Don,
Please ask u-boot questions on the u-boot mailing list.

$ grep UART include/configs/da830evm.h
#define CONFIG_SYS_NS16550_COM1 DAVINCI_UART2_BASE /* Base address of UART2 */
#define CONFIG_SYS_NS16550_CLK clk_get(DAVINCI_UART2_CLKID)
#define CONFIG_CONS_INDEX 1 /* use UART0 for console */
Just change DAVINCI_UART2_BASE to DAVINCI_UART1_BASE.
(and make sure your boot loader enables the pinmux for UART1)
