Strange OF display while booting

Strange OF display while booting

[Michel Lanners]

Hi all,

With recent BenH kernels, the early boot messages (before switching to
aty128fb in my case) are messed up. The first few messages start in the
middle of the top row, with some white areas to the left of the
messages, then at the middle hight of the screen there's a white area
spannig all the width, and below that the text messages are aligned
correctly again to the left edge of the screen.

FWIW, this was not the case with older kernels (2.4.5-pre3 comes to
mind).

Maybe somenody will know what changed...

Michel

That code have been hacked a bit by both paulus and me lately. Can
you try out my current rsync ?

There were several issue, including some miscalculation of the display
BAT, and some problems writing to some old machine framebuffer with
cache enabled. I moved out the bootx text from prom.c and now start
displaying things only in platform_init (where we have the display BAT
set to non-cachable).

Ben.
