If you want to inspect the control device tree using the fdt command,
the "fdt address -c" command previously unhelpfully printed the phys
memory address of the device tree. That address could not then be used
to set the fdt address for inspection. Changed the resulting print to
one that can be copied directly to the 'fdt address <addr>' command.

This allows to first read the IVM content (earlier in the boot sequence)
and define the ethaddr env variable thanks to the ivm_read_eepromi().
Later, the IVM content can be parsed and used to define some hush
variables, when the hush subsystem is available thanks to
ivm_analyze_eeprom().
To avoid the HW read to happen twice, the buffer passed to
ivm_read_eeprom() has to be reused by ivm_analyze_eeprom (and thus
allocated before calling ivm_read_eeprom()).

So that the CONFIG_SPL_FEL option is not needed anymore. And the regular
SPL binary, generated by the default u-boot build, is now also bootable
over USB in the FEL mode. The SPL still can boot from the SD card too.
A bunch of system registers need to be saved/restored in order to ensure
that the IRQ handler still works in the BROM FEL code after getting
control back from the SPL. This is done in the sunxi code instead of
abusing ifdefs in 'start.S'.
The decision whether to load the main u-boot binary from the SD card or
return to the FEL code in the BROM is done at runtime.

The link register value can be required on some boards (e.g. FEL mode on
sunxi) so use a branch instruction to jump to save_boot_params() instead
of a branch link.
This requires a branch back to save_boot_params_ret so adjust the users
to deal with this. For exynos just drop the function since it doesn't
do anything.

Do not use CONFIG_SYS_MEM_TOP_HIDE for the framebuffer, instead override
board_get_usable_ram_top to make sure that u-boot is not relocated into the
area where we want to use the framebuffer, and patch the devicetree from
sunxi_simplefb_setup() to tell the kernel to not touch the framebuffer.
This makes u-boot properly see the framebuffer as dram, and initalize the
level 2 cache for it, fixing the very slow cfb scrolling problem.
As an added bonus this stops us from reserving the framebuffer when simplefb
is not used because an older kernel is booted, or hdp is used and no hdmi
cable was plugged in, freeing up the memory for kernel use in these cases.

Commit a93648d197 introduced linker generated
lists for imagetool which is the base for some host tools (mkimage, dumpimage,
et al.). Unfortunately some host tool chains do not support the used type of
linker scripts. Therefore this commit broke these host-tools for them, namely
FreeBSD and Darwin (OS/X).
This commit tries to fix this. In order to have a clean distinction between host
and embedded code space we need to introduce our own linker generated list
instead of re-using the available linker_lists.h provided functionality. So we
copy the implementation used in linux kernel script/mod/file2alias.c which has
the very same problem (cause it is a host tool). This code also comes with an
abstraction for Mach-O binary format used in Darwin systems.
