[meta-xilinx] problem with using ubifs in u-boot on zynq7000

[avallash]

Hi Edward,
First of all, thank you for your reply. The thread in which you solved this
issue was priceless for me.
I can now mount ubifs volumes and read from them as well as boot kernel.
I also experimented with using atomically replaced symlinks for kernel/SW
updates and it seems to work well as well.

this is true for me as well now. I suppose this is related to u-boot update
or other implementation of probe for other flash access type.
It's good to know that the upstream u-boot has this solved already (like I
wrote earlier, right now I'm stuck with petalinux).

In coming days I will summarize my changes and what results I got - I think
it may be a good thing for me to write it as a wiki for first time QSPI
flash and ubifs users in u-boot - if you know a good place top post it
apart from this thread, please let me know.

Best regards,
A.
