New board: ThinkPad R500 (experimental)r500-experimental
The ich9deblob and ich9gen utilities were modified, so that they
support reading and/or writing descriptor images where the GbE
region is not defined. These utilities were also re-factored
and tidied up a bit.
A quick was noticed during the course of this work, in that
Compenent 1 Density was being set to 8MiB constantly, even
on systems with 4MiB flash chips. Component 2 Density was
set statically to 2MiB. ich9gen now sets both to 4MiB or 8MiB,
depending on whether building the descriptor for a 4MiB or
8MiB ROM image.
There are still some ACPI bugs (see docs/hcl/r500.html), which
will have to be fixed upstream. TODO: get hw reg dumps from
a factory R500, and compare with the X200 or T400 dumps.
