[U-Boot] console_init_r problem with ingenic jz4740 cpu

[xiangfu]

Hi

the u-boot stop at console_init_r function.

here is part of board_init_r function code.

/** leave this here (after malloc(), environment and PCI are working) **/
	/* Initialize devices */
	devices_init ();

	jumptable_init ();
	debug("DEBUG: jumptable over\n"); [1]

	/* Initialize the console (after the relocation and devices init) */
	console_init_r ();
	debug("DEBUG: console_init_r over\n");[2]
/** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** **/

I add two lines for debug.
 
the [1] is output form serial console. but [2] never show up.
I also add some "puts" in the console_init_r function. it's not show in the serial console

give me some advice 

thanks

Best Regards
