about mtd erase fix series

[Marek Behún]

Hi Tom, Jagan,

in July I resent the series
  Fix `mtd erase` when used with mtdpart
https://patchwork.ozlabs.org/project/uboot/list/?series=253565&state=*

There was a build error in CI, more info at 
  https://lists.denx.de/pipermail/u-boot/2021-July/455851.html

The CI link mentioned
  https://source.denx.de/u-boot/custodians/u-boot-spi/-/pipelines/8345
gives 404 now.

Jagan, could you please retrigger CI for this, and send me results?
The series still applied cleanly on master branch and compiled for my
config.

The fix is needed for `mtd erase`.

Marek
