移植到WLIT项目的redboot源代码

2001-04-04  Mark Salter  <[e-mail]>

	* src/main.c (do_version): Print version string if defined.

2001-03-14  Mark Salter  <[e-mail]>

	* src/net/net_io.c: Make sure console setup gets reverted when TCP
	connection closes.

	* src/main.c (cyg_start): Restore console comm channel after return
	from GDB stub.

2000-12-21  Mark Salter  <[e-mail]>

	* src/flash.c (fis_init): Use CYGBLD_REDBOOT_FLASH_BOOT_OFFSET to
	decide where to create default images.

	* cdl/redboot.cdl (CYGBLD_REDBOOT_FLASH_BOOT_OFFSET): Use this
	to define offset from start of FLASH to start of boot image.

2000-12-07  Jesper Skov  <[e-mail]>

	* src/load.c (load_srec_image): Refuse to load data to a location
	not in RAM.

	* src/xyzModem.h: 
	* src/xyzModem.c (xyzModem_stream_close): New function - tidy up
	and print some statistics about the download.  Better handling
	of CAN (cancel) function.

	* src/load.c (load_srec_image): Consume all data, not just to
	final record.  This makes Ymodem happier.  Also, call xyzModem_close().

	another connection if in stub (gdb detach behavior).
