Sort the .noinit* input sections by name first, then by alignment if two
sections have the same name. This allows the placement of begin/end symbols to
initialize some areas with a special value.
Update #4678.
Always start the executive in Exception Level 1, Non-Secure mode.
If we boot in EL3 Secure with GICv3 then we have to initialize
the distributor and redistributor to set up G1NS interrupts
early in the boot sequence before stepping down from EL3S to EL1NS.
Now there is no need to distinguish between secure and non-secure
world execution after the primary core boots, so get rid of the
AARCH64_IS_NONSECURE configuration option.
Debug events should be masked at least until after the first context
switch and should usually be masked until a debugger is attached for
application debugging.
Run with stack alignment faults enabled under RTEMS_DEBUG to catch any
stack misalignments early. This makes it easier to track them down
should they ever occur.
Remove usage of SUBALIGN() in aarch64 linkcmds which works around a
difference in behavior on AArch64 platforms. This is no longer necessary
since alignment is now enforced explicitly.
Closes#4178.
The SUBALIGN(4) required on rtemsroset and rtemsrwset for ILP32 builds
was previously present on LP64 builds and causes no issues within RTEMS,
but causes relocation/alignment issues when building libbsd. This
restricts those alignment changes to ILP32 builds.
