Take a look for mx31ads.c as an example. You need to setup the chip select like in mxc_setup_weimcs() function.
BTW, I don't see any current mx6 board with NOR in mainline U-boot.
I already did the reset with this lines in the board/freescale/mx6q_boardsabreauto.c board_init()
writel(0x00020001,WEIM_BASE_ADDR); writel(0x1C022000,WEIM_BASE_ADDR + 0x8); writel(0x0804a240,WEIM_BASE_ADDR + 0x10);
However, the uboot code hangs when i runt on the board */ 1896 ulong flash_get_size (phys_addr_t base, int banknum) 1897 { 1898 flash_info_t *info = &flash_info[banknum]; 1899 int i, j; 1900 flash_sect_t sect_cnt; 1901 phys_addr_t sector; 1902 unsigned long tmp; 1903 int size_ratio; 1904 uchar num_erase_regions; 1905 int erase_region_size; 1906 int erase_region_count; 1907 struct cfi_qry qry; 1908 unsigned long max_size; 1909 1910 memset(&qry, 0, sizeof(qry)); 1911 1912 info->ext_addr = 0; 1913 info->cfi_version = 0; 1914 #ifdef CONFIG_SYS_FLASH_PROTECTION 1915 info->legacy_unlock = 0; 1916 #endif 1917 1918 info->start[0] = (ulong)map_physmem(base, info->portwidth, MAP_NOCACHE); 1919 printf("Estamos ok con el pointer malo %u \n",info->portwidth); 1920 if (flash_detect_cfi (info, &qry)) <-------------------------------------------------------------------------------------------- It hangs in the reset commands cfi_flash.c
