This PR provides a porting layer implementation and framework for building an mcuboot-based bootloader with Mbed-OS. Some symbols are not provided by the Mbed-OS port within mcuboot, namely:
- The secondary storage device (see below)
- The signing keys
- The encryption keys, if used
Use of this port is demonstrated by the following projects:
- https://github.com/AGlass0fMilk/mbed-mcuboot-demo (a complete mcuboot/Mbed-OS-based bootloader)
- https://github.com/AGlass0fMilk/mbed-mcuboot-blinky (example showing how to make an Mbed-OS application that is bootable by mcuboot)
Memory porting implementation:
The underlying implemenation uses Mbed's BlockDevice API as the storage backend for mcuboot's memory operations. This provides a very flexible way of configuring the location and layout of the secondary flash storage area. To build an mcuboot-based bootloader with Mbed-OS, the user must implement a hook function, mbed::BlockDevice* get_secondary_bd(), to provide the secondary BlockDevice that mcuboot will use.
The signing and encryption keys must also be provided by the user. They can be generated using the existing imgtool utility in the same manner used by Zephyr. There are no automated build steps currently provided by Mbed-OS to sign/encrypt build artifacts.
Known limitations:
The update candidate encryption features have not yet been fully tested. A truly secure implementation will require integration with Mbed's TRNG API in the future to inhibit side-channel attacks on the decryption process.
The TinyCrypt backend is currently only supported for Mbed-OS builds when building with the GCC toolchain. The new cmake-based Mbed-OS build system will fix the underlying issue (file name uniqueness).

Start with some documentation on ECDSA signatures, and the problems with
the current padding approach. Present a plan to support correctly
formatted ECDSA signatures, and how to handle the transition both in the
C code, as well as the tooling that signs images.

This will fix#336 by adding deprecation warning to Jira and
Confluence links as these are not used by the project anymore.

Github pages assumes that links to files using relative
names point to the same location so this should work both
when accessing through the github browser and mcuboot.com

The complex blocks are just verbatim, and some of the outline-style

them.

Github pages allows the documentation to be in the master branch in a
'docs' directory to be rendered as the main site (mcuboot.com). Rename
this directory, and pull in the documentation files from the old
gh-pages branch.
The main index.md page does not link to the rest of the docs yet, and
that change can be made in a future patch.
