Jumping (currently rebooting, see crosbug.com/p/8100) to the RW image should
be done by vboot_init(), not vboot_pre_init().
As currently written, vboot_init() has to come AFTER these function calls:
task_init(); // sets up interrupts so that uart will work
watchdog_init(1100); // in case we fall over somewhere
uart_init(); // we'd REALLY like to see some debugging output
system_init(); // may go away with crosbug.com/p/8100
keyboard_scan_init(); // check for F3 to go to recovery mode
flash_init(); // maybe set RO regions (this should come earlier!)
eeprom_init(); // this is where the try_b flags are kept
