Running barebox on qemu-system-mips* with '-d unimp' overloads stderr by very very many mips_cpu_handle_mmu_fault() messages: mips_cpu_handle_mmu_fault address=b80003fd ret 0 physical 00000000180003fd prot 3 mips_cpu_handle_mmu_fault address=a0800884 ret 0 physical 0000000000800884 prot 3 mips_cpu_handle_mmu_fault pc a080cd80 ad b80003fd rw 0 mmu_idx 0 So it's very difficult to find LOG_UNIMP message. The mips_cpu_handle_mmu_fault() messages appears on enabling ANY logging! It's not very handy. Adding separate log category for *_cpu_handle_mmu_fault() logging fixes the problem.
