基于ecos的redboot

2000-09-11  Jonathan Larmour  <[e-mail]>

	* include/redboot.h (_RedBoot_init): Define tables entries as structs
	with one member rather than just func ptrs, to enforce alignment rules
	* src/main.c (cyg_start): Change to use struct init_tab_entry per above

2000-09-07 Andrew Lunn  <[e-mail]>

	* src/load.c, include/redboot.h: renamed the getc functions to
 	redboot_getc and made them global so custom boot loaders can use
 	them.

2000-09-06  Gary Thomas  <[e-mail]>

	* doc/users_guide: Add info about region locking/unlocking.

2000-09-04  Jonathan Larmour  <[e-mail]>

	CYG_HAL_TABLE_TYPE
	* include/redboot.h: Ditto for struct cmd and void_fun_ptr	

2000-09-01  Hugo Tyson  <[e-mail]>

	* src/flash.c: CYGHWR_IO_FLASH_BLOCK_LOCKING is an interface, so
	it's always defined; look for > 0 instead.

	* src/flash.c: Support block locking if available.

2000-08-25  Gary Thomas  <[e-mail]>

	* src/io.c (dump_buf_with_offset): Clean up warnings.

	* src/net/net_io.c: Cosmetic - clean up TCP debug code.

	* src/main.c (cmd_search): Search for ambiguous commands was
	wrong since layout change (only know the limits, don't rely

	particular, commands and platform initializations can now
	be handled via anonymous tables.

	and settable in FLASH.  Better handling of GDB $O packets (less
	latency).  Additional small changes to support network debug.

2000-07-30  Gary Thomas  <[e-mail]>

	* src/flash.c: Make config data safer with a 'key'.  Also, don't
	erase the config data when doing a full FIS initialization.
	Finally, ensure that the commands which erase data are not going
	to erase the current code!

	* src/load.c: Add '-raw' switch to allow loading a file without
	trying to interpret it as an executable image.

	* src/main.c: 
	* src/redboot.h: Make command parsing functions public.

2000-07-29  Gary Thomas  <[e-mail]>

	* src/net/bootp.c: Turn on network debug during address discovery.
	(Note: this will be optional/configurable in the future).

	* src/net/eth_drv.c: Use 'net_debug' for diagnostic dumps.

	* src/redboot.h: Prototypes for new functions.

	* src/printf.c (vprintf): New function.

	* src/io.c (verify_action): New function.

	* cdl/redboot.cdl: Make FLASH support optional.

	* cdl/redboot.cdl: 
	* src/redboot.h: 
	* src/main.c: 
	* src/io.c: 
	* src/net/net_io.c: Support "floating" console, chosen from
	available serial I/O channels.

2000-07-26  Gary Thomas  <[e-mail]>

	* src/net/tftp_support.h: 
	* src/net/tftp_client.c: Add new stream oriented functions.

	* src/net/net.h: More prototypes.

	* src/redboot.h: Move support functions here.  Update interfaces.

	* src/printf.c: Support %l (long) qualifier.

2000-07-22  Gary Thomas  <[e-mail]>

	* src/main.c (do_load): Add proper argument parsing.

2000-07-21  Gary Thomas  <[e-mail]>

	* src/io.c (gets): Treat "\n\r" and "\r\n" as exactluy "\n".  This
	solves problems of simply ignoring "\n" on terminals which can only
	send that character while still working with telnet/TCP connections.

	* src/net/net_io.c: New file.  Supports local I/O via a TCP channel.
	Additional changes to support TCP channel for GDB debug I/O.

	* cdl/redboot.cdl: Clean up dependencies.  Extend network configuration.

	* src/io.c (gets): Ignore blank lines which contain only '\n'.
	This works fine for terminal I/O since they will have '\r' and it
	allows reasonable handling when connected via telnet/TCP.

	* src/main.c: Better support for network connections.  
	Also some reworking of FLASH routines [will be moved later].  
	More error checking and better error messages in download code.

	* src/net/net.h: Reorder 'tcp_socket' fields to enforce proper
	alignment of data buffer [needs to be on dword boundary].

	* src/net/tcp.c: Many small changes getting 'endian'-ness correct.

	* src/net/tftp_client.c (tftp_error): New function - returns a
	string representing the error code [for humans].

2000-07-16  Gary Thomas  <[e-mail]>

	* cdl/redboot.cdl: Make network support configurable/optional.

	* src/io.c: Add command line input function.

	* src/main.c: Lots of new functions, command line processing, etc.

	* src/misc_funs.c (strcmp, strncmp): New function(s).	

	* src/printf.c: Add support for "%p" (pointers).

	* src/redboot.h: Expand, move global vars, here, etc.

	* src/net/eth_drv.c: Make quieter, change "no interface" string.

	* src/net/net.h (__LITTLE_ENDIAN__): Avoid redefining this on platforms
	where GCC does it for us.

2000-07-12  Gary Thomas  <[e-mail]>

	* cdl/redboot.cdl: New file(s).
