Reboot kernel，bootrom does not update boot config status.

Imx6q linux 3.0.35

Switch boot config to sd3, as kernel is loaded from sd3 and then change boot config to sd4, reboot system, the system load from sd3 again.

Why does not bootrom update boot cofig status?

If provide POR_B pin reset sequence, the same result as uper description.

Hello,

Please check the boot configuration, using SRC_SBMR1 register.

Also, please verify U-boot environment, where kernel, rootfs are really located.

Only POR provides BOOT_MODE and BOOT_CFG re-read.

Have a great day,
Yuri
