I see. I just found out that some initialization code from these documents
is just some PNP device init code from pnp_device.c,
and some is already documented in superio/smsc/kbc1100/kbc1100.h, so
currently I don't need these documents. I'm going to use
the DSDT dump to implement other features.

Obviously they are copyrighted works, so you can't contribute any
code which you may have copied from them.

[coreboot] Improving KBC1126 support for HP laptops

2017-02-23 Thread Iru Cai 
Hi,

I'm now doing the port for HP Elitebook 2760p (
https://review.coreboot.org/#/c/18241/) and other HP laptops, but I'm now
having trouble with the EC+SuperIO chip KBC1126.

Now I can use superio/smsc/kbc1100 to enable keyboard support. However, I
still cannot access the EC with ectool, which will give me all 0xff when I
run `ectool -d`. Also I cannot use the touchscreen even I write some ACPI
code.

I have searched and downloaded two SMSC confidential document: a KBC1122
preliminary datasheet and a KBC1122 BIOS porting guide. Is there any
problem if I use them to write some code?

Thanks,
Iru
