[PATCH 1/3] dts: socfpga: Change Mercury+ AA1 devicetree to header

Paweł Anikiel pan at semihalf.com
Mon May 30 06:08:37 PDT 2022


The Mercury+ AA1 is not a standalone board, rather it's a module
with an Arria 10 SoC and some peripherals on it. Remove everything that
is not strictly related to the module.
