Hi Steven,
thank you for your answer.

But this original code seems to be ok.
static int rs_brg_map[] = {
6, /* BRG7 for SMC1 */
7, /* BRG8 for SMC2 */
0, /* BRG1 for SCC1 */
1, /* BRG2 for SCC2 */
2, /* BRG3 for SCC3 */
};
/* Wire BRG7 to SMC1 and BRG8 to SMC2 */
immap->im_cpmux.cmx_smr = 0x11;
Best regards
Marco
