Martin Roth 25c717d664 Documentation: Fix broken links

This change mostly changes  links that were identified as broken by
the 'website_scans' jenkins job.

There were some links that seem to be up at times, but that are
identified by link-checker as broken because of SSL issues.

At least one other link was changed to point to archive.org so
that it doesn't break at some point in the future.  We should
probably try to make sure that everything is archived there and
point to those versions when possible.

There are still lots more links to do.

ASUS P8H61-M LX

This page describes how to run coreboot on the ASUS P8H61-M LX.

Flashing coreboot

+---------------------+------------+
| Type                | Value      |
+=====================+============+
| Socketed flash      | yes        |
+---------------------+------------+
| Model               | W25Q32BV   |
+---------------------+------------+
| Size                | 4 MiB      |
+---------------------+------------+
| Package             | DIP-8      |
+---------------------+------------+
| Write protection    | no         |
+---------------------+------------+
| Dual BIOS feature   | no         |
+---------------------+------------+
| Internal flashing   | yes        |
+---------------------+------------+

Internal programming

The main SPI flash can be accessed using flashrom. By default, only the BIOS region of the flash is writable. If you wish to change any other region (Management Engine or flash descriptor), then an external programmer is required.

The following command may be used to flash coreboot:

$ sudo flashrom --noverify-all --ifd -i bios -p internal -w coreboot.rom

The use of --noverify-all is required since the Management Engine region is not readable even by the host.

Known issues

S3 suspend/resume does not work. This is the case for both coreboot and the vendor firmware, tested with Linux 4.9, Linux 4.17, and OpenBSD 6.3. Interestingly, it is possible to resume from S3 with Linux, but only if the resume is started immediately after the suspend.
There is no automatic, OS-independent fan control. This is because the Super I/O hardware monitor can only obtain valid CPU temperature readings from the PECI agent, whose complete initialisation is not publicly documented. The coretemp driver can still be used for accurate CPU temperature readings.

Untested

PCIe graphics
parallel port
PS/2 keyboard
EHCI debug
S/PDIF audio

Working

USB
Gigabit Ethernet
integrated graphics
PCIe
SATA
PS/2 mouse
serial port
hardware monitor (see Known issues for caveats)
onboard audio
front panel audio
native raminit (2 x 2GB, DDR3-1333)
native graphics init (libgfxinit)
flashrom under the vendor firmware
flashrom under coreboot
Wake-on-LAN
Using me_cleaner (add -S --whitelist EFFS,FCRS if not using me_cleaner as part of the coreboot build process).
