There are 2 methods currently available in coreboot to load
ramstage from romstage: cbfs and vboot. The vboot path had
to be explicitly enabled and code needed to be added to
each chipset to support both. Additionally, many of the paths
were duplicated between the two. An additional complication
is the presence of having a relocatable ramstage which creates
another path with duplication.
To rectify this situation provide a common API through the
use of a callback to load the ramstage. The rest of the
existing logic to handle all the various cases is put in
a common place.

If the SerialIO devices are put into ACPI mode then it is possible
to use ACPI to instantiate the touchpad in the kernel without
needing to have a platform level driver to do the binding.
This is the "new way" of describing on-board I2C devices and the
upstream kernel is starting to add ACPI IDs to drivers so they can
be used in this fashion. For the Cypress touchpad use a generic
ACPI ID of "CYPA0000" to describe it.
In order to support the proper scoping of the touchpad device under
the appropriate I2C controller device the mainboard.asl file needs
to be included after pch.asl so the I2C device exists.

Remove the bit of code that was putting the SerialIO devices into

add the appropriate ACPI Methods to allow the kernel to control the
power state of the device.
The problem seems to be that if the device is put in D3Hot state
before it is switched from PCI to ACPI mode then it does not properly
export its PCI configuration space and cannot be woken back up.
Adding the ACPI Methods for _PS0/_PS3 allows the kernel to transition
the device into D0 state only when it is necessary to communicate with
the device, then put it back into D3Hot state.

It also used a 32KiB code cache region. The BWG's limitations for
the code and data region before memory is up was wrong. It consists
of a 16-way set associative 1MiB cache. As long as enough addresses
are not read there isn't a risk of evicting the data/stack.
Now create a 64KiB cache-as-ram region split evenly between romstage
and the MRC wrapper. Additionally cache the memory just below
4GiB in CBFS size. This will cover any code and read-only data needed.
