7c9498f7cb Move setsoftast() and friends into cpu.h and make them into macros, so arm26 
is the same as every other port (except arm32).

4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This 
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.

769e82477f Move contents of <machine/spl.h> to <machine/intr.h>. 
Add IST_* macros to <machine/intr.h>, mostly for the feature-list tickbox.
Generally tidy up.

6e3e3a755d Don't include <machine/spl.h> any more. 
Include <machine/intr.h> everywhere than uses spl(9) functions.

a776e1268d General cleanup of definitions of translation table stuff. 
Also add PPN[8] for the A540.  Now all I need are two more RAM cards for my
A540 so I can test it.

a86d1f4891 Add a lock around the scheduler, and use it as necessary, including 
in the non-MULTIPROCESSOR case (LOCKDEBUG requires it).  Scheduler
lock is held upon entry to mi_switch() and cpu_switch(), and
cpu_switch() releases the lock before returning.

Largely from Bill Sommerfeld, with some minor bug fixes and
machine-dependent code hacking from me.

ba6517aa9c Adjust register spacing to take A0 into account. This should make supporting 
8-bit uses of the 8005 (such as, I suspect, 8-bit Ether3 cards) easier.

d7eebd9227 Basic driver for CHIPS 82C710 Universal Peripheral Controller and friends, 
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).

85dda25e94 move "options PULLDOWN_TEST" into sys/sys/mbuf.h (in #ifdef _KERNEL), 
as it is no wthe default setting for everyone.

the reason we still use the name "PULLDOWN_TEST" while it is now default:
kame code sharing.

f096772215 Two changes for endianness-independence (when we finally split of the SEEQ 8005 
driver and make it MI):

Set the ByteSwap bit on big-endian hosts, so we can use 16-bit transfers to get
at packets whatever.

Treat Tx/Rx headers as arrays of four bytes rather than as 32-bit words.

7d83a5201a bus_space version of if_ea.c -- should have been committed before. 
Transmit and receive buffer sizes aren't an intrinsic property of the card,
so they belong in if_ea.c rather than if_eareg.h.

Correct some comments in if_ea.c

9c47f8b134 Read the ECID from each podule just before we launch the kernel. This means 
that the ROM page registers on the podules are likely to end up pointing at
the page with the ECID in it, so NetBSD can recognise the podules.

This is necessary for my i-cubed EtherLan cards, at least.

b5d3226a07 General tidying up, notably: 
- Get the Ethernet address from the card's description string, rather than
   relying on RISC OS to set it.
 - Don't mention this is a SEEQ8005 -- that's all an "ea" can be.
 - Use format_bytes to display the amount of buffer RAM.
