2013-03-02metag: Headers for core arch constantsJames Hogan1-0/+81
Add a couple of header files containing core architecture constants. The first (<asm/metag_isa.h>) contains some constants relating to the instruction set, such as values to give to the CACHEW and CACHER instructions. The second (<asm/metag_regs.h>) contains constants for the core register units directly accessible to various instructions, and for the registers, fields, and bits in those units. The main units described are the control unit (CT.*), the trigger unit (TR.*), and the run-time trace unit (TT.*). Signed-off-by: James Hogan <james.hogan@imgtec.com>
