On x86, log2() is defined as an inline function in arch/io.h. This is
a remnant of ROMCC, and forced us to not include clog2.c in romstage.
As a result, romstage on ARM has no log2().
Use the inline log2 only with ROMCC, but otherwise, use the one in
clog2.c.

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.

Unfortunately the reference tool chain was updated
without ever even testing it on an abuild run. This
broke a number of ports.
This change gets coreboot at least compiling again
for all supported systems.

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.

Drop comments (from e7501 era) which no longer seem to apply with
e7505. Write the semi-constant D0:F0 table as code. Some register
settings seem to be in different order compared with vendor BIOS,
and will be handled by follow-up patches.
Split RCOMP register copy function in two parts.
Drop some uses of inline and local_mdelay().

Makes the code a bit more readable, IMO. There is no clean way
to implement this as the affected registers are undocumented.
Seems ROMCC cannot handle the enum. Also any of my future changes
would not be even abuild tested as there is no longer a board with
ROMCC and this chipset. E7505 chipset is CAR only from now on.

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.

Adapted from northbridge/intel/e7501 with only minor changes.
This commit provides minimal patch from e7501 and I prefer any
cosmetic clean-up to be done after initial merge.
Due the incomplete register specifications, it is safer to have
e7505 as a separate directory in case I improve it to support
wider range of memory configurations. I have no e7501 to test with.
