Corrected IRQ triggering and level settings according to latest revision
of the 440EP User Manual (rev 1.24 nov 16, 2007).
The incorrect settings might cause a failure of the network if both
onchip ethernet ports are under heavy load.

The ml300 and ml403 xparameters.h files use different macros for the
AC97 interrupt pin assignments. This normalizes them to a canonical
value similar to what EDK generates for most other devices. This is
needed to get ml300 support to compile in arch/ppc.

On 4xx CPUs, the current implementation of flush_tlb_page() uses
a low level _tlbie() assembly function that only works for the
current PID. Thus, invalidations caused by, for example, a COW
fault triggered by get_user_pages() from a different context will
not work properly, causing among other things, gdb breakpoints
to fail.
This patch adds a "pid" argument to _tlbie() on 4xx processors,
and uses it to flush entries in the right context. FSL BookE
also gets the argument but it seems they don't need it (their
tlbivax form ignores the PID when invalidating according to the
document I have).

Why create a platform specific board_info structure that is hacked

The arch/ppc/syslib/ppc_sys.c infrastructure does not work well for the

Reverse dependency order for Xilinx Virtex parts. For these parts, It
makes more sense for boards/chips to specify which features they
provide instead of the features listing the parts they are implemented
in. I think it also makes adding new board ports simpler.

Lifted from http://bugzilla.kernel.org/show_bug.cgi?id=8182
Steps to reproduce:
- Boot an Ocotea board with the mainline 2.6.20.1 kernel.
- Create an /etc/ntp.conf file with at least one NTP server and iburst mode set.
- Issue the command "ntpd -g".
- Wait about two minutes.
- Verify ntpd's status via "ntpq -pn" and by looking in /var/log/ntp.
This fixes this problem by adjusting the expected clock frequency.

This patch adds support for the AMCC Taishan PPC440GX evaluation
board.
This is still an arch/ppc port. I'm aware that the move of
4xx to arch/powerpc is making good progress right now. So this
patch is mainly intended to make the Taishan support available
for the community right now.

Hi,
this patch brings the CPCI405 board support up to date and fixes several
outstanding issues:
-add bios_fixup()
-enable RTC only when CONFIG_GEN_RTC defined
-corrected CompactPCI interrupt map
-added cpci405_early_serial_map for correct UART clocking
-removed unused code

This patch adds workaround for PPC 440GX erratum 440_43. According to

happen during DataTLB miss processing. We disable L1 cache parity
