Function imx_system_off() writes SNVS_LPCR register to power off the SoC
without bit masking. This clears other bits like LPWUI_EN and breaks
the function of SoC wake-up using RTC alarm. Fix it by updating poweroff
related bits only.

Fixed the qemu 32 bit clang build fail caused because of
no march32 directives in TF_CFLAGS_aarch32 variable
march32_directive is initialized later in Makefile and since clang build
uses Immediate set instead of Lazy set , TF_CFLAGS_aarch32 doesn't

of the BL31_BASE address starting with TF-A v2.5. Since then the

The ARMv8 ARM says about the values in the ID register scheme:
==== D17.1.3 Principles of the ID scheme for fields in ID registers ===
The ID fields, which are either signed or unsigned, use increasing
numerical values to indicate increases in functionality. Therefore,
if a value of 0x1 indicates the presence of some instructions, then
the value 0x2 will indicate the presence of those instructions plus
some additional instructions or functionality. This means software
can be written in the form:
if (value >= number) {
// do something that relies on the value of the feature
}
=======================================================================
So to check for the presence of a certain architecture feature, we
should not check against a certain specific value, as it's done right
now in several cases.
Relax the test for Fine Grained Trapping (FGT) to just check against
the field being 0 or not.
This fixes TF-A crashing due to an unhandled exception, when running a
Linux kernel on an FVP enabling ARMv8.9 features. The value of
ID_AA64MMFR0_EL1.FGT went from 0b0001 to 0b0010 there.

Right now, the delegated attestation module is not used in TF-A. This
means it's not even getting built and so the CI system cannot detect
build regressions.
Eventually, delegated attestation will be involved in a new runtime
service exposed by BL31 to lower exception levels. We are not there
yet but let's already include it into BL31 image, so we get build
coverage and static analysis on the code. Note that we make sure to
cover both PLAT_RSS_NOT_SUPPORTED=0 and PLAT_RSS_NOT_SUPPORTED=1
configurations.
Delegated attestation is currently made dependent on measured boot
support. This dependency is not at the source code level (attestation
code does not invoke any measured boot interfaces) but it is rather a
logical dependency: attestation without boot measurements is not very
useful...
For now, this is good enough for our purpose but the conditions under
which the attestation code is included might change in the future.
