* 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.
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
defparam recently.
- minor whitespace & formatting cleanups
to zero page, and it branches to either the rx or tx handler. My intention
is that the tx handler should switch to the rx one the moment it finishes,
without needing a downgrade, which I hope will get rid of the start-of-frame
rx overruns I'm seeing.
While I'm here, move the constants describing the shape of the FIQ state
structures out of if_ecavar.h and into genassym.cf where they belong.
in arm/arm. This version is based on the arm26 version, and includes dumping
the contents of stack frames, with automatic determination of the save code
pointer offset.
arm32/arm32/in_cksum_arm32.c -> arm/arm/in_cksum_arm.c
Also move specification of other checksum stuff to files.arm, even though we
use the MI code for that.
By default, they aren't used, since most cards seem to put the non-OS-dependent
stuff in the main chunk directory. i-cubed cards are a notable exception.
packets. Interrupt enabling is left to the RISC OS driver, medium selection
is untested and it's hard-wired to the MAC address of my card. Not really
for production use.
and a front-end driver for the Ether3. Only semantic change is to remove
ea_claimirq() and ea_releaseirq() on the grounds that the seem too spurious
to warrant a callback to the front-end.
as used on later arm26 system (A5000, A4, A3010, A3020, A4000).
What we have got:
...
upc0 at iobus0 base 0x010000: config state bb 87 1c 00 00
fdc at upc0 offset 0x3f4 not configured
wdc0 at upc0 offset 0x1f0
lpt0 at upc0 offset 0x278
com0 at upc0 offset 0x3f8: ns8250 or ns16450, no fifo
...
What we haven't got:
- FDC support (found, but not configured).
- Clearing lpt interrupts on arm26 systems (needs help from IOEB).
- A upc(4) manual page.
- More than minimal testing (my A3020s don't have root devices).
- A proper probe routine (arm26 can't use one anyway).
