Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] m68knommu: configurable frequency selection header Remove list of fixed clock frequency options used for configuring master clock, and make field an int. Much more flexible this way, no need to add more options for every new used freqency. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

m68knommu: clean up definitions of ColdFire peripheral base registers Different ColdFire CPUs have different ways of defining where their internal peripheral registers sit in their address space. Some use an MBAR register, some use and IPSBAR register, some have a fixed mapping. Now that most of the peripheral address definitions have been cleaned up we can clean up the setting of the MBAR and IPSBAR defines to limit them to just where they are needed (and where they actually exist).

m68knommu: make ColdFire internal peripheral region configurable Most ColdFire CPUs have an internal peripheral set that can be mapped at a user selectable address. Different ColdFire parts either use an MBAR register of an IPSBAR register to map the peripheral region. Most boards use the Freescale default mappings - but not all. Make the setting of the MBAR or IPSBAR register configurable. And only make the selection available on the appropriate ColdFire CPU types. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
