[ECOS] MIPS 5KC Target

["Devaughn, Hans" <hans.devaughn@siemens.com>]

I have tried building the library, from config tool, for the Atlas and Malta
5KC processors. Both result in the same cache header file error

make[1]: *** [src/hal_misc.o.d] Error 1

The problem is that the generic version of cache header file (on
cyg/hal/var_cache.h) has a check for the MIPS 4KC and generates a compile
error (#error). The 5KC cache header file is in the makefile and on
hal/mips/mips64/current/include/var_cache.h. It would seem that the 5KC
header should be used instead of the 4KC header.

Does anybody have a fix for this apparent problem?

Thanks in advance.

Hans
