commit d9f43c8f sets
get_reset_cause() as static, but this conflicts with mx5
where its prototype is in sys_proto.h.

Drop it from sys_proto.h and drop print_cpuinfo from mx53_loco,
factorizing the call for this board.

Currently in some cases SDRAM init requires global_data to be available
and soon this will not be available prior to board_init_f().  Adjust the
code paths in these cases to be correct.  In some cases we had the SPL
stack be in DDR as we might have large stacks (due to Falcon Mode +
Environment).  In these cases switch to CONFIG_SPL_STACK_R.  In other
cases we had simply been setting CONFIG_SPL_STACK into SRAM.  In these
cases we no longer need to (CONFIG_SYS_INIT_SP_ADDR is used and is also
in SRAM) so drop those lines.

When CONFIG_SYS_MALLOC_SIMPLE is defined, free() is a static inline. Make
sure that the export interface still builds in this case.
Signed-off-by: NSimon Glass <sjg@chromium.org>

At present SPL uses a single stack, either CONFIG_SPL_STACK or
CONFIG_SYS_INIT_SP_ADDR. Since some SPL features (such as MMC and
environment) require a lot of stack, some boards set CONFIG_SPL_STACK to
point into SDRAM. They then set up SDRAM very early, before board_init_f(),
so that the larger stack can be used.

This is an abuse of lowlevel_init(). That function should only be used for
essential start-up code which cannot be delayed. An example of a valid use is
when only part of the SPL code is visible/executable, and the SoC must be set
up so that board_init_f() can be reached. It should not be used for SDRAM
init, console init, etc.

Add a CONFIG_SPL_STACK_R option, which allows the stack to be moved to a new
address before board_init_r() is called in SPL.

The expected SPL flow (for CONFIG_SPL_FRAMEWORK) is documented in the README.

This is already set up in crt0.S. We don't need a new structure and don't
really want one in the 'data' section of the image, since it will be empty
and crt0.S's changes will be ignored.

As an interim measure, remove it only if CONFIG_DM is not defined. This
allows us to press ahead with driver model in SPL and allow the stragglers
to catch up.

This function has grown into something of a monster. Some boards are setting
up a console and DRAM here in SPL. This requires global_data which should be
set up in one place (crt0.S).

There is no need for SPL to use s_init() for anything since board_init_f()
is called immediately afterwards.

Since more than one board requires memory reservation
for the secure firmware, the reservation code can be
made in a common code.
Now, to reserve some part of the the last bank,
board config should define:
- CONFIG_TZSW_RESERVED_DRAM - len in bytes
- CONFIG_NR_DRAM_BANKS - number of memory banks
