	* src/main.c (do_help): 
	* src/flash.c: 
	* include/redboot.h: Support nested command structures, like "fis",
	better.

2002-05-17  Jesper Skov  <[e-mail]>

	* doc/redboot_rebuilding.sgml: Rewrote update procedure to become
	truly generic. Some minor tweaks.

	* doc/redboot_cmds.sgml: Added id to cksum command.

	* src/shex.c (load_shex_image): Set entry address to be base
	address.
	* src/load.c (do_load): Same.

	* src/flash.c (fis_create): Infer correct exec and entry
	addresses.

	* src/load.c (load_elf_image): Save load_address/end.

	* src/flash.c: Made fis lock/unlock support optional image name
	instead of addresses. Made a few places of the code use fis_lookup
	instead of scanning the table by steam.
	(do_flash_config): Update flash after configuration has been
	initialized.

2002-05-16  Jesper Skov  <[e-mail]>

	* doc/redboot_cmds.sgml: Updated text on cksum to show the new
	output format.

	* src/xyzModem.c (xyzModem_stream_read): Fix build breakage.

	* doc/redboot.sgml: Some minor tweaks.

	* src/alias.c (lookup_alias): Renamed freemem aliases.

2002-05-15  Jesper Skov  <[e-mail]>

	* src/io.c (verify_action): Replaced 'are you sure' with
	'continue'.
	* doc/redboot.sgml: Same.

	* src/xyzModem.c: Let Y-modem load correct length. Don't remove
	assumed padding bytes since they may well be actual data. Don't
	read anything after the EOF package is received.
	Disabled the Y-modem header stuff again; it still needs the
	padding culling code. So in the end, only the EOF-package read
	was at fault.

	* src/main.c: Tweak cksum output.

	* src/flash.c (fis_create): language tweaks.

	* src/main.c: Always call expand_aliases - leave it to that
	function to look for flash aliases when appropriate.

	* src/flash.c: Moved basic alias expansion into separate file.
	* src/alias.c: New file. Always provide FREE_LOW & FREE_HIGH
	aliases, but also call flash_lookup_alias when defined.

	* include/redboot.h: Added declarations for alias functions. Added
	getc_t and terminate_t types.

	* src/load.c: Use getc_t/terminate_t types. Made raw load abort if
	user tries to load a file too big for memory.

	* cdl/redboot.cdl: Compile alias.c.

2002-05-14  Jonathan Larmour  <[e-mail]>

	* src/version.c: Clarify comments.

2002-05-14  Gary Thomas  <[e-mail]>

	* include/redboot.h: 
	* src/net/net_io.c: 
	* src/net/dns.c: Merge generic "ip" command with "dns" for
	more homogenous interface.

2002-05-13  Gary Thomas  <[e-mail]>

	* cdl/redboot.cdl: Disable CYGOPT_REDBOOT_FIS_REDBOOT_BACKUP
	by default, since its use is currently unclear.

	* src/flash.c (load_flash_config): Check for adequate FIS space
	was incorrect [when FIS directory and FCONFIG are combined].
	(fis_lookup): Image name lookup is case insensitive.

2002-05-10  Gary Thomas  <[e-mail]>

	* src/flash.c: Lots of restructuring in support of combined
	FIS and FCONFIG data.

	* cdl/redboot.cdl: 
	Add new option CYGSEM_REDBOOT_FLASH_COMBINED_FIS_AND_CONFIG
	to allow FIS directory and FCONFIG data to share the same
	physical FLASH block.

2002-05-03  Gary Thomas  <[e-mail]>

	* src/flash.c (load_flash_config): Adjust fconfig database
	address - necessary if FLASH blocks are very small.

2002-05-02  Gary Thomas  <[e-mail]>

	* src/load.c: Rework how decompression is done (with changes
	noted below).  Now turning on decompression works by pushing
	the decompress code into the stream I/O.

	* src/flash.c (fis_load): 
	* src/decompress.c (gzip_inflate): 
	* include/redboot.h: Make decompression code more generalized.

2002-05-01  Gary Thomas  <[e-mail]>

	* include/elf.h: New file.

	* cdl/redboot.cdl: 
	* src/load.c (load_elf_image): Support [simple] ELF images.

2002-04-24  Yoshinori Sato  <[e-mail]>

	* src/xyzModem.c (xyzModem_stream_terminate): Increase time for
	cleanup from 100ms to 250ms.

2002-04-23  Jonathan Larmour  <[e-mail]>

	* src/syscall.c (__do_syscall): Rename EIO to NEWLIB_EIO to
	pre-empt any potential conflict. Add definition of 
	NEWLIB_ENOSYS and use it in place of ENOSYS.

2002-04-22  Jonathan Larmour  <[e-mail]>

	* doc/redboot.sgml: Document iq80321 switch settings.

	* include/redboot.h: Add gettimeofday, rename, isatty and system
	syscall numbers.
	
	* src/syscall.c (__do_syscall): Handle above new syscalls in a
	"default" way.
	Take new extra signal argument.
	When required, handle file I/O syscalls, by passing into HAL.

2002-04-21  Paul Fine  <[e-mail]>

	* src/flash.c (flash_get_config, load_flash_config): Save a
	pointer to the configuration structure in FLASH.  If
	flash_get_config fails to find a config item, check to make sure
	that the config structure in RAM has not been trashed.  If it has
	been trashed, set the pointer to the "readonly" version in FLASH
	and try to read the config item again.
	
	* cdl/redboot.cdl (CYGSEM_REDBOOT_FLASH_CONFIG_READONLY_FALLBACK):
	Added this flash config option to control the readonly fallback in
	flash.c

2002-04-16  Yoshinori Sato  <[e-mail]>
2002-04-16  Jonathan Larmour  <[e-mail]>

	* src/xyzModem.c: Don't return ACKs too early.

2002-04-16  Gary Thomas  <[e-mail]>

	* src/net/bootp.c: Readjust timeouts - more, shorter.  Better response.

2002-04-12  Gary Thomas  <[e-mail]>

	* src/net/bootp.c: Increase timeouts for slower networks.

2002-04-11  Nick Garnett  <[e-mail]>

	* doc/redboot.sgml: Changed some misplaced <term>s into
	<literal>s.

2002-04-08  Nick Garnett  <[e-mail]>

	layout and miscellaneous other fixes for 80321.

2002-04-03  Gary Thomas  <[e-mail]>

	* src/main.c (do_mfill):

2002-02-28  Hugo Tyson  <[e-mail]>

	* src/flash.c (do_flash_config): Add "-d" to the help info.

	* doc/redboot.sgml: Docuement the "-d" option for dumb terminals

	* include/redboot.h: Same.

2002-02-27  David Howells  <[e-mail]>

2002-02-26  David Howells  <[e-mail]>

	* doc/redboot.sgml: Updated the ASB2305 notes to be more complete
	with respect to having two flash chips.

2002-02-19  Mark Salter  <[e-mail]>

	* src/net/net_io.c (net_io_init): Remove ISR installation. This
	was wrong way to fix problem.

2002-02-15  Mark Salter  <[e-mail]>

	* src/net/net_io.c (net_io_init): Install default ISR for ethernet.

2002-02-14  Patrick Doyle  <[e-mail]>

	* src/fs/disk.c (disk_stream_read): Modified to return the number
	of bytes read instead of -1 when such number is less than was
	requested.
	
2002-02-06  Mark Salter  <[e-mail]>

	* src/syscall.c (sys_write): Call __flush after last __putc.
	(__flush): New function to flush console output.

2002-02-05  Jonathan Larmour  <[e-mail]>

	* src/net/net_io.c (net_init): Set use_bootp and net_debug defaults
	properly.

2002-01-31  Gary Thomas  <[e-mail]>

	* src/fs/ide.c (ide_packet_read_sectors): Pass errors on read.
	(ide_init): Ignore ATAPI devices that are not CDROM (like ZIP).

2002-01-30  Hugo Tyson  <[e-mail]>

	* src/net/net_io.c (start_console): Pick up config items to choose
	a console for special debug messages.  If it's not set, select
	channel 0 regardless, like it used to.
	(info_console_force, info_console_number): New fconfig options to
	control this channel *plus* forcing application special debug out
	to a particular serial.   This is crucial for debugging debugging
	itself, or debugging a networked app over the network when you're
	liable to get such messages popping out from the app as well as
	from RedBoot.

	* cdl/redboot.cdl (CYGDBG_REDBOOT_NET_DEBUG_CONSOLE_NUMBER):
	Option deleted, because this is now controlled by fconfig items.

2002-01-25  Hugo Tyson  <[e-mail]>

	* src/syscall.c (sys_profile_reset): New routine - doesn't do
	much, just NULLs the callback.  Useful placeholder in case more is
	needed in future, eg. reset the clock also.
	(__do_syscall): Calls the reset on syscall 2003.

2002-01-21  Hugo Tyson  <[e-mail]>

	* src/flash.c (do_flash_config): Enable a "dumb terminal" mode for
	fconfig, which does not pre-fill the buffer for editing, but
	merely prompts for a new value (or RET for old, for non-string
	values).  This is because telnet/kermit-like network terminal apps
	are not by default configured to pass all characters through.

2002-01-18  Hugo Tyson  <[e-mail]>

	* src/syscall.c (sys_timer_ticks): Change this to a cyg_uint64 to
	give better range for times() sanity in case we run the hardware
	clock ticking at a faster rate, or want to last > 8 days.

2002-01-16  Hugo Tyson  <[e-mail]>

	* src/syscall.c (sys_profile_frequency): Change frequency that is
	passed around to signed, so that we can enquire using -ve values.
	Re-order the logic a little so as to permit enquiries which do not
	modify what's set up in the hardware.  Adjust the times() counter
	when its HZ rate changes so it tells the truth.

2002-01-15  David Woodhouse  <[e-mail]>

	* src/flash.c: Better default for 'fis cr' - if we're programming
	an existing flash image, take img_size from the last-loaded image
	but length from the one that's already on the flash.
	
2002-01-14  David Woodhouse  <[e-mail]>

	* src/main.c: Useful defaults for cksum command.
	* src/flash.c: Useful defaults for fis create command.
	* src/load.c: Slight cleanup of file type detection.
	
2002-01-14  Jesper Skov  <[e-mail]>

	* src/net/cksum.c: Added volatile keyword to union members to
	prevent compiler optimization messing things up.

2002-01-10  Hugo Tyson  <[e-mail]>

	* src/syscall.c (sys_timer_isr): Add CYGARC_HAL_SAVE_GP(); and
	CYGARC_HAL_RESTORE_GP(); around the callback invocation to protect
	ourselves from whatever the app routine might do along those lines.

2002-01-10  Hugo Tyson  <[e-mail]>

	* src/syscall.c (sys_timer_ticks): Explicitly initialize this.
	(sys_timer_isr): Call periodic callback function, with PC and SP
	of interrupted context, if set.
	(sys_profile_call_back): New routine to support
	gprof profiling of GNUPro/newlib apps via BSP_SYSCALLS.  Sets the
	periodic callback function, returning the old value.
	(sys_profile_frequency): Ditto, sets the frequency of the call, if
	possible, or zero => a mere inquiry.
	(sys_timer_init, sys_times): Be prepared for a dynamic non-default
	clock rate.
	(__do_syscall): Handle new case arms.

	* cdl/redboot.cdl (CYGSEM_REDBOOT_BSP_SYSCALLS): Changed to a
	component; want to add stuff in here later.
	(CYGSEM_REDBOOT_BSP_SYSCALLS_GPROF): New option
	to control inclusion of histogram profiling callback syscalls.

2002-01-10  Jesper Skov  <[e-mail]>

	* src/main.c (do_version): Added year 2002.

2002-01-07  Gary Thomas  <[e-mail]>

	* src/flash.c (lookup_alias): Remove warning.
