[U-Boot] Booting mx28 from battery

Hi,

Has anyone tested booting U-boot on mx28 powered by a battery only?

From a quick glance at arch/arm/cpu/arm926ejs/mxs/spl_power_init.c ,

it does appear to support it.

I haven't tested it myself yet, but would like to hear if anyone has been successful with such configuration.

Thanks,

Fabio Estevam
