a128b33b8b The VPD engine is broken and can't actually handle placing VPD 
anywhere other than offset 0 within the EEPROM, so we have to put our
settings at 0x100 instead.

6a91a03409 Added options listed in 
http://www.microsoft.com/whdc/winlogo/hwrequirements.mspx as required
for iSCSI boot.  Note that options 204-206 are listed in the document
but don't seem to be defined anywhere on the web.

c6060a8fea Tidy up some more output. The command-line code needs some severe 
overhauling, but this is not the time to do it.

8bff0f0619 Avoid draining the keyboard buffer during gateA20_set(). It shouldn't 
technically be necessary, because the "enable A20" command requires
only that the keyboard controller is ready to accept input (i.e. that
its input buffer is empty), and shouldn't also require that the
keyboard is ready to send output (i.e. that its output buffer is also
empty).  See http://www.smsc.com/main/tools/io-bios/42i.pdf section
3.1 ("Command Invocation") for a justification.

gateA20_set() is called on every real-mode transition (in case some
idiot piece of external code such as Intel's PXE stack decided it
would be fun to re-disable A20), so draining the keyboard buffer means
that we end up losing keypresses on some systems.  In particular, this
makes typing at the command line almost impossible, and causes
Etherboot to ignore Ctrl-Alt-Del.

We should really implement a gateA20_test() function to verify that
gate A20 has been correctly enabled, and think about adding other
commonly-used methods such as Fast Gate A20.

052ef6dc5a Added nvs_write(). This shares a lot of code in common with nvs_read(); 
this can probably be optimised down quite a lot.

Michael Brown
946967f09c Abstracted out part of the concept of an SPI device to a generalised NVS 
device.

Separated the mechanisms of non-volatile storage access and non-volatile
stored options.

dc06c895fc Changed length parameter in SPI methods to be a byte length, rather than 
a word length.

Michael Brown
931f94dca3 Generalised the SPI abstraction layer to also be able to handle interfaces 
that don't provide the full flexibility of a bit-bashing interface.

Temporarily hacked rtl8139.c to use the new interface.

82342e0b8f Marked memcmp/strcmp as "pure" functions, to allow gcc to optimise 
away code such as

  if ( strcmp ( some_string, "some_value" ) != 0 ) {
     DBG ( "Bad value received!" );
  }

Michael Brown
d37f82509f Added debug statements. 
Don't crash when called on an uninitialised chap structure; this
allows us to avoid extra checks within iscsi.c to make sure that we
receive the CHAP_XXX keys in a sensible order.

57d539aab0 Made it temporarily possible to call MD5 routines directly from external 
code, rather than going through the digest layer.

Removed a spurious line of constants.

65ff5357f1 Extend strtoul() to cope with hex as well as decimal. Doesn't cope 
with octal yet, but we can probably live without that.

b16de6ae66 Inhibit compiler warnings on DBG() when building a non-debug object, 
while retaining the format string checking.
 2006-09-27 11:09:56 +00:00

88e38fa148 We don't actually have a stdio.h header file. Our printf() functions are 
defined in vsprintf.h.  (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)

There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.

a3d508b648 Clarified packet ownership transfer between a few functions. 
Added a large number of missing calls to free_pkb().  In the case of UDP,
no received packets were ever freed, which lead to memory exhaustion
remarkably quickly once pxelinux started up.

In general, any function with _rx() in its name which accepts a pk_buff
*must* either call free_pkb() or pass the pkb to another _rx() function
(e.g. the next layer up the stack).  Since the UDP (and TCP) layers don't
pass packet buffers up to the higher-layer protocols (the
"applications"), they must free the packet buffer after calling the
application's newdata() method.

254fe6e00e Split DHCP packet creation into two parts: creating the basic packet
