Is somebody already working on adding G4
support? If not, I could provide a rudimentary
- CPU version recognition etc.
- cache initialization.
- save/restore AltiVec context.
Are there suggestions regarding the
implementation of the vector context
save/restore, i.e. should this go to
the core code or should it be a user
Something else that bothers me are the definitions
#define _IO_BASE PREP_ISA_IO_BASE
#define _ISA_MEM_BASE PREP_ISA_MEM_BASE
#define PCI_DRAM_OFFSET PREP_PCI_DRAM_OFFSET
found in lib/libcpu/powerpc/shared/include/io.h
This should be the business of the BSP rather than
the CPU library's!
