The current logo code is messy, complex, and inflexible. So I decided to
rewrite it. My goals were:
  - Logos must be accessible easily by an image editor (currently: hex C source
    data must be converted to another format first)
  - Logos must be stored in ASCII-form in the source tree
  - Support arbitrary logo sizes (currently: fixed 80x80)
  - Allow the logo to be selected statically (at compile time) and/or
    dynamically (at run-time, based on machine type) (currently: at compile
    time only).
  - Allow simple adition of new logos
  - Support grayscale logos (not used yet)

The patch achieves all of these. Logos are stored in ASCII PNM format in
drivers/video/logo/, and automatically converted to hex C source arrays using
scripts/pnmtologo. I chose ASCII PNM because (a) it's ASCII, (b) it's very
simple to parse without an external library (XPM is more difficult to parse),
and (c) it can be handled by many image manipulation programs.

Code that wants to display a logo just calls fb_find_logo(), specifying the
wanted logo type, and receives a pointer to a suitable logo (or NULL).

I also modified fb_show_logo() to return the number of scanlines that are used
by the logo, so fbcon knows how many lines to reserve.

I put a new version at

    http://home.tvd.be/cr26864/Linux/fbdev/linux-logo-2.5.59.diff.bz2

Changes:
  - Merge with 2.5.59
  - New logo (CLUT224 only) for PA-RISC
  - Let hgafb and newport_con include logo sources directly, since they need
    access to the logos in non-init code

All comments are welcomed! Thanks!

Come on, is there really no one to comment on this??
