You have already included the mxc_gpio. You must use the mxc_gpio_*
function to access gpios.

Access to register with address + offset is not allowed. The right
structures are already defined in imx-regs.h. Use "struct weim" to
access to the weim registers.

Even here you must use structures to access registers.

CONFIG_SYS_BOOTMAPSZ is condidered obsolete and removed in a recent commit.

Best regards,
