commit a5f89dda5bbaf043ccef47a85983834e25bd3357 Author: Edward O'Callaghan eocallaghan@alterapraxis.com Date: Mon Jun 16 14:13:06 2014 +1000
src/superio/ite/it8772f: Separate mainboard from SIO at obj level
Remove #include early_serial.c and rename to early_init.c as no actual UART configuration is done here. Note that this SIO component still hard codes its base address to 0x2e.
