Message:

Initial work on sparc32 architecture support.

  • /boot/arch/sparc32 loosely based on arm32 port
  • /kernel/arch/sparc32 based on abs32le template
  • /uspace/lib/c/arch/sparc32 based on sparc64 implementation with incompatible parts temporarily commented out.

Work currently done:

  • AMBA plug and play support in loader
  • initial MMU setup
  • kernel booting
  • register window traps
  • context_save_arch/context_restore_arch

Completed milestones: M1, M2
