[U-Boot] [PATCH] MPC8308: Fixup clocks in PCI Host configuration

Not exactly unfortunately.  On the 8308s I currently have u-boot doesn't work
without this patch.  I believe before on the 8308 development
board I had the PCI_HOST bit of the HRCW_HIGH would latch when
set in the #define for CONFIG_SYS_HRCW_HIGH.  I don't have the old
development board any more, and my new board doesn't appear to latch
that bit.  I also don't know what rev of the microprocessor the old one was.

It is entirely possible some other change was made and this is a manifestation
of that change instead (I was playing around with the 8308 development
board in the u-boot 1.3.0 timeframe).

No.  Don't have the old test board anymore.  As such, I have
only verified it on the custom board I have currently.  I did try playing
with the CONFIG_SYS_HRCW_HIGH and setting the PCI_HOST bit
in my current board but that didn't fix it.

Out of curiousity, does anyone have one of the 8308_p1m and is the
current u-boot booting on it?  I can't figure out why it would work on
the p1m and not my board.

Yea.  Sorry about that.  Fixed in V2 patch.

Thanks!
