Common code sequences have been factored out, the code has been made
more generic, has better handling of corner cases and is actually much
shorter.
It also adds probing for almost all recent (since 1999) ITE Super I/O
chips to probe_superio. I did verify against all ITE datasheets
(including those not available any more) that the probing was
non-destructive.
For the ITE IT8712F, the complete configuration is dumped and as
comparison the default value from the data sheet is printed.
More information can be extracted easily, however this needs loads of
datasheet surfing.
This code has been tested extensively, dumping for other ITE chips will
follow as a separate patch.

The first byte of the flash chip was read at the start of the function
and later written back to address 0 if the flash chip was not identified
as SST28SF040, which means most of the time. This write caused corruption
of flash contents when verifying a SST49LF160C part.

the system boot to a command line.
This patch comments out the code to set up the vga framebuffer to allow
the system to boot, without this fix the system hangs during elfboot.
The only line that is absolutely necessary to change is the SMRAM setup,
however I've commented out all vga setup to make it very obvious to both
the kernel/payload and anyone looking at the code that vga isn't
currently working. This setup might also be better handled in
northbridge.c, if it doesn't need to be done before ram init, yet
another reason to comment it all. In the future, LinuxBIOS needs to be
told that the graphics memory area, 1mb or 512kb (at the user or
developer's option), is reserved for the onchip vga, but I'm not sure if
it's taken at the top or bottom of the memory, yet. LB may also need to
set a base address for the AGP aperture and/or be told that range is
reserved as well, whether this was originally the job of the system bios
or vga bios is still a mystery. It also corrects the number of entries
in irq_tables.c, without this fix the kernel would probably complain and
hang due to unmapped IRQs.

The problem was that the disable code was ORing bits into the Legacy_IO
MSR causing issues with the LPC SIOs init code that would manifest as a
hang because the IO would not be decoded correctly. ANDing to clear the
bits fixes the issue.

Then apply NOPs for 200 clock cycles (for simplicity we use 200us here).

It moves the complete naming functionality to
src/cpu/amd/model_fxx/processor_name.c.
The current code sets the processor name string twice for Rev. F CPUs.
In src/cpu/amd/model_fxx/model_fxx_init.c the function
amd_set_name_string_f is called first. Several lines later
init_processor_name is called which doesn't recognize newer CPUs and
actually programs incorrect values, thus overwriting the previously set
CPU name. For example, this resulted in identifying an Opteron 2218 as a
Turion processor.
This patch removes the amd_set_name_string_f function from
src/cpu/amd/model_fxx/model_fxx_init.c and adds support for Rev. F CPUs
to src/cpu/amd/model_fxx/processor_name.c as described in the Revision
Guide for AMD NPT Family 0Fh Processors, AMD Document ID 33610 Rev 3.00,
October 2006.
