Summary0000251: elf files for Synopsys ARC are not identified correctly
DescriptionThere are 3 variants of Synopsys ARC ISA: ARCompact, ARCv2 and ARCv3 and processors based on them
However current implementation of file is not identifying them ideally:

1. ARCompact based elf is incorrectly identified as legacy ARC Tangent A5 which don't exist.
2. ARCv2 is not even listed
3. ARCv3 is incorrectly identified as ARCv2.3

Additional InformationI'm attaching a patch which addresses the above.
TagsNo tags attached.

Subject: [PATCH] Fix names for Synopsys ARC cores

 - 93 was (mis)used all legacy ISA/core: A4, A5...
   Only ARCompact ISA based cores use this machine-id, so rename to
   reflect as such.

 - 195: ARCv2 ISA is missing

 - 253/255: ISA is not ARCv2.3 but ARCv3
