[U-Boot] Power Savings on ARM/OMAP4

Greetings, I've been playing with controlling a bq2415x battery charger chip on I2C on a custom OMAP4 board. In USB/OTG charging mode the code currently monitors the charger chip in a loop to which I added a msleep(2000) call. I did that thinking that since battery parameters don't change very

I was just bitten in this area today but in a different way. Larger than DDR? Any update larger than the default 4MB dfu_buf[] fails too. (As a hack I redefined dfu_buf[] to be a cast of I think CONFIG_SYS_SDRAM_BASE.) But I'd love to hear more about being able to handle updates larger than DDR
