With the addition of support for custom opensbi version in commit
5c7166d387
(boot/opensbi: add support for version configuration), we can no
longer be sure that the Buildroot patches can be applied - So move them to a
0.9 subdir to ensure they are only applied when the _LATEST_VERSION is used.

Subject: [PATCH] Makefile: unconditionally disable SSP
|
|
|
|
Though -nostdlib is passed in {C,+AS,DTSCPP}FLAGS, -fno-stack-protector
|
|
must also be passed to avoid linking errors related to undefined
|
|
references to '__stack_chk_guard' and '__stack_chk_fail' if toolchain
|
|
enforces -fstack-protector.
|
|
|
|
