Add l1_set_leds(), which sets the Fuel and Tezro front-panel LEDs, and
l1_set_display(), which writes line 2 of the Tezro's L1 display. Both
can be called from a panic notifier.

The SGI Fuel and Tezro front-panel LEDs are set through the L1 system
controller, whose LED request switches off every LED outside its mask,
so send the pattern of both LEDs on each change. Probe takes over the
PROM's state without writing it.

Register the front-panel LED device on a Fuel and a deskside Tezro and
blink the red LED on panic. A Tezro also shows "Linux booting", "Linux
running" or "Linux panic" on line 2 of its L1 display.

Hello Imre,
This series is rather large.
I would recommend you to submit a minimal patch series
to get the basic support for your new board, such that
it can boot with a ramdisk and serial console.
Then in the next cycle, send separate series for ata,
net, leds, mfc, rtc, etc.
Kind regards,
Niklas

Hi Niklas,
Thanks for having a look. I checked what the minimum is: 31 of the 53
patches (1, 6-24, 26-29, 31-36 and 39) boot a Tezro to a ramdisk with a
serial console. Two mfd/ioc3 patches have to be part of that, as they
provide the console UARTs (31 for IOC4 on the Tezro, 36 for the IOC3 on
the Fuel). The rest separates cleanly into follow-ups: the remaining
Bridge fixes (2-5), ioc3-eth (25, 38), rtc (30), the IO8 serial IRQs (37),
machine identification and the Odyssey widget (40-44), ata (45-47, 49),
the defconfig refresh (48) and the LEDs (50-53).
I’ll wait for Thomas to say whether he prefers it split that way for v3.
Thanks,
Imre
