Also in case of HS38 atomic extensions (LLOCK/SCOND instructions) are built-in by default, so enabling atomic extensions in Buildroot as well. This commit adds support of the core in buildroot.

ARC: Add support for ARC HS38 with Quad MAC & FPU We used to build everything for pretty much baseline ARC HS capable of runnig Linux kernel, which was ARC HS38/48 with MMU and caches. But there's a fully featured ARC HS with additional support for - Dual & quad integer multiply and MAC operations - Double-precision floating-point unit It corresponds to the following ARC HS templates in ARChitect: hs38_slc_full. In fact existing HSDK board uses exactly this configuration in its SoC and this is recommended configuration for Linux use-cases. To make life simpler we have corresponding "-mcpu" and "--with-cpu" options in ARC GCC port so we're going to use it and get binaries built accordingly optimized.

ARC: Add support for ARC HS48 v3.1 processor This patch introduces a recently released significant update to ARC HS family: ARC HS48. One of the major ARC HS48 features is dual-issue pipeline which requires a little bit modified instruction scheduling compared to single-issue cores (HS38), thus new "-mcpu/--with-cpu=hs4x".

# Choice of atomic instructions presence
toolchain: Add config option for atomic intrinsics GCC has several builtin functions that implement atomic operations. Those functions are architecture specific and may not be implemented by the specific toolchain. In case of GCC for ARC those functions rely on LLOCK/SCOND instructions which are optional in ARC CPU's. If ARC CPU doesn't support those instructions but software tries to use them, then application will be aborted with Illegal instruction exception. To avoid confusion user should first specify that their CPU supports atomic extension, which will allow selection of packages that use builtin atomic functions.
