Binutils ld has an annoying misfeature (apparently a regression from a
few years ago) that alignment directives (and alignment specifiers on
symbols) apply only to the runtime addresses and not, apparently, to
the load address region specified with the "AT>" syntax. The net
result is that by default the LMA output ends up too small for the
addresses generated in RAM. See here for some details:
https://sourceware.org/ml/binutils/2013-06/msg00246.htmlhttps://sourceware.org/ml/binutils/2014-01/msg00350.html
The required workaround/fix is that AFAICT any section which can have
inherit a separate VMA vs. LMA from a previous section must specify an
"ALIGN_WITH_INPUT" attribute. Otherwise the sections will get out of
sync and the XIP data will be wrong at runtime.
No, I don't know why this isn't the default behavior.
A further complexity is that this feature only works as advertised
when the section is declared with the "AT> region" syntax after the
block and not "AT(address)" in the header. If you use the header
syntax (with or without ALIGN_WITH_INPUT), ld appears to DOUBLE-apply
padding and the LMA ends up to big. This is almost certainly a
binutils bug, but it's trivial to work around (and the working syntax
is actually cleaner) so we adjust the usage here.
Note finally that this patch includes an effective reversion of commit
d82e9dd9 ("x86: HACK force alignment for _k_task_list section"), which
was an earlier workaround for what seems to be the same issue.

This test checks if it can write at the edges of RAM within the kernel
image. The problem is that this memory is not meant to be trampled on.
With the help of custom linker scripts, place 32-byte buffers at those
edges.
Only linker scripts for QEMU on x86 and Cortex-M3 are provided, to avoid
having to maintain too many of them, in case the reference linker
scripts in the kernel change.

This allows running the sanitycheck with:
--tag unified_capable -x KERNEL_TYPE=unified
to run the unified kernel with the tests it is currently known to be
able to run.

$srctree for the application might not be set to be $ZEPHYR_BASE, use
$ZEPHYR_BASE instead to be more explicit in the build.

Add more specifications or qualify some to the sanity check test cases
for them to be ran in real hardware:
- kernel types (micro vs nano)
- platforms / arches to exclude / include
- one that is removed (for the PCI sample) as it cannot be ran
without extra information

Many test configs are the same, remove complexity and duplication by
using just one kernel config where applicable.
This removes the usage of ARCH which is a remnant from the days where
we had to specify the architecture of the board, the architecture is now
part of Kconfig and determined basded on the board configuration.
This will also make it easy adding new architectures to test cases without
having to add an architecture specific config file when it is actually not
needed, for example now that we will enable micro-kernel support on ARC.

The old 'config_whitelist' directive in testcase.ini has been removed.
We use the new expr_parser module to parse a 'filter' directive which
is a boolean expression. This gives a great deal more flexibility
in how tests can be filtered.
To keep the tree bisectable, use of config_whitelist in testcase.ini
converted to the new expression language.
