Hello Maintainers,
With latest commit I see that saveenv command corrupts QSPI-flash, meaning if I read QSPI-flash at 0x0 offset RCW(reset configuration word) is erased after saveenv command was executed. This is tested on LS1088ARDB, but it should not be limited to LS1088ARDB rather it will valid for all LS Freescale ARM boards.( like LS1088, LS2080/LS2085, LS1012, LS1043, LS1046).
