source: soft/giet_vm/giet_drivers/mmc_driver.h @ 378

giet_vm optimizations:

  • Several modifications in GIET_VM in order to support compilation with GCC optimizations (-O2) activated.
  • Adding missing volatile in some global variables.
  • Using ioread and iowrite utility functions in peripheral drivers which prevent GCC to remove writes or reads in hardware memory mapped registers.
  • Code refactoring of stdio printf functions. Now, shr_printf and tty_printf function reuse the same function body. The only difference is that shr_printf wraps printf function call with TTY get lock and release lock.
