Change subject: asus/am1i-a: set UART_FOR_CONSOLE to 1 instead of default 0 ......................................................................
Patch Set 1: Code-Review+1
For some reason the code sets up SP2 instead of SP1, so super slow serial as a result of very high default divider is expected.
Another option is to have the romstage set up SP1 (or both)?
src/mainboard/asus/am1i-a/romstage.c -#define SERIAL_DEV PNP_DEV(0x2e, IT8623E_SP2) +#define SERIAL_DEV PNP_DEV(0x2e, IT8623E_SP1)
