Review of d486779f50 (StarOS decision 44):
- A write to HW_ARMFIQMASK re-samples the attached core's IRQ and FIQ lines,
as writes to HW_ARMIRQFLAG and HW_ARMIRQMASK do.
- Tests: FIQ masking and unmasking of a latched cause (wide and
byte-assembled writes, then an acknowledgement); two pending IRQ sources,
where acknowledging one keeps the line asserted and acknowledging the
last lowers it.
The attached core cannot be used after it is destroyed: Starlet::Shutdown
resets m_core then m_memory with nothing in between, ~Starlet destroys
m_core (declared after m_memory) first, Init attaches only after the last
path that can fail, StarletMemory::Reset keeps the core, which is still
alive, and the probe's core is a local declared after its memory.
