The next version of the linker will complain about rwx segments with permissions and executable stacks:
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=ba951afb99912da01a... https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=0d38576a34ec64a1b4...
These warnings are relevant for ELF binaries loaded by an operating system linker, but do not make sense in the context of u-boot where the objects are loaded by other means.
Disable the warnings using the following options:
--no-warn-rwx-segments
warning: u-boot has a LOAD segment with RWX permissions warning: u-boot-spl has a LOAD segment with RWX permissions
--no-warn-execstack
warning: arch/arm/lib/setjmp.o: missing .note.GNU-stack section implies executable stack NOTE: This behaviour is deprecated and will be removed in a future version of the linker
Signed-off-by: Joel Stanley joel@jms.id.au --- This behaviour can be seen when building with binutils 2.38.90.20220713-2 from Debian testing.
