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 Change-Id: I6b16eb7e26303eda740f52d667dedb7cc04b4ef0 Signed-off-by: Iru Cai <mytbk920423@gmail.com> Reviewed-on: https://review.coreboot.org/19072 Reviewed-by: Arthur Heymans <arthur@aheymans.xyz> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
