2011-04-02MIPS: Optimize the setup of CPU optimization flagsDaniel Schwierzeck
The current MIPS CPU config.mk code always expects a MIPS 4kc core. This is not appropiate for other CPUs and SoCs. Replace the current MIPSFLAGS code by cc-option macro and use -march=mips32r2 as default optimization level for all MIPS32 CPUs. Note: Since commit f62fb99941c625605aa16a0097b396a5c16d2c88 all toolchains with binutils prior to v2.16 are not working anymore. As agreed with Shinya Kuribayashi the support for those toolchains will be dropped officially with this patch.

2011-04-02MIPS: Move content of arch/mips/cpu to arch/mips/cpu/mips32Daniel Schwierzeck
All current CPUs and SoCs are based on MIPS32 arch. The complete code resides in the global arch/mips/cpu directory. This is not suitable if other MIPS architectures like MIPS64 or Octeon should be supported in the future. To achieve this the current CPU code is moved to its own mips32 subdirectory. All MIPS32 boards have to use mips32 as config switch in board.cfg.
