Max Filippov 00273125c3 xtensa: add s32c1i sanity check ... Add a brief sanity test of S32C1I functionality. This instruction is needed by the kernel and userland as part of the base ABI (including GCC atomic builtins, certain threading packages, future atomic support in the C++ standard, etc). However, correct operation of this instruction requires some cooperation by hardware external to the processor (such as bus bridge, bus fabric, or memory controller). Minimally exercising this mechanism and reporting explicit status early in the boot process is helpful to chip vendors using the Linux kernel as a benchmark of correctness of hardware. As it turns out, S32C1I is not exercised by the kernel and by uClibc based userland as of early June 2008. This is expected to change soon as both incorporate more recent open source developments.
