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

[Eugeniy Paltsev]

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
