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)
