Changes in v4:
- change RFC to PATCH
- update cover letter
- rebase on v2017.03
Changes in v3:
- solve issue in compute partition_entry_lba update :
missing / lba_size
- rework and split patches for unrelated change after review
from Cristophe Kerello and Simon Glass
- rebase on v2017.03-rc1
Changes in v2:
- split serie to reduce patches size
(separate disk part and cmd impact and add precursor patch)
- split large function
