Several more high-end HP EliteBook machines use MXM graphics modules,
e.g. HP EliteBook 8560w.
MXM works! TODO: merge
----------------------
Riku got it working. See:
* SeaBIOS patch 1: <https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/ZHVOSUEYILGFNBKWOFNSDQ7PGCADSMU4/>
* SeaBIOS patch 2: <https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/LK2ZHY6BSKRBUCZ5LMND5IBW3HGLZTMV/>
* mxmdump util: <https://codeberg.org/Riku_V/mxmdump/>
* int tool: <https://codeberg.org/Riku_V/int>
the "int" tool can be used to determine what mxm spec you have, and the mxmdump
util can be used to dump the mxm config. on systems where there is no i2c rom,
the system firmware (in this case libreboot) must provide it via int15h
interrupt. riku's seabios patches implement this.
TODO: Merge in libreboot, with elitebook 8560w support. (riku will probably
merge this himself, but i'm adding it here just in case)
