2011-03-17sim: bfin: check for kill/preadMike Frysinger5-2/+25
If the host system (like Windows) doesn't support these functions, then make sure we don't use them. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-03-15sim: bfin: add GPIO device simulationMike Frysinger7-28/+369
This takes care of the MMR interface and pushing up interrupts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-03-15sim: bfin: fix brace styleMike Frysinger27-27/+54
2011-03-15sim: bfin: fix brace styleMike Frysinger58-161/+342
2011-03-15sim: bfin: handle AZ updates with 16bit adds/subsMike Frysinger2-1/+6
We weren't updating AZ when doing a 16bit add or sub insn. Implement it. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-03-15sim: bfin: skip acc/ASTAT updates for movesMike Frysinger2-6/+10
No point in moving unchanged acc values to the acc regs, and avoid updating the acc ASTAT bits when only reading. This fixes incorrect changing of the ASTAT bits when they're only being read. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-03-15sim: bfin: handle AN (negative overflows) in dsp mult insnsMike Frysinger2-8/+40
The current dsp mult handler does not take care of overflows which turn values negative (and thus set AN in ASTAT). So implement it. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-03-15sim: bfin: handle V overflows in dsp mult insnsMike Frysinger2-7/+15
The current dsp mult handler does not take care of overflows and updating the V ASTAT bit. So implement it. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-03-15sim: bfin: decode ASTAT on failureMike Frysinger2-34/+79
When testing ASTAT regs, specific bit differences carry a lot more meaning than when checking the value of a data register. So automatically decode the bits of the two values and print things out so that people don't have to manually do it themselves every time.

2011-03-15sim: bfin: handle saturation with fract multiplicationsMike Frysinger2-0/+6
The saturation behavior with fract modes differs from non-fract modes. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-03-14sim: bfin: forgot to cvs add the changelogMike Frysinger1-0/+29
2011-03-06sim: bfin: new portMike Frysinger101-0/+30214
This can boot Das U-Boot and a Linux kernel. It also supports Linux userspace FLAT and FDPIC (dynamic and static) ELFs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
