mark 06d8713b3d arm32 kernel source restructure. 
- IOMD specific interrupt handling. These files are mainly the old
    arch/arm32/irq* files moved here and updated for new iomd device etc.
    (revision history maintained).

mark 187f8c7c3d Remove local definitions of macros to push and pull trapframes and instead 
include machine/frame.h to get these definitions.

mark e626201c12 Adopt as standard, the instruction sequence for storing the trapframe that 
includes the workaround from the SA110 STM^ bug. This allows one piece of
code to be used to store the trapframe on all CPU types.

mark bc3f67bb21 Use the irqblock array to provide the information about which interrupts 
should be blocked for each irq currently asserted.
 1997-01-06 02:35:46 +00:00
mark 9c855e4d1b Provide alternative trapframe push and pull macros from the StrongARM. 
These alternative macros have a workaround for the STM^ bug in revision < 3
StrongARM CPU's that causes incorrect register saving if a cache line fill
is in progress during the STM.

mark 81f6df323e *Major* rewrite, long overdue. 
The irq delivery code has been rewritten. On entry to the irq vector the
processor is switched to SVC32 mode so all interrupt routines now run
in SVC32 mode rather than IRQ32 mode. This fixes lots of irq re-enabling
problems.
Interrupt latency times are now vastly improved for high priority interrupts.
Cleaned up calling ast() before returning to USR32 mode (don't need to
mess about with trapframe copying.
Cleaned up all the comments and sorted out their indentation.
Rewritten the soft interrupt delivery code.
Added generic ARM7500 support rather than just RC7500 support.

mark 459cefbe67 Added support for the RC7500 interrupt registers 
Added interrupt chaining.
Removed some dead debugging code.
Guarded several sanity checks with #ifdef DIAGNOSTIC
Make sure interrupts are disable while updating the IOMD interrupt
masks.

mark 181c7ad5cd Added a new function fiq_getregs() to transfer the FIQ mode register 
into a fiqhandler structure.
Updated fiq_setregs to use symbols in assym.h for offsets into
fiqhandler structures.

mark 47804c6e17 Table of interrupts names has been padded out to 14 characters so that 
it can be filled in when interrupt handlers are attached. Table moved
from the text area to the data area.

mark e03778a035 Updated irq names, replaced reserved irq 1 with irq softclock. 1996-03-08 20:44:13 +00:00
mycroft fc9d84fb46 assym.s -> assym.h 
(Some ports did this already.)
