Allows to run 'avb verify' multiple times which can be useful after a failure to be able to re-flash the partition and try again.
Signed-off-by: Gary Bisson gary.bisson@boundarydevices.com --- Hi,
This was added because of the following scenario: 1- fastboot flash boot boot.img 2- avb verify -> fails because vbmeta wasn't updated 3- fastboot flash vbmeta vbmeta.img 4- avb verify -> fails because it can't allocate memory as previous buffer wasn't freed
Let me know if you have any questions.
