580ca3c2b1 ppc4xx: Kilauea: Add CPLD version detection and EBC reconfiguration
A newer CPLD version on the 405EX evaluation board requires a different
EBC controller setup for the CPLD register access. This patch adds a CPLD
version detection for Kilauea and code to reconfigure the EBC controller
(chip select 2) for the old CPLD if no new version is found.

Additionally the CPLD version is printed upon bootup:

Board: Kilauea - AMCC PPC405EX Evaluation Board (CPLD rev. 0)

eb20392ca9 ppc4xx: Fix sending type 1 PCI transactions
The list of 4xx SoCs that should send type 1 PCI transactions
is not defined correctly. As a result PCI-PCI bridges and devices
behind them are not identified. The following 4xx variants should
send type 1 transactions: 440GX, 440GP, 440SP, 440SPE, 460EX and 460GT.

57ab8a129d ppc4xx: Allow setting a single SPD EEPROM address for DDR2 DIMMs
On platforms where SPD EEPROM and another EEPROM have adjacent
I2C addresses SPD_EEPROM_ADDRESS should be defined as a single
element array, otherwise DDR2 setup code would fail with the
following error:

ERROR: Unknown DIMM detected in slot 1

However, fixing SPD_EEPROM_ADDRESS would result in another
error:

ERROR: DIMM's DDR1 and DDR2 type can not be mixed.

This happens because initdram() routine does not explicitly
initialize dimm_populated array. This patch fixes the problem.

of F and vice versa). This patch fixes this.

Versioning:
===========
Starting with the release in October 2008, the names of the releases
were changed from numerical release numbers without deeper meaning
into a time stamp based numbering. Regular releases are identified by
names consisting of the calendar year and month of the release date.
Additional fields (if present) indicate release candidates or bug fix
releases in "stable" maintenance trees.
U-Boot uses a 3 level version number containing a version, a
sub-version, and a patchlevel: "U-Boot-2.34.5" means version "2",
sub-version "34", and patchlevel "4".
Examples:
U-Boot v2009.11 - Release November 2009
U-Boot v2009.11.1 - Release 1 in version November 2009 stable tree
U-Boot v2010.09-rc1 - Release candiate 1 for September 2010 release
The patchlevel is used to indicate certain stages of development
between released versions, i. e. officially released versions of
U-Boot will always have a patchlevel of "0".
