
future. Removing it makes the SMC handling code less complicated.

The SPM implementation based on SPCI and SPRT was using it, but it has
been adapted to SMCCC v1.0.

ARMv8.4-TTST (Small Translation tables) relaxes the lower limit on the
size of translation tables by increasing the maximum permitted value
of the T1SZ and T0SZ fields in TCR_EL1, TCR_EL2, TCR_EL3, VTCR_EL2 and
VSTCR_EL2.

This feature is supported in AArch64 state only.

This patch adds support for this feature to both versions of the
translation tables library. It also removes the static build time
checks for virtual address space size checks to runtime assertions.

This content has been imported and adapted from the TF GitHub wiki
article 'ARM-Trusted-Firmware-Coding-Guidelines'.

The aim is to increase the visibility of the coding guidelines by
including them as part of the documentation that is within the TF
repository.

Additionally, the documentation can then be linked to by other
documents in the docs/ directory without worrying about broken links
to, for example, the external wiki.

Commit 03364865

 ("Make TF UUID RFC 4122 compliant") changed the scanf
parsing string to handle endianness correctly.
However that changed the number of items sscanf handles, without
adjusting the sanity check just below.

Increase the expected return value from 11 to 16 to let fiptool handle
UUIDs given as blob parameters correctly again.

Method cpld_reset_cpu of bl31 is called from the Linux kernel and uses
GPIO6, GPIO2 pins as SPI bus lines to control the CPLD device. But in the
kernel GPIO6_8 pin are initialized to work in interrupt mode instead of
the input/output mode. This leads to the fact that the SPI bus becomes
non-functional. In this patch we switch the GPIO6_8 pin back to the
input-output mode.

Current implementation of i.MX8QX power management related
features does NOT optimize power number, all system resources
like CCI, DDR, and A cluster etc. are kept in STBY mode (powered
ON) when system suspend or CPU hotplug.

To lower the power number, OFF mode should be adopted for those
system resources whenever they can be OFF, A cluster will be OFF
if the CPUs in the cluster are all off line, DDR/MU/DB can be OFF
if system suspend, IRQ steer can be OFF if the wakeup source is
belonged to system controller partition, so wakeup source runtime
check is used to determine if IRQ steer can be OFF before system
suspend.

If resources are powered off for suspend, they should be restored
properly after system resume.

the new GIC driver interfaces was done incorrectly in rk3328 and rk3368:

 ("rockchip: Migrate to new interfaces").

In the GICv2 driver it is mandated that all interrupts are Group 0
interrupts. This patch simply moves all Group 1 interrupts to Group 0.
