Subject: armv8: LS2080A: Consolidate LS2080A and LS2085A
X-Git-Tag: v2016.05-rc1~31^2
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=3c1d218a1d3048fb576677c47eab43049d0b7778;p=oweals%2Fu-boot.git

armv8: LS2080A: Consolidate LS2080A and LS2085A

LS2080A is the primary SoC, and LS2085A is a personality with AIOP
and DPAA DDR. The RDB and QDS boards support both personality. By
detecting the SVR at runtime, a single image per board can support
both SoCs. It gives users flexibility to swtich SoC without the need
to reprogram the board.
