Currently there's only a single global option to specify the baud rate when communicating with the boot ROM.
The eflash binary has a high-precision PLL clock so it's possible to achieve a higher baud rate, it'd make sense to be able to control this, especially since arbitrary baud rates are very portable.
When using the DT-BL10 board which has a C340N serial I've only had success when using 1M baud (when reading from serial - anything faster and it'd time out.)
