2019-10-20soc/amd/common/lpc: Add SuperIO decode functionMarshall Dawson
The LPC-ISA bridge supports two ranges for SuperIO control registers. Add a generic function to allow a mainboard to enable the appropriate range. Provide #define values that are more descriptive than the register's field names.

2019-10-08device: Use scan_static_bus() over scan_lpc_bus()Nico Huber
Devices behind LPC can expose more buses (e.g. I2C on a super-i/o). So we should scan buses on LPC devices, too.

2019-09-09soc/amd/common/lpc: Add decode disable functionMarshall Dawson
It is already trivial to set D14F3x44 to 0, but add a function to wipe both that and the settings in D14F3x48, along with x48's associated addresses.

2019-06-06soc/amd/stoneyridge: Move LPC support to commonMarshall Dawson
AMD devices traditionally have the LPC-ISA bus at 14.3 and the definition has been very consistent. Relocate the feature from stoneyridge into common/block.
