[U-Boot] i.MX6 based board does not work if watchdog support is enabled

[Otavio Salvador]

Hello,

I am trying to add support for watchdog in one board and it is not
working as expected.

I did add the:

#define CONFIG_HW_WATCHDOG
#define CONFIG_IMX_WATCHDOG

into the board config file.

Into the board .c file, I added:

int board_late_init(void)
{
...
#ifdef CONFIG_HW_WATCHDOG
     hw_watchdog_init();
#endif

return 0;
}

and the hw_watchdog_init is indeed called.

It starts booting and shows:

U-Boot 2013.10-rc3-00046-gc1c2434-dirty (Sep 28 2013 - 21:12:53)

CPU:   Freescale i.MX6Q rev1.2 at 792 MHz
Reset cause: WDOG
Board: yyyy
DRAM:  1 GiB
MMC:   FSL_SDHC: 0, FSL_SDHC: 1
In:    serial
Out:   serial
Err:   serial
Net:�

and it in fact resets.

I am booting the board from USB loader. May it be an issue?
