@Patater @AlessandroA Just needs a rebase and should be ready for final testing |

uVisor CI is expected to fail on this PR right now. This PR changes uVisor APIs, and we need to merge our tests PR first in order to use the new APIs. Unfortunately, merging our test PR will break uVisor CI for everybody else until this mbed OS PR also goes in. Merging these two PRs requires careful coordination. |

OK, please keep us updated |

@Patater Ready for the uvisor tests to be updated. Can you do that now? |
|
@sg- Yes, I'll merge those now. |
uVisor doesn't set the PSP of the target thread. The RTOS sets the PSP of the target thread from the target thread's TCB. However, when interrupts of higher priority than PendSV happen between the call to uVisor to switch boxes, and the RTOS setting PSP, the uVisor vIRQ interrupt handler will attempt to use an invalid PSP (the PSP from before the box and thread switch). This leads to a crash. Make box and thread switching atomic by disabling interrupts immediately before the box switching until immediately after the new PSP is set.

Description
This ships an updated uVisor that supports ARMv8-M, and provides fixes for uVisor on ARMv7-M.
This previously added the following, but this target is not yet ready to be added to mbed OS; so we'll hold off on these things.
Add ARMv8-M Cortex-M33 target (ARM_MPS2_ARMv8MML)Prepare uVisor scripts and components for ARMv8-MStatus
READY
This depends on #4294 being merged first.MergedRelated PRs
