2007-06-12  Andrew Lunn  <[e-mail]>

	* src/synth_entry.c (__stack_chk_fail): another new function
	needed when building with gcc 4.1.2
	* current/src/synth.ld: place eh_frame_hdr into eh_frame.

2006-07-10  Bart Veer  <[e-mail]>

	* src/synth_entry.c (__stack_chk_fail_local): new function needed
	when building with gcc 4.1.1

2005-11-19  Bart Veer  <[e-mail]>

	* src/synth_entry.c (_linux_entry): brk() is no longer needed to
	get heap memory.

	* src/synth.ld: add new section to contain the heap memory rather
	than rely on brk().
	

2005-11-05  Andrew Lunn <[e-mail]>

	* include/hal_io.h (struct cyg_hal_sys_old_stat): Make the
	structure match the kernel version otherwise the stack gets
	corrupt and we die 'orribly. Added cyg_hal_sys_new_stat for when
	using the new?stat() calls.
	* src/synth_syscall.c (cyg_hal_sys_ftok): use the correct structure 
        member names and use the newstat system call so we get 
	values back which are compatible with glibc ftok() function.
	* tests/ftok.c (new): Test case for the cyg_hal_sys_ftok() 
        function added in the previous patch.

2005-10-19  Alexander Neundorf <[e-mail]>

	HAL_DELAY_US().

2005-03-11  Bart Veer  <[e-mail]>

	customize the sigaction structures.

	* include/hal_io.h: add more signal-related definitions

	only need to specify RTC_PERIOD

	    Andrew Lunn        <[e-mail]>

	* 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.

	Add cyg_hal_sys_readdir(), cyg_hal_sys_lstat(), 
        cyg_hal_sys_fstat() system call toegther with their 
        accompanying data structures and file mode bits

2004-06-18  William Donahue  <[e-mail]>

	* include/hal_io.h (CYG_HAL_SYS_FD_ZERO): Added misisng }

2004-05-27  Alexander Neundorf <[e-mail]>

	* include/hal_io.h: 
	Fix the open/fcntl flags by prepending a leading 0 so that they

        CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
        "default_value" from "calculated". This makes it easier
        to change these values globally.

	otherwise we loop forever.
