Alexey, All,
On 2014-10-30 16:57 +0300, Alexey Brodkin spake thusly:
> Synopsys has recently announced its new ARC HS38 core that is capable of
> running Linux -
> http://www.synopsys.com/dw/ipdir.php?ds=arc-hs38-processor
>
> ARC HS38 is based on ARCv2 ISA and requires special settings of gcc and
> libc.
>
> Also in case of HS38 atomic extensions (LLOCK/SCOND instructions) are
> built-in by default, so enabling atomic extensions in Buildroot as well.
Ditto as for the first patch: are atomics configurable? Ditto the
proposal if not.
> This commit adds support of the core in buildroot.
