David Brown 5f4e1484b7 sim: mcuboot-sys: Avoid duplicate C files
When building mcuboot-sys, the build script currently adds some
duplicate files.  When used as a library, this works, because the code
is linked in as a library.  However, when mcuboot-sys is tested itself,
all specified files will be brought in, which results in duplicate
symbols for these files.

Fix this by keeping track of all of the files that we've added, and
making sure to add each file once.  Additionally, instead of using the
orphaned files in mbedtls-asn1, just always use the verions in the main
mbedtls library.  There are some configurations of the code that end up
using both the extracted files and the full mbed TLS.  Avoid that
conflict by just always using the full tree.

When collected together as a workspace, the test framework ends up

David Brown f17d39112f sim: Test ram-loading with DIRECT_XIP
Combine all of the pieces to be able to test ram loading with multiple
images.  We construct a model `RamData` that indicates where each image
should be loaded into RAM.  This has to be made early enough to compute
signatures on the images, and then used later to verify that the images
were loaded properly.

David Brown 8a4e23bb6b sim: Basic ram-load test
Test the basic configuration for ram loading.  Instead of a fixed
address for RAM, the values come dynamically from a thread-local
variable (allowing the tests to run in parallel).  The size of the ram
along with the address of the buffer in the test address space are
passed in this way.

This tests the single-image configurations of ram loading.  Testing
multi-image will take additional work, as the RAM will need to be large
enough for both images, and the second image will need a meaningful
offset address in RAM.

Allow the sim to test configurations with MCUBOOT_RAM_LOAD defined.
This does not define any tests for this mode.

This adds definitions for simulated RAM offsets to the simulator.  This

RAM will be located.  For now, just give these somewhat reasonable
values so that we are able to at least compile the RAM_LOADING code in

David Brown 641af4530c boot: Support Mbed TLS ECDSA for signatures
Add Mbed TLS ECDSA signature verification as an option (in addition to
Tinycrypt and the CC310 hardware version).  Although the Mbed TLS ECDSA
verification code is both larger and slower, this will still save space
if there is another reason that the Mbed TLS code is already being
brought in for another reason (such as certificate management, for
example).

Mbed TLS's ECDSA verification works at a different level than the other
two libraries, so this takes a bit of reworking.  There are some
additional parameters passed to the various functions, and a new define
MCUBOOT_ECDSA_NEED_ASN1_SIG to indicate that the ecdsa verification
wants the original ASN1 signature, not a decoded key.

This adds the boot changes and simulator support to test this configuration.

Andrzej Puzdrowski f573b392ec bootutil: extracted app common library from bootutil_misc
Part of code of boot/bootutil/ is re-implemented in zephyr-rtos
repository.
As some code are defined here and there it becomes problem when
need to include it with outstanding feature in a build.
It is possible to mitigate problem using #fdefry - but this was
rather temporary hack.

This patch introduce new module which is common for MCUBoot build
and application build.
Common code were extracted to bootutil_public.c source file and
bootutil_public.h header

MCUboot also select DISABLE_MCUBOOT_BOOTUTIL_LIB_OWN_LOG Kconfig
option, as it must define log configuration on its own for all its
sourcecode.

Fabio Utzig 4b2e55f362 boot: bootutil: drop flash_area_read_is_empty
Removes the current `flash_area_read_is_empty` which lacked a bit of
clarity in its naming and error handling, as well as requiring an
extra API in the flash map, and switches to using an internal function
`bootutil_buffer_is_erased`.

Code that was previously using `flash_area_read_is_empty` must now be
updated to do a `flash_area_read` followed by a call to
`bootutil_buffer_is_erased` with the read buffer.

The proposal was previously discussed here:

Blaž Hrastnik 4f4833d465 Abstracting mcuboot crypto functions for cleaner porting and less of an ifdef hell.
- The enc_context needs to initialize.

boot_enc_load seems to always be used to start the process, so calling
init inside makes sense.

- Handle boot_encrypt getting called with size of 0.

- No need to free contexts because Zephyr sets MBEDTLS_PLATFORM_NO_STD_FUNCTIONS.

I don't quite like this because it's implicit and will leak memory on
