CL4 - OFW - No fw version in ROM file

[chia-hsiu]

I found there is no fw version in rom file.
CL2 have this version name in address "f.ffc7" but nothing in CL4 rom file.
I know it may because the rom size has adjusted to 2MB, but I really need this fw version to compare with internal OFW version.
So I create a ticket to monitor.

The official and easy way to get the firmware version, which works on all machines, is to use the command

   ofw-version$  ( -- adr len )

For example:

   ok ofw-version$ type

I mean fw version in ofw image, we used to use below code to check firmware up to date or not.

   " u:\cl4fw.zip" expand$
   ['] (boot-read) catch  if  2drop exit  then
   img$  firmware-up-to-date?  if
      cr
      ." The current version of the OFW is newer then upgrading file!" cr
      ." Continuing with current firmware!" cr
      exit
   then
   img$ do-ofw-update

cl4fw.zip contain a OFW image which rename to data.img.
Inside word ((fw-version)) , it will consider this image is invalid because f.ffc7 has no version name.

Was because f.ffc7 was used instead of new signature-offset, and for CL4 the offset has changed. Fixed in svn 3285.
