eCos/RedBoot for勤研ARM AnywhereII(4510) 含全部源代码

	* src/fs/ide.c: Improve IDE handling by having init function return
	actual number of controllers detected.  This avoids really long times
	for startup if the controller is missing.

	* src/net/bootp.c: Rework to use full DHCP protocol.  Previously,
	once an offer came in, RedBoot was happy, without actually making
	the address reservation and waiting for the final acknowledgement.
	Also, added CDL to enable/disable DHCP.  BUG #1000053

2003-09-20  Chris Garry  <[e-mail]>
	
	* src/main.c: Modified the way multiple "RAM" segments are reported.

	* src/fconfig.c: Variables 'stat' and '*err_addr' in function
	flash_write_config() are now defined regardless of whether 
	CYGSEM_REDBOOT_FLASH_COMBINED_FIS_AND_CONFIG is defined of not.

2003-09-19  Gary Thomas  <[e-mail]>

	* src/net/timers.c (__timer_poll): Need to call MS_TICKS_DELAY() or
	else time will never progress.  This can cause a missed TCP packet
	to cause the stack to freeze.  BUG #23006

	* src/net/tftp_client.c: Make timeout on very first transaction really
	long - again since some servers are just slow/ill mannered.

	* src/net/net_io.c: Allow default server IP to be always enabled, thus
	it can override what is provided by BOOTP/DHCP (since some DHCP servers
	don't provide this properly).

	* src/time_date.cxx: New file - support "date" command for platforms
	with battery backed up clocks.

	* src/fconfig.c: New file - split out from flash.c

	* src/main.c: 
	* src/load.c: 
	* src/flash.c: 
	* src/alias.c: 
	* include/redboot.h: 
	* cdl/redboot.cdl: Support multiple "RAM" segments (known writable
	memory).  Also rearrange FLASH & FCONFIG, separating them as much
	as possible and supporting FCONFIG data stored in some other sort
	of device, like EEPROM.

2003-09-09  Gary Thomas  <[e-mail]>

	* src/flash.c (flash_config_insert_value): Default value was
	wrong for ESA type.

2003-09-08  David Vrabel  <[e-mail]>

	* src/net/bootp.c (__bootp_find_local_ip): Adds Option 55 Parameter
	Request List) to the DHCP request (requests: Subnet Mask; Router;
	Domain Name server).

2003-08-19  Gary Thomas  <[e-mail]>

	* src/net/udp.c (__udp_recvfrom): Rework loop so delay only happens
	if no packet is immediately available - improves network throughput.

	* src/ticks.c: 
	* cdl/redboot.cdl: Add control over granularity of timers used
	by RedBoot and the network stack.

2003-08-05  Jonathan Larmour  <[e-mail]>

	* doc/redboot_installing.sgml: Fix brain fart in last change to
	AT91 instructions. Also clarify instructions a bit, including
	documenting better for windows users.

2003-07-23  Patrick Doyle  <[e-mail]>

	* src/flash.c (fis_find_free)
	* src/flash.c (fis_free): Do not search areas reserved for RedBoot
	when scanning for free space.

2003-07-16  Gary Thomas  <[e-mail]>

	* src/net/ping.c:
	* src/net/bootp.c: Allow ^C to abort.

	* src/io.c: 
	* include/redboot.h: New function _rb_break() used to test for ^C
	on the console.  Used to break out of long operations like BOOTP.

2003-07-15  Gary Thomas  <[e-mail]>

	* src/net/bootp.c: Use correct options for DHCP discover.  This has
	the added bonus that when BOOTP & GATEWAY options are enabled, then
	RedBoot can get it's address via normal DHCP.  Of course, DHCP leases
	will be ignored by RedBoot, so some caution is warranted.

	* include/net/net.h: 
	* src/net/arp.c (__arp_request): Allow ARP of self - used during
	initialization to "broadcast" that an IP address is in use.

	* src/net/net_io.c (net_init): When using a static IP, send an
	initial ARP to see if any other node is using this address.
	Also, some minor cosmetic cleanups to remove warnings.

2003-07-15  Jonathan Larmour  <[e-mail]>

	* doc/redboot_installing.sgml (AT91): Tell users to switch JP1
	(or SW1 for EB40) when installing, and warn them in no
	uncertain terms the consequences of failing to do so.

2003-07-01  Mark Salter  <[e-mail]>

	* cdl/redboot.cdl (CYGBLD_BUILD_REDBOOT_WITH_MCOPY): New option.
	* src/mcopy.c: New file adding mcopy command.
	* doc/redboot_cmds.sgml: Add mcopy.

2003-06-26  Jonathan Larmour  <[e-mail]>

	* doc/redboot_installing.sgml: Clarify use of correct cables with
	serial ports with AT91 boards.

2003-06-24  Jonathan Larmour  <[e-mail]>

	* doc/redboot_cmds.sgml (IP): Clarify last change a bit and fix typos
	and markup.

2003-05-20  David Vrabel  <[e-mail]>
2003-05-20  Ian Campbell  <[e-mail]>
 
	* src/net/net_io.c: Add the ability to specify a netmask length to
	the ip_address command
	* doc/redboot_cmds.sgml: Document the above.

2003-06-24  Jeroen Dobbelaere  <[e-mail]>
2003-06-24  Jonathan Larmour  <[e-mail]>

	* src/net/tftp_client.c: Define tftp_stream.last_good_block to
	permit downloads > 32MB.
	(tftp_ack): Allow last_good_block to wrap.

2003-05-13  Nick Garnett  <[e-mail]>

	* doc/redboot_installing.sgml: Added installation instructions for
	Atmel EB40A, EB42 and EB55 boards.

2003-05-06  Mark Salter  <[e-mail]>

	* src/main.c (cyg_start): Clear gdb_active when returning from stub.

2003-05-06  Pierre Habraken  <[e-mail]>

	* cdl/redboot.cdl: Added option
	CYGOPT_REDBOOT_BSP_SYSCALLS_EXIT_WITHOUT_TRAP for enabling (possibly
	single shot) programs to exit and return a termination status as
	their normal behavior (i.e. without raising a SIGTRAP).
	* src/syscall.c (__do_syscall): Added conditionally compiled code
	to SYS_exit for returning to RedBoot main loop without raising a
	SIGTRAP, even when the calling program is not being debugged.
	* src/main.c (cyg_start): Added code (following Jonathan Larmour's
	and Mark Salter's suggestions) to RedBoot main loop: a (context)
	savepoint is created before the thread of control is transferred to
	gdb stubs (through a trampoline procedure). This savepoint enables
	the stubs to return control back to the main loop by calling the
	return_to_redboot procedure (macro CYGACC_CALL_IF_MONITOR_RETURN).
	Procedure go_trampoline and variables go_saved_context and
	go_return_status have been respectively renamed	to trampoline,
	saved_context and return_status.

2003-04-23  Chris Garry <[e-mail]>

2003-04-18  Gary Thomas  <[e-mail]>

	* src/net/tftp_client.c: Arrange to ACK last good packet when closing.
	Without this, the host can be left tryint to send that packet forever.

2003-04-14  Jani Monoses  <[e-mail]>	
	
	* src/load.c:
	Change #else if to #elif so it compiles when TFTP is disabled.
