baytrail: add support for routing gpio pins to smi/sci
In order for gpio pins to trigger an smi/sci the GPIO_ROUT
register needs to be set accordingly. For SMI, the ALT_GPIO_SMI
register needs to be enabled for each gpio as well.
The first 8 gpios from the suspend and core well are the only gpios
that can trigger an SMI or SCI. The settings for the GPIO_ROUT
and ALT_GPIO_SMI register are not commited until the SMM settings
are enabled in the southcluster.
BUG=chrome-os-partner:23505
BRANCH=None
TEST=Built and booted. Manually triggered SCI by changing GPE0a_EN
and toggling PCH_WAKE_L on the EC console.
