* ARC: export __udivdi3 for modulesVineet Gupta2016-08-191-0/+2
| | | | | | | | | Some module using div_u64() was failing to link because the libgcc 64-bit divide assist routine was not being exported for modules Reported-by: avinashp@quantenna.com Cc: stable@vger.kernel.org Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
* ARC: Build system: Makefiles, Kconfig, Linker scriptVineet Gupta2013-02-111-0/+56
Arnd in his review pointed out that arch Kconfig organisation has several deficiencies: * Build time entries for things which can be runtime extracted from DT (e.g. SDRAM size, core clk frequency..) * Not multi-platform-image-build friendly (choice .. endchoice constructs) * cpu variants support (750/770) is exclusive. The first 2 have been fixed in subsequent patches. Due to the nature of the 750 and 770, it is not possible to build for both together, w/o special runtime glue code which would hurt performance.
