M2351 is still in staging CI, wait for 5.10 release to test this PR.
@gaborkertesz - Can you verify locally if this fix works (https://github.com/ARMmbed/mbed-os/pull/8025/files#diff-9cf75aea879b6b9cc5026af0b8f708a3L429) for Musca as well?

[gaborkertesz]

ARMC6 is working for Musca-A1 (after updating to this change in platform files). Please update GCC as well!

Merge conflict - needs rebasing

[deepikabhavnani]

Rebased and updated for GCC as well.

[gaborkertesz]

GCC update has been tested and works as expected for Musca-A1.

[deepikabhavnani]

@ARMmbed/mbed-os-maintainers - Consider this as high priority for Musca.
@studavekar - Can we test this PR in staging as well for Nuvoton?
