boot init code depending on i2c eeprom value

[christian.buettner@xxxxxxx]

Hi all,

i need to set the pin-mux of the board
init code depending on an ID coming from 
an i2C EEPROM of the board.
Is it possible to do something like
this:


...

//Using the e.g. the postcore_initcall
phase to init i2C
static
int
ecuv6_postcore_init(void)
{
        //Set
I2C EEPROM (24C32R) PIN MUX
        mxc_iomux_v3_setup_multiple_pads(i2c_eeprom_pads,
ARRAY_SIZE(i2c_eeprom_pads));
        imx53_add_i2c2(NULL);
        return
0;
}
postcore_initcall(ecuv6_postcore_init);

//In the console_initcall
phase, i2C should be probed to read ID
static
int
ecuv6_console_init(void)
{
        imx53_init_lowlevel(0);
        ecuv6_set_system_serial();
           

        //get_bb_pcb_number
reads data from 
        char
bb_ID;
        bb_ID
= get_i2c_ID();

        //Set
Pinmux depending on i2C result
        if(bb_ID
= 0xAB) {
         
      mxc_iomux_v3_setup_multiple_pads(AB_pads,
ARRAY_SIZE(AB_pads));
        }
        else
if(bb_ID
= 0xCD) {
         
      mxc_iomux_v3_setup_multiple_pads(CD_pads,
ARRAY_SIZE(CD_pads));
        }
        
        imx53_add_uart0();

        return
0;
}
console_initcall(ecuv6_console_init);

...


Actually this is not working. The i2c_imx:i2c_imx_probe(..)
function gets called later.
Is there a way or concept to do something
like this?
