fbdev: extract fb_show_logo_line()
The Cell Broadband Engine contains a 64-bit PowerPC core with 2 hardware
threads (called PPEs) and 8 Synergistic Processing Engines (called SPEs).
When booting Linux, 2 penguins logos are shown on the graphical console by
the standard frame buffer console logo code.
To emphasize the existence of the SPEs (which can be used under Linux), we
added a second row of (smaller) helper penguin logos, one for each SPE.
A sample screenshot can be found at
http://www.kernel.org/pub/linux/kernel/people/geoff/cell/debian-penguin-shot.png
(or on the ps3linux T-shirts we wore at OLS :-)
This patch:
Extract the code to draw one line of logos into fb_show_logo_line()
