* linux: arc: disable kernel unwinding to fix modules loadingAlexey Brodkin2016-06-221-3/+1
| | | | | | | | | | | | | | | | | | | | | With update of binutils for ARC (this is now based on upstream 2.26) we noticed issues with loadable kernel modules. Something like that was happening: --------------------->8------------------- mbcache: unknown relocation: 49 insmod: can't insert './mbcache.ko': invalid module format --------------------->8------------------- More details could be found in that discussion in binutils mailing list: http://thread.gmane.org/gmane.comp.gnu.binutils/74662 As of now the simplest work-around is to disable in-kernel unwinder for now. That will at least allow us to use modules again. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Vineet Gupta <vgupta@synopsys.com> Cc: John Crispin <john@phrozen.org>
* linux: add support of Synopsys ARCHS38-based boardsJohn Crispin2016-02-181-0/+183
This patch introduces support of new boards with ARC HS38 cores. ARC HS38 is a new generation of ARC cores which utilize ARCv2 ISA. As with ARC770 we're addind support for 2 boards for now: [1] Synopsys SDP board (AXS103) This is the same base-board as in AXS101 but with FPGA-based CPU-tile where ARCHs38 core is implemented. [2] nSIM Again this is the same simulation engine but configured for new instruction set and features of new CPU.
