017e0fad3e [PATCH] powerpc: fixing compile issue with !CONFIG_PCI in legacy_serial.c
Only build in support for ISA and PCI cases if we have enabled CONFIG_ISA
and CONFIG_PCI.  Additionally, isa_bridge is a global so we shouldn't use
it a parameter name since it gets redefined to NULL when !CONFIG_PCI.

b580d46ce8 [PATCH] powerpc: Add the ability to handle SOC ports in legacy_serial
Add the ability to configure and initialize legacy 8250 serials
ports on an SOC bus.  Also, fixed an issue that we would not
configure any serial ports if "linux,stdout-path" was not found.

d2dd482bc1 [PATCH] powerpc: Update OF address parsers
This updates the OF address parsers to return the IO flags
indicating the type of address obtained. It also adds a PCI
call for converting physical addresses that hit IO space into
into IO tokens, and add routines that return the translated
addresses into struct resource

This makes it deal with the fact that the Pegasos firmware reports that
its clock frequency is zero...

463ce0e103 [PATCH] powerpc: serial port discovery (#2)
This moves the discovery of legacy serial ports to a separate file,
makes it common to ppc32 and ppc64, and reworks it to use the new OF
address translators to get to the ports early. This new version can also
detect some PCI serial cards using legacy chips and will probably match
those discovered port with the default console choice.

Only ppc64 gets udbg still yet, unifying udbg isn't finished yet.

It also adds some speed-probing code to udbg so that the default console
can come up at the same speed it was set to by the firmware.
