I will try to use gpio pins PB[4,5, 22:26] by removing the MAX3243C chip from the SBC.
How can I locate the file I have to modify to get the software working accordingly to the previous mentioned change.

Thanks.

The C source file is /arch/arm/mach-at91/board-sam9g20ek.c

Lines 59 - 65 enables two USART

 59         /* USART0 on ttyS1. (Rx, Tx, CTS, RTS, DTR, DSR, DCD, RI) */
 60         at91_register_uart(AT91SAM9260_ID_US0, 1, ATMEL_UART_CTS | ATMEL_UART_RTS
 61                            | ATMEL_UART_DTR | ATMEL_UART_DSR | ATMEL_UART_DCD
 62                            | ATMEL_UART_RI);

 64         /* USART1 on ttyS2. (Rx, Tx, RTS, CTS) */
 65         at91_register_uart(AT91SAM9260_ID_US1, 2, ATMEL_UART_CTS | ATMEL_UART_RTS);
