annotate packages/hal/synth/arch/current/include/hal_io.h @ 1862:d27de7fdbf21

* include/hal_io.h: Add cyg_hal_sys_shmget(), cyg_hal_sys_shmat() and cyg_hal_sys_shmdt() system calls * src/synth_syscalls.c: Implementations of cyg_hal_sys_shmget(), cyg_hal_sys_shmat() and cyg_hal_sys_shmdt(). Moved cyg_hal_sys_mmap() from the flash driver to here.
