configs/imx8mmpico: bump bsp components to version tn-kirkstone_5.15.71-2.2.0
Those components are aligned with NXP BSP lf-5.15.71-2.2.0. This commit introduces arm-trusted-firmware upstream patches to compile the needed version with newer gcc and binutils.

Subject: [PATCH] fix(build): allow lower address access with gcc-12
|
||||
|
||||
With gcc-12 any lower address access can trigger a warning/error
|
||||
this would be useful in other parts of system but in TF-A
|
||||
there are various reasons to access to the lower address ranges,
|
||||
example using mmio_read_*/writes_*
|
||||
|
||||
So setup to allow access to lower addresses while using gcc-12

Subject: [PATCH] feat(build): add support for new binutils versions
|
||||
|
||||
Users of GNU ld (BPF) from binutils 2.39+ will observe multiple instaces
|
||||
of a new warning when linking the bl*.elf in the form:
|
||||
|
||||
ld.bfd: warning: stm32mp1_helper.o: missing .note.GNU-stack section implies executable stack
|
||||
ld.bfd: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
|
||||
ld.bfd: warning: bl2.elf has a LOAD segment with RWX permissions
|
||||
ld.bfd: warning: bl32.elf has a LOAD segment with RWX permissions
|
||||
|
||||
These new warnings are enbaled by default to secure elf binaries:

|
||||
|
||||
Fix it in a similar way to what the Linux kernel does, see:
|
||||
https://lore.kernel.org/all/20220810222442.2296651-1-ndesaulniers@google.com/
|
||||
|
||||
Following the reasoning there, we set "-z noexecstack" for all linkers
|
||||
(although LLVM's LLD defaults to it) and optional add
|
||||
--no-warn-rwx-segments since this a ld.bfd related.
