This Trusted Application allows enabling SCP03 as well as provisioning
the keys on TEE controlled secure element (ie, NXP SE050).
All the information flowing on buses (ie I2C) between the processor
and the secure element must be encrypted. Secure elements are
pre-provisioned with a set of keys known to the user so that the
secure channel protocol (encryption) can be enforced on the first
boot. This situation is however unsafe since the keys are publically
available.
For example, in the case of the NXP SE050, these keys would be
available in the OP-TEE source tree [2] and of course in the
documentation corresponding to the part.
To address that, users are required to rotate/provision those keys
(ie, generate new keys and write them in the secure element's
persistent memory).
For information on SCP03, check the Global Platform HomePage and
google for that term [1]

When multiple log() calls are used which don't end in newline, the
log prefix is prepended multiple times in the same line. This makes the
output look strange.
Fix this by detecting when the previous log record did not end in newline.
In that case, setting a flag.
Drop the unused BUFFSIZE in the test while we are here.
As an example implementation, update log_console to check the flag and
produce the expected output.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present only a single flag (force_debug) is used in log records. Before
adding more, convert this into a bitfield, so more can be added without
using more space.
To avoid expanding the log_record struct itself (which some drivers may
wish to store in memory) reduce the line-number field to 16 bits. This
provides for up to 64K lines which should be enough for anyone.

As an example of an SPL test, add a new test for loading a FIT within
SPL. This runs on sandbox_spl. For this to work, the text base is adjusted
so that there is plenty of space available.
While we are here, document struct spl_load_info properly, since this is
currently ambiguous.
This test only verifies the logic path. It does not actually check that
the image is loaded correctly. It is not possible for sandbox's SPL to
actually run u-boot.img since it currently includes u-boot.bin rather than
u-boot. Further work could expand the test in that direction.
The need for this was noted at:

At present this casts addresses to pointers so cannot work with sandbox.
Update the code to use map_sysmem() instead.
As part of this change, the existing load_ptr is renamed to src_ptr since
it is not a pointer to load_addr. It is confusing to use a similar name
for something that is not actually related. For the alignment code,
ALIGN() is used instead of open-coded alignment. Add a comment to the line
that casts away a const.

With of-platdata we always have a dtv struct that holds the platform data
provided by the driver_info record. However, this struct can be empty if
there are no actual devicetree properties provided.
The upshot of empty platform data is that it will end up as a zero-size
member in the BSS section, which is fine. But if the driver specifies
plat_auto then it expects the correct amount of space to be allocated.
At present this does not happen, since device_bind() assumes that the
platform-data size will always be >0. As a result we end up not
allocating the space and just use the BSS region, overwriting whatever
other contents are present.
Fix this by removing the condition that platform data be non-empty, always
allocating space if requested.
This fixes a strange bug that has been lurking since of-platdata was
implemented. It has likely never been noticed since devices normally have
at least some devicetree properties, BSS is seldom used on SPL, the dtv
structs are normally at the end of bss and the overwriting only happens
if a driver changes its platform data.
It was discovered using sandbox_spl, which exercises more features than
a normal board might, and the critical global_data variable 'gd' happened
to be at the end of BSS.
