ec: add support for KBC1126 in HP laptops
- let the coreboot build system insert the two blobs to the coreboot image
- EC and Super I/O initialization
- ACPI support
Tested on 2760p, 8460p, 2570p, 8470p.
Issue:
Kernel gives the following error:
ACPI Error: No handler for Region [ECRM] (...) [EmbeddedControl]
ACPI Error: Region EmbeddedControl (ID=3) has no handler
TODO:
- consider moving the Super I/O initialization code to ramstage, or
reuse the existing sio/smsc/kbc1100 code (if so, how to add the
additional kbc1126 specific functions to sio/kbc1100)
- sort out the ACPI code which is mostly from the ACPI dump of vendor
firmware
- find out why the digitizer in hp/2760p doesn't work
- GRUB payload freezing on all HP Elitebooks may be related to EC
