Can you please be more specific?
There is a bigger story behind which should be also described.
The issue which this patch is addressing is that when image recovery application
is running U-Boot SPL or FSBL with upstream u-boot is not able to work with the
flash unless board is power off/on again.
It suggest that baremetal application is using flash in certain mode and U-Boot
is another. That's why I want to know that this change actually does.
If that means that it uses the same mode as baremetal application or so.
