Do this via U-Boot

Open davinci.c from the boards directory in U-BOOT.

The stuff regarding pinmux is in there. More specifically:

#define PINMUX0     0x01C40000

/* Enable UART0 MUX lines */
*(volatile unsigned int *)PINMUX4 |= 1;

/* Enable EMAC and AEMIF pins */
*(volatile unsigned int*) PINMUX0 = 0x80000C1F;
