looks like it did not, @AdithyaBaglody?

Not that the while series introducing linker orphan warning has been removed and need to be submitted cleanly and after verifying that those bugs are not introduced.

@nashif there were 2 PRs which has the fix for the orphan sections. #10507 (merged) and #10542 (open). when these are combined with the orphan sections changes it works on all ARM platforms.

@dcpleung can u please resubmit the orphan section and just apply my patch(#10542 ) on top of it.

I have tested this on mps2_an385 and sam_e70 and frdm_k64f and it was working fine on Friday.

linker: warn about orphan sections
b9632d3 
(Previous patch set was reverted due to issue with priv_stack.
 Resubmitting after fixing the faults caused by priv_stack.noinit
 not at the end of RAM.)

This adds a linker flag and necessary changes to linker scripts
so that linker will warn about orphan sections.

Relates to zephyrproject-rtos#5534.

Fixes zephyrproject-rtos#10473, zephyrproject-rtos#10474, zephyrproject-rtos#10515.

(Previous patch set was reverted due to issue with priv_stack.
 Resubmitting after fixing the faults caused by priv_stack.noinit
 not at the end of RAM.)

This adds a linker flag and necessary changes to linker scripts
so that linker will warn about orphan sections.

Relates to #5534.

Fixes #10473, #10474, #10515.
