[3c90xutil] Update bromutil.c and cromutil.c.

Browse Source 
bromutil.c has been updated with a command to "fix" 3c905B NICs
so that EEPROMs larger than 8K may be used.

cromutil.c has been replaced with an updated version that has been
included in etherboot-5.4 for some time now.

See README for usage.

replace cromutil.c. I will rename cromutil.c to ocromutil.c

Dear Marty,
Below you will find a new version of the cronutil.c program. Since
the changes were quite large I am sending the program rather than a patch.
I added support for 3C905CX cards with a page-mode super-flash EEPROM, and
included several informative messages, a programming progress report and a
detailed help message. I did all the tests I could with it and it seems to
work correctly for the 3C905CX with either type of EEPROM chip.
A question: is there a similar program for Intel eepro100 cards or for the
Intel or 3COM Gbit cards?
Cheers,

12/4/2009 The new cromutil version from Jorge L. deLyra can be found in
cromutil.c, whereas the old version can be found in ocromutil.c.
bromutil.c now supports enabling a bootrom workaround that was previously
implemented in the old 3c90x driver. Some 3c90xB cards refuse to load gPXE
after the ROM is burned. The gPXE banner is likely to appear, but gPXE will
crash soon after.
If this is the case try the following commands. It is assumed that you replace
0x6600 with the I/O address of your card which can be acquired with:
(look for a line like 'I/O ports at e400')
$ lspci -v
$ make
$ ./bromutil 0x6600 bootrom
This command will write into the settings EEPROM of the network card. In case
the network card shows any unexpected behavior it is possible to restore the
EEPROM settings with a 3COm provided tool called '3c90xcfg.exe'(google it for
mirrors).

Be careful. You can easily erase your Flash memory using these
utilities. Make *sure* to back them up first using the "read"
command. You must "erase" before using "prog" to program the chip with
