[PATCH v2 0/4] ARC: [plat-hsdk-4xd] initial port for HSDK-4xD board

From: Eugeniy Paltsev
Date: Thu Jun 04 2020 - 13:39:53 EST


Changes v1->v2:
* Fallback to ISA default mcpu flag if custom one isn't supported by
compiler.
* Drop HSDK custom Kconfig options (choose between HSDK and HSDK-4xD) as
we don't need it (at least for now). Instead we select ARC_LPB_DISABLE
for both boards but it's totally OK as HSDK doesn't have LPB so
disabling will be skipped by BCR check in runtime.
* Add missing HSDK-4xD device tree bindings. Convert HSDK device tree
bindings to json-schema.

Eugeniy Paltsev (4):
ARC: allow to override default mcpu compiler flag
ARC: ARCv2: support loop buffer (LPB) disabling
ARC: [plat-hsdk-4xd] initial port for HSDK-4xD board
ARC: [plat-hsdk*] document HSDK-4xD board/SoC bindings
