Add the missing instructions to the bottom of armins.dat, run
mkarmins in the same directory.
It now recognises the mnemonic 'cpsie' but not the following 'i'.
The 'msr' instruction should also allow the interrupts to be enabled/
disabled as
msr primask,r0
but msr gives an unknown identifier error for 'primask' and all the
other 'special' register names ('apsr' etc.) Perhaps they have been
given different names, but I cannot find them listed anywhere in the
FPC source.
(and then submit patch) :-)
well, once I have some code which works on the chip, I will ask
someone where to put it :-)

I wrote a procedure to turn on interrupts:-
procedure intenable;nostackframe;
begin
asm
cpsie i
end;
end;
The compilation fails with 'Error: Unrecognized opcode cpsie'
The compiler also does not recognise 'cpsid' and also 'primask' as
in 'mrs r0,primask'
any ideas/workarounds?
