The AppliedMicro APM8018X embedded processor targets embedded applications that
require low power and a small footprint. It features a PowerPC 405 processor
core built in a 65nm low-power CMOS process with a five-stage pipeline executing
up to one instruction per cycle. The family has 128-kbytes of on-chip memory,
a 128-bit local bus and on-chip DDR2 SDRAM controller with 16-bit interface.

This renames pci flags functions and enums in preparation for creating
generic version in asm-generic/pci-bridge.h. The following search and
replace is done:

s/ppc_pci_/pci_/
s/PPC_PCI_/PCI_/

Direct accesses to ppc_pci_flag variable are replaced with helper
functions.

This patch adds of_flat_dt_match() which tests a node for
compatibility with a list of values and converts the relevant powerpc
platform code to use it.  This approach simplifies the board support
code a bit.

This patch adds support for the ESTeem 195E Hotfoot SBC.

There are several variants of the SBC deployed, single/dual
ethernet+serial, and also 4MB/8MB flash variations.  In the interest of
having a single kernel image boot on all boards, the cuboot shim detects
the differences and mangles the DTS tree appropriately.

With the exception of the CF interface that was never populated on
production boards, this code/DTS supports all boardpop options.

Currently there are a number of platforms that open code access to
the ppc_pci_flags global variable.  However, that variable is not
present if CONFIG_PCI is not set, which can lead to a build break.

This introduces a number of accessor functions that are defined
to be empty in the case of CONFIG_PCI being disabled.  The
various platform files in the kernel are updated to use these.

This adds a common board file for almost all of the "simple" PowerPC 40x
boards that exist today.  This is intended to be a single place to add
support for boards that do not differ in platform support from most of the
evaluation boards that are used as reference platforms.  Boards that have
specific requirements or custom hardware setup should still have their own
board.c file.

The first board ported to this is the AMCC PowerPC 405EZ Acadia board.

The Arches Evaluation board is based on the AMCC 460GT SoC chip.
This board is a dual processor board with each processor providing
independent resources for Rapid IO, Gigabit Ethernet, and serial
communications.  Each 460GT has it's own 512MB DDR2 memory, 32MB NOR FLASH,
UART, EEPROM and temperature sensor, along with a shared debug port.
The two 460GT's will communicate with each other via shared memory,
Gigabit Ethernet and x1 PCI-Express.
