Remove the call to abort(). We don't pull in a prototype for it,
...
and there's no sane way to do so.

Merge ast() and userret() between arm32 and arm26. The implementation used
...
is the arm32 one.

Use the correct version of va_arg() for _STANDALONE.

Remove some outdated comments: arm26 kernels use APCS-32 now, which
...
means they don't do silly things like restoring IRQ/FIQ disable bits
on function return.

* Share a common vector page between arm26 and arm32.
...
* Use a common set of exception handlers for all arm32 platforms.
* New FIQ framework based on discussions with Ben Harris, shared
between arm26 and arm32.

Ensure that vidc.h gets installed somewhere -- Xarm32vidc needs it to compile.

mod() was unused. g/c it. New code should use abs() anyway.

Simplify the pixel-clock-rate-setting code, so it always works out the
...
parameters from first principles rather than using a static table for some
rates. This makes it work correctly on ARM7500, for which the table was
bogus (ARM7500 has a different refclk from VIDC20).

Add clockctl device.
...
Note that someone needs to tidy this up, we've got 92 block devices, which just ain't true. Also appears we're actually missing some, eg the ld block device.

Add support for dumping ELF-cormat core files.

Roll the rest of the ports over to the new MI kernel build machinery.
...
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.

Improve comment on the clockswitching asm code, it doesn't use r0 at all, it just needs it to make valid asm.

Fix the asm macros
...
The tmpx registers are now outputs, this makes them all unique.
Add the fact that cc is changed by the asm (not believed to be used but rather be correct)
Correctly specify w as an input and output register, I think this was hiding the bug below!
Allow sum to be in a different input and output register.
Correct bug in psuedo header handling for in4_cksum. Seems that the new macros turned up a latent bug in the psuedo header handling, the code was moving a pointer forward 16 bytes twice, not found before as the ADD16 macro wasn't 100% accurate, as it didn't output w, even though it modified it.

On the i80200, disable ECC in the Bus Controller Unit early on; we
...
don't really have code to deal with ECC errors yet.
2001-12-01 06:33:40 +00:00

Add register definitions for the i80200 Interrupt Controller Unit,

Bus Controller Unit, and Performance Monitoring Unit.

Clarify a comment to state that it is intentional that we attach
...
only the Secondary PCI bus (it's the only bus which can have a
device space hidden from any PCI host on the Primary bus).
Also, use the bus number from the PPB businfo register seecondary bus
field rather than hard-coding "1".

interrupt code. Garbage-collect some unused stuff.

Add a "cacheline_size" argument to pci_configure_bus(). It is used

to set the cacheline size in the BHLC register. This should be the
size of the largest D-cache line on a system.

- convert usage of "defopt" to "defflag" where the relevant option does

not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to

Sprinkle CPWAIT around to enforce some barriers. Also deal with some

pre-B-step errata: must clean-dcache-line to an address before

get cleanred in the dcache array for that line.
