The get_clock_freq() comes from freescale/common/cadmus.c and is

the meantime, tie it to CONFIG_SYS_CLK_FREQ like all the other

sbc8548: delete unused MPC8548CDS info carried over from port
There are a couple defines and PCI bridge quirks related to the PCI
backplane of the MPC8548CDS that have no meaning in the context of
the port to the sbc8548 board, so delete them.
Also, the form factor of the sbc8548 is a standalone board with a
single PCI-X and a single PCI-e slot. That pretty much guarantees
that it will never be a PCI agent itself, so the host/agent and root
complex/end node distinctions have been removed.
Similarly, since there is no physical connector mapping to PCI2, so
all references of PCI2 in the board support files have been removed
as well.

ppc/85xx: add boot from NAND/eSDHC/eSPI support
The MPC8536E is capable of booting form NAND/eSDHC/eSPI, this patch
implements these three bootup methods in a unified way - all of these
use the general cpu/mpc85xx/start.S, and load the main image to L2SRAM
which lets us use the SPD to initialize the SDRAM.
For all three bootup methods, the bootup process can be divided into two
stages: the first stage will initialize the corresponding controller,
configure the L2SRAM, then copy the second stage image to L2SRAM and
jump to it. The second stage image is just like the general U-Boot image
to configure all the hardware and boot up to U-Boot command line.
When boot from NAND, the eLBC controller will first load the first stage
image to internal 4K RAM buffer because it's also stored on the NAND
flash. The first stage image, also call 4K NAND loader, will initialize
the L2SRAM, load the second stage image to L2SRAM and jump to it. The 4K
NAND loader's code comes from the corresponding nand_spl directory, along
with the code twisted by CONFIG_NAND_SPL.
When boot from eSDHC/eSPI, there's no such a first stage image because
the CPU ROM code does the same work. It will initialize the L2SRAM
according to the config addr/word pairs on the fixed address and
initialize the eSDHC/eSPI controller, then load the second stage image
to L2SRAM and jump to it.
The macro CONFIG_SYS_RAMBOOT is used to control the code to produce the
second stage image for all different bootup methods. It's set in the
board config file when one of the bootup methods above is selected.

This is a first step towards reorganizing the mkimage code to make it

code is specific to generating uImage and FIT image files, but the
same framework can be used to generate other image types like
Kirkwood boot images (kwbimage-TBD). For this, the mkimage code gets
reworked:
Here is the brief plan for the same:-
a) Split mkimage code into core and image specific support
b) Implement callback functions for image specific code
c) Move image type specific code to respective C files
Currently there are two types of file generation/list
supported (i.e uImage, FIT), the code is abstracted from
mkimage.c/.h and put in default_image.c and fit_image.c;
all code in these file is static except init function call
d) mkimage_register API is added to add new image type support
All above is addressed in this patch
e) Add kwbimage type support to this new framework (TBD)
