Google Wilco Embedded Controller interface.
Note, the Wilco EC firmware is a modified version of Dell's
typical Latitude EC firmware, that implements a custom mailbox
protocol similar to the one used in the Chromium EC.
This particular EC firmware is not open source, just the
host-side interfaces (kernel and firmware drivers) are.

help
This option provides the 16-bit IO base address for the ACPI
data interface. This is the standard ACPI EC interface that
is used by the ACPI EC drivers in the OS.

help
This option provides the 16-bit IO base address for the ACPI
EC command interface. This is the standard ACPI EC interface
that is used by the ACPI EC drivers in the OS.

help
This option provides the 16-bit IO base address for the host
data interface. This is the interface that is used to drive
the mailbox protocol.

the mailbox protocol.
config EC_BASE_PACKET
hex
default 0x950
help
This option provides the 16-bit IO base address for the EC
mailbox interface data region. This data buffer is used along
with the host command and data registers to drive the EC
mailbox interface. This is also the MEC EMI base address.
