Hello Stefan,

U-Boot now supports the "skip_check" flag to optionally skip the CRC
check at open time. Currently its only possible to set this bit upon
UBI volume creation. But it might be very useful to also set this bit
on already installed systems (e.g. field upgrade) to make also use of
the boot-time decrease on those systems.
This patch now adds a new "ubi" command "ubi skipcheck" to set or clear
this bit in the UBI volume header:
=> ubi skipcheck rootfs0 on
Setting skip_check on volume rootfs0
BTW: This saves approx. 10 seconds Linux bootup time on a MT7688 based
target with 128MiB of SPI NAND.

Just applied it locally and started a travis build [1] for your patch
series.
Unfortunately it breaks [2] sheevaplug board (size limit).
Added Prafulla to cc may he can give a hint, if we can remove something?
@Prafulla: This board drops a lot of build warnings [3] ... is it used
anymore? Do you plan to update to DM support? Or should we
remove this board?
bye,
Heiko
