system76-coreboot/src/soc/amd/picasso/Kconfig
Marshall Dawson c0b8d0d5b5 soc/amd/picasso: Update UARTs 
Add a function to uart.c to ensure the right IOMux settings are
programmed for the console UART.  Update Kconfig to reflect the
new addresses.

Give the user the ability to downclock the UARTs' refclock to
1.8342MHz.

Add the abiltiy to use an APU UART at a legacy I/O address.

Update the AOAC register configuration for the two additional
UARTs.
