This ancient board with Intel e7505 invalidates cache while it does HW
scrubbing for ECC in romstage. This breaks usbdebug console and prevents
system from booting.
If both EARLY_CONSOLE and USBDEBUG are selected, skip ECC scrubbing under
these rare conditions to boot system.

Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.
Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

In the file `COPYING` in the coreboot repository and upstream [1]
just one space is used.
The following command was used to convert all files.
$ git grep -l 'MA 02' | xargs sed -i 's/MA 02/MA 02/'

Add early_smbus.c for romstage-y list and remove respective
include on mainboard romstage.c files.
Tested on AOpen board.

No longer include northbridge files directly in the source for
mainboard romstage.c and fix includes.
Also make required adjustments to function declarations.

It takes about 3 seconds to scrub 8GiB DDR266 RAM.
After ECC scrub XIP cache is disabled for system stability. There is
very little to do in romstage after ECC scrub, especially when RAM
debug messages are turned off. So the delay caused by this is hardly
noticeable.
Cache for complete ROM is re-enabled before ramstage is decompressed,
and it has no unstability issues. So the code required to re-enable
cache for ROM currently already exists in cache-as-ram_ht.inc.
A Kconfig option HW_SCRUBBER enables the scrub to be run on hard
reboots and power-ons.

Tested on real hardware, mainboard with dual Xeon P4 HT CPUs
requires cache-as-ram init code with AP SIPI protocol.
Also enable 2nd CPU and PATA and clean-up Kconfig and ACPI.

Fix delay loop comments. Time waited and the comments did not match
in the origin (e7501), so delays currently "just work".
Move reset detection to main raminit and don't use generic
sdram_initialize for now, as there are local debug
functions I need to use. Fix AOpen respectively.
Disable ecc scrub, until I have it fixed for cache-as-ram use.

This is an old (pre-2005) entry-level server mainboard. The code
is adapted from mainboard/intel/xe7501devkit.
Featured chips:
- Dual socket604
- E7505 northbridge
- 82801DB southbridge (with EHCI debug port)
- 82870p2 PCI-X bridge
- LPC47M102S-MC super-io
- 512kB FWH flash (flashrom does the job well)
What works:
- Dual-Xeon P4/HT boot with microcode update
- RAM: registered ECC DDR266 in dual-channel
- PCI-X slot interrupts with ACPI and I/O apic
- On-board PCI-X GbE and SCSI
- ACPI power-off and wakeup with PME#
Notes :
- Current ACPI is more or less a mess
- Interrupts do not route correctly with PIRQ
- MP-table is not implemented
- Issues with reboots remain (cold and warm)
- Many superio devices are disabled by default
- Audio codec is not investigated
