So far spl-boards have declared the back_to_brom() function as simple
extern in the files themself. That doesn't scale well if every boards
defines this on its own.
Therefore move the declarations to a bootrom header.

Right now the ROCKCHIP_SPL_BACK_TO_BROM option both triggers
compilation of the bootrom hook-code as well as enabling the
behaviour of loading the full U-Boot via the boot.
New added socs may always need the bootrom code, while still
being able to decide between loading U-Boot regularly or via
the bootrom separately.
So move the compilation of the bootrom code to a hidden option
that gets selected by ROCKCHIP_SPL_BACK_TO_BROM, but can also
be selected by other parts.

Right now the u-boot,dm-pre-reloc flag will make each marked node
always appear in both spl and tpl. But systems needing an additional
tpl might have special constraints for each, like the spl needing to
be very tiny.
So introduce two additional flags to mark nodes for only spl or tpl
environments and introduce a function dm_fdt_pre_reloc to automate
the necessary checks in code instances checking for pre-relocation
flags.
The behaviour of the original flag stays untouched and still marks
a node for both spl and tpl.

At present malloc_base/_limit/_ptr are not initialised in spl_init() when
we call spl_init() in board_init_f(). This is due to a recent change aimed
at avoiding overwriting the malloc area set up on some boards by
spl_relocate_stack_gd().
However if CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN is not defined, we now
skip setting up the memory area in spl_init() which is obviously wrong.
To fix this, add a new function spl_early_init() which can be called in
board_init_f().

At first, the ARM64 Linux booting requirement recommended that the
kernel image be placed text_offset bytes from 2MB aligned base near
the start of usable system RAM because memory below that base address
was unusable at that time.
This requirement was relaxed by Linux commit a7f8de168ace ("arm64:
allow kernel Image to be loaded anywhere in physical memory").
Since then, the bit 3 of the flags field indicates the tolerance
of the kernel physical placement. If this bit is set, the 2MB
aligned base may be anywhere in physical memory. For details, see
Documentation/arm64/booting.txt of Linux.
The booti command should be also relaxed. If the bit 3 is set,
images->ep is respected, and the image is placed at the nearest
bootable location. Otherwise, it is relocated to the start of the
system RAM to keep the original behavior.
Another wrinkle we need to take care of is the unknown endianness of
text_offset for a kernel older than commit a2c1d73b94ed (i.e. v3.16).
We can detect this based on the image_size field. If the field is
zero, just use a fixed offset 0x80000.

Richard reported U-Boot tools issues in OpenEmbedded/Yocto project.
OE needs to be able to change the default compiler. If we pass in
HOSTCC through the make command, it overwrites all HOSTCC instances,
including ones in tools/Makefile and tools/env/Makefile, which breaks
"make cross_tools" and "make env", respectively.
Add "override" directives to avoid overriding HOSTCC instances that
really need to point to the cross-compiler.
