[U-Boot] [PATCH v4 27/27] km_arm: use filesize for erase in update command

[Valentin Longchamp]

We used to have an arbitrary value, which can be a problem if we have a
u-boot image that is bigger than this value.

This patch is dependant on the whole km/arm series and will be included
in the v3 of the series if there is one.
