mark 649a90497e No need to check for CPU_ARM7500 being defined as this option implies
CPU_ARM7 which has to be checked anyway.

mark 02d0fd2ea5 Added function fpe_set_execption_mask() to allow the FP exception mask
to be manipulated.
During initialisation the exception mask is set to allow divide by zero
and overflow exceptions to be signaled.

mark 24e50982df Report the core identity string now available from the core header when
booting.
After assembling the post FP processing callback branch call
sync_icache() if CPU_SA110 is defined.
Return a valid signal code when raising a SIGFPE exception so
the cause of the SIGFPE can be determined.
Added the functions arm_fpe_getcontext() and arm_fpe_setcontext()
to obtain the FP context in a FPE independant form for the ptrace()
syscall.

mark 9d18e41fd8 No longer need the relocation function arm_fpe_mod_reloc() as this is now
sorted out at link time.
fpe_arm_header is now the header structure for the fpe and no longer
a pointer to a header structure.

mark bbf3f35a4c Pass the cpu structure to the FPE boot function so that the FPU class
and type can be updated if a FPA is detected.

thorpej 5c67e5fad9 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

mark c1b23518d2 ARM FPE is now secure i.e. user processes cannot use FP instructions
to access kernel memory.

mark 23d71d4d59 Fixed undefined instruction handler chaining. The FPE will now correctly
pass on an undefined instruction if it was not an FP instruction.

mark 94fa0b2f1b post instruction emulation callback now expects a trapframe structure
to be passed as well as the fp frame.
FPE<->kernel glue code now builds a trapframe structure for passing in
and out of the post instruction emulation callback.
Signal delivery during FP emulation now works correctly.
