Subject: [RFC PATCH 0/2] Add support for SBI version to 0.2 

This patch series aims to add support for SBI specification version
v0.2. It doesn't break compatibility with any v0.1 implementation.
Internally, all the v0.1 calls are just renamed to legacy to be in
sync with specification [1].

The patches for v0.2 support in OpenSBI are available at
http://lists.infradead.org/pipermail/opensbi/2019-August/000422.html

Atish Patra (2):
RISC-V: Mark existing SBI as legacy SBI.
RISC-V: Add basic support for SBI v0.2
