3eb90bad65 Generic udelay() with watchdog support
According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.

This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

d754902409 i386: Misc PCI fixups
Change PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY (Originally done in
commit ff4e66e93c, regressed by commit 6d7f610b09)

Cast PCI_ROM_ADDRESS_MASK to u32

Wrap probe_pci_video() call inside #ifdef CONFIG_VIDEO

Change call to pci_find_class() to pci_find_devices(). This is based on a
patch submitted on 1st March 2007 (Patch that fixes the compilation errors
for sc520_cdp board) by mushtaq_k

This patch requires that PCI_VIDEO_VENDOR_ID and PCI_VIDEO_DEVICE_ID be
specified in the board config file.  Dummy values have been added for the
SC520 CDP board to enable compilation, but since I do not have one of these,
I do know what the values should be

04ff9ab158 Fix sc520 timer interrupt generation
The current implementation has the timer being started before the interrupt
handler is installed. It the interrupt occurs before the handler is
installed, the timer interrupt is never reset and the timer stops

gcc 4.3.2 optimiser creates multiple copies of inline asm (who knows why)
Remove use of global names for labels to prevent 'symbol already defined'
