2020-05-11soc/amd/common/block/lpc: Add config options for eSPIFurquan Shaikh
eSPI on Picasso is configured using the LPC bridge configuration registers. This change enables config options to allow SoC to select if it supports eSPI (SOC_AMD_COMMON_BLOCK_HAS_ESPI) and mainboard to select if it wants to use eSPI instead of LPC for talking to legacy devices and embedded controllers (SOC_AMD_COMMON_BLOCK_USE_ESPI).

2020-05-05soc/amd/common/block/lpc: Add lpc_disable_spi_rom_sharingRaul E Rangel
If a Picasso platform wants to use GPIO 67 it must disable ROM sharing. Otherwise ROM access is incredibly slow.

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.
