The first patch abstracts the geometry retrieved from the identify command and allows both specs to coexist under the same geometry description. From there on, we build the missing 2.0 support in lightnvm core: address format, address conversion and report chnk get log page. The last three patches implement the actual support for 2.0 in pblk. Note that we only port functionality for 2.0. Newer functionality enabled by 2.0 (e.g., wear-leveling) will be submitted in following patches. This patches apply on top of Matias' latest patches.
