mkimage: Support adding device tree files to a FIT
To make the auto-FIT feature useful we need to be able to provide a list of

This is not required for creating legacy images.
Often the FIT is pretty standard, consisting of an OS image, some device
tree files and a single configuration. We can handle this case automatically
and avoid needing a .its file at all.
To start with, support automatically generate the FIT using a new '-f auto'
option. Initially this only supports adding a single image (e.g. a linux
kernel) and a single configuration.

sf: Correct data types in stm_is_locked_sr()
The stm_is_locked_sr() function is picked from Linux kernel. For reason
unknown, the 64bit data types used by the function and present in Linux

The testcase performed was done using ST M25P80 chip.
The command used was:
=> sf protect unlock 0 0x10000
The call chain starts in stm_unlock(), which calls stm_is_locked_sr()
with negative ofs argument. This works fine in Linux, where the "ofs"
is loff_t, which is signed long long, while this fails in U-Boot, where
"ofs" is u32 (unsigned int). Because of this signedness problem, the
expression past the return statement to be incorrectly evaluated to 1,

The correction is very simple, just use the correctly sized data types
with correct signedness in the function to make it work as intended.

malloc: use hidden visibility
When running sandbox, the following phases occur, each with different
malloc implementations or behaviors:
1) Dynamic linker execution, using the dynamic linker's own malloc()
implementation. This is fully functional.
2) After U-Boot's malloc symbol has been hooked into the GOT, but before
any U-Boot code has run. This phase is entirely non-functional, since
U-Boot's gd symbol is NULL and U-Boot's initf_malloc() and
mem_malloc_init() have not been called.
At least on Ubuntu Xenial, the dynamic linker does make both malloc() and
free() calls during this phase. Currently these free() calls crash since
they dereference gd, which is NULL.
U-Boot itself makes no use of malloc() during this phase.
3) U-Boot execution after gd is set and initf_malloc() has been called.
This is fully functional, albeit via a very simple malloc()
implementation.
4) U-Boot execution after mem_malloc_init() has been called. This is fully
functional with a complete malloc() implementation.
Furthermore, if code that called malloc() during phase 1 calls free() in
phase 3 or later, it is likely that heap corruption will occur, since
U-Boot's malloc implementation will assume the pointer is part of its own
heap, although it isn't. I have not actively observed this happening.
To prevent phase 2 from happening, this patch makes all of U-Boot's malloc
library public symbols have hidden visibility. This prevents them from
being hooked into the GOT, so only code in the U-Boot binary itself
actually calls them; any other code will call into the standard C library
malloc(). This also avoids the "furthermore" issue mentioned above.
I have seen references to this GCC pragma in blog posts from 2008, and
RHEL5's ancient gcc appears to accept it fine, so I believe it's quite
safe to use it without checking gcc version.

Bad case scenario:
[1] The hardware block is already running before pinctrl is handled.
(the reset is de-asserted by default or by a firmware, for example)
[2] The pin-muxing is set up. The input signals to hardware block
are pulled-down by the chip-internal biasing.
[3] The pins are input-enabled. The signals from the board reach the
hardware block.
Actually, one invalid character is input to the UART blocks for such
SoCs as PH1-LD4, PH1-sLD8, where UART devices start to run at the
power on reset.
To avoid such problems, pins should be input-enabled before muxing.
For the case where an external VBUS is used, we should enable the external
VBUS comparator in the driver. This would prevent an unnecessary overcurrent
error which would then disable the host port.
