[Etherboot-developers] Etherboot 4.7.20 (development) released

[Ken Y. <ke...@nl...>]

I have released Etherboot 4.7.20 at http://etherboot.sourceforge.net/

We can probably start the 5.0 release candidate countdown from .21 so
please give this a good workout. I'd like to work on the documentation
now so send in any patches you like to see to the text.

Innovations, sorry changes, in this release:

+ Donald Christensen completed the translation of loader.S and all the
other .S files in the src directory that previously required as86 or
nasm. No more futzing around with precompiled versions. Yipee!

+ Luigi Rizzo contributed a slightly hacked FreeBSD loader that works on
floppy or hard disk. See boot1a.s for details. Makefile rules edited.
Targets renamed .dsk and .lzdsk to indicate they're not floppy specific
now. Documentation updated. I note that the loader is smart enough to
figure out exactly how many sectors have to be read.

+ Renamed comload.S to comprefix.S which describes it better.

+ mknbi tools split out into separate package for independent
development.

+ Use A32 instead of Z32 in unpack format in disrom.pl in case we
encounter old Perl versions (< 5.005).

+ Vendor Class Identifier string that's sent out is now of the form
Etherboot-x.y (13 bytes long).

+ Reduced size of ee_data in davicom.c to 32 bytes because we only need
to access the MAC address in bytes 20:25.

+ Changed type of formal arguments to pci.[ch] routines to unsigned int
except for the last argument, because in ANSI C parameter passing is
like assignment and extra dummy variables and code may need to be
generated if the formal argument type is not the the same size as the
actual argument that gets pushed on the stack. Not insignificant
overhead, reduction from 1853 to 1727 bytes due to change. Changed devfn
and bus members of struct pci_device to unsigned char to enforce limit
on type. Surprisingly this reduced the size further to 1667 bytes.
Probably the compilier could do more optimisations after the last
change.

+ Some drivers hardwired 0 for bus number in calls to pcibios_*
functions. Changed to pci->bus, which is set in scan_bus. Only
people with NICs not on bus 0 would have noticed.

+ Found a couple more old-style pre-ANSI C function declarations. Turned
on -ansi and -pedantic for kicks and fixed some non-ANSIness, e.g.
// comment in #define, text after #endif, casting memcpy arguments to
void *, using void * instead of char *. Some char declarations changed
to unsigned char.
