5bf5250e9d spl: make image arg or fdt blob address reconfigurable
At present fdt blob or argument address being passed to kernel is fixed at
compile time using macro CONFIG_SYS_SPL_ARGS_ADDR. FDT blob from
different media like nand, nor flash are copied to the address pointed
by the macro.
The problem is, it makes args/fdt blob compulsory to copy which is not required
in cases like for NOR Flash. This patch removes this limitation.

ebc4ef61d7 spl: Add a name to the SPL load-image methods
It is useful to name each method so that we can print out this name when
using the method. Currently this happens using a separate function. In
preparation for unifying this, add a name to each method.

The name is only available if we have libcommon support (i.e can use
printf()).

2a2ee2ac35 spl: Pass spl_image as a parameter to load_image() methods
Rather than having a global variable, pass the spl_image as a parameter.
This avoids BSS use, and makes it clearer what the function is actually
doing.

ecdfd69a4b spl: Convert boot_device into a struct
At present some spl_xxx_load_image() functions take a parameter and some
don't. Of those that do, most take an integer but one takes a string.

Convert this parameter into a struct so that we can pass all functions the
same thing. This will allow us to use a common function signature.

5aa79f2676 spl_nor.c: Support devicetree sizes different from 16k
The devicetrees for various platforms already exceed 16k. Add a define
CONFIG_SYS_FDT_SIZE to specify the FDT size, and set to 16k for the
two boards that define this CONFIG_SYS_FDT_BASE parameter. This
allows platforms with larger devicetree blobs to boot from NOR.

7e0f22674a SPL: Let spl_parse_image_header() return value
Allow the spl_parse_image_header() to return value. This is convenient
for controlling the SPL boot flow if the loaded image is corrupted.

36afd45136 spl: change return values of spl_*_load_image()
Make spl_*_load_image() functions return a value instead of
hanging if a problem is encountered. This enables main spl code
to make the decision whether to hang or not, thus preparing
it to support alternative boot devices.

Some boot devices (namely nand and spi) do not hang on error.
Instead, they return normally and SPL proceeds to boot the
contents of the load address. This is considered a bug and
is rectified by hanging on error for these devices as well.

9f9d8704b6 spl: spl_nor: surround Linux-load code with #ifdef CONFIG_SPL_OS_BOOT
If CONFIG_SPL_NOR_SUPPORT is defined, spl_nor_load_image() requires
spl_start_uboot(), CONFIG_SYS_OS_BASE, CONFIG_SYS_SPL_ARGS_ADDR,
CONFIG_SYS_FDT_BASE to be defined even if users just want to run
U-Boot, not Linux.  This is inconvenient.

This patch is following the codying style of common/spl/spl_nand.c.

33d346464a SPL: Add NOR flash booting support
SPL NOR flash booting support is quite simple. Only copying of the
images is needed.

On MPC5xxx we need to make sure to only use the standard memcpy()
implementation and not the MPC5xxx specific one. As the MPC5xxx
version has some complexity which is not needed for this SPL
booting.
