If boot from sd1, bmode sd1 work well. If boot from qspi1, bmode qspi work well.
This is expected. If boot from qspi, but we use 'bmode sd1', this will not work.
The reason that introduce bmode command is to boot from different media, but
now we use wdog signal to trigger pmic reset, which means the SoC will be
powered off and powered on. There is no reason to keep bmode. This patch
needs my previous wdog patch set.

Peng.
