Hi Pavel,
I have built the Raspberry Pi 1 and 2 BSPs with the latest 4.11 branch. I plan
on testing them soon.
I also tried to build the 4.11 sparc/sis BSP, but it failed to compile:
../../../../../../../rtems-src/rtems-4.11/c/src/../../cpukit/libdl/rtl-obj.c:585:47:
error: 'CPU_CACHE_LINE_BYTES' undeclared (first use in this function)
old_end = (uintptr_t)sync_ctx->end_va & ~(CPU_CACHE_LINE_BYTES - 1);
It looks like rtl-obj.c uses CPU_CACHE_LINE_BYTES, but a grep only shows that
is defined for ARM.
Do we need to back port these defines for the other CPU architectures as well?
Thanks,
Alan
