For the RK3368, we want to use OF_PLATDATA in TPL, but full OF_CONTROL
in SPL: this requires the introduction of a new family of
configuration options to decouple SPL_OF_CONTROL and SPL_OF_PLATDATA
from TPL.

Consequently, Makefile.spl needs to be adjusted to test for these
configuration items through the $(SPL_TPL_) macro instead of
hard-coding the SPL variant.

This adds support for a TPL-variant of SYS_MALLOC_F_LEN:

The back-to-bootrom option is rather unfortunately named

To make is selectable through CONFIG_IS_ENABLED(ROCKCHIP_BACK_TO_BOOTROM),
we need to rename it.  At the same time, we introduce a TPL_ variant of

This change is motivated by our RK3368 boot process, which returns to

include/configs/rock.h: undef

The back-to-bootrom support for Rockchip is equivalent to an
(assembly) implementation of setjmp/longjmp (i.e. it saves the
stack-pointer, link-register and callee-saved registers). Up until
now, this had only been implemented for AArch32 (i.e. ARMv7 or older),
which puts the new ARMv8 devices (which boot in AArch64 mode) at a
slight disadvantage.

To allow use of the 'back-to-bootrom' feature on new devices (e.g. the
RK3368), this commit adds an implementation for AArch64.

On the RK3368, we want our TPL to use the 'return to bootrom' boot
method (to have the bootrom load up the SPL stage) and then continue
with different boot methods (MMC, SPI, etc.) from SPL.

This adds the config option needed to control the availabily of the
'return to bootrom' boot-method separately for the TPL stage.

Some devices (e.g. the RK3368) have only limited SRAM, but provide

For target systems like these, we add a boot device BOOTROM that will
invoke a board-specific hook to return to the bootrom (if supported).
