19c402afa2 image: Add RSA support for image signing
RSA provides a public key encryption facility which is ideal for image
signing and verification.

Images are signed using a private key by mkimage. Then at run-time, the
images are verified using a private key.

This implementation uses openssl for the host part (mkimage). To avoid
bringing large libraries into the U-Boot binary, the RSA public key
is encoded using a simple numeric representation in the device tree.

56518e7104 image: Support signing of images
Add support for signing images using a new signature node. The process
is handled by fdt_add_verification_data() which now takes parameters to
provide the keys and related information.

ca35a0cdf2 exynos: Avoid function instrumentation for microsecond timer
For tracing to work it has to be able to access the microsecond timer
without causing a recursive call to the function entry/exit handlers.
Add attributes to the relevant functions to support this.

bce1b92aa1 arm: Implement the 'fake' go command
Implement this feature on ARM for tracing.

It would be nice to have generic bootm support so that it is easily
implemented on any arch.

d0ae31eb07 Add a 'fake' go command to the bootm command
For tracing it is useful to run as much of U-Boot as possible so as to get
a complete picture. Quite a bit of work happens in bootm, and we don't want
to have to stop tracing before bootm starts.

Add a way of doing a 'fake' boot of the OS - which does everything up to
the point where U-Boot is about to jump to the OS image. This allows
tracing to record right until the end.

This requires arch support to work.

35fc84fa1f Refactor the bootm command to reduce code duplication
At present the bootm code is mostly duplicated for the plain 'bootm'
command and its sub-command variant. This makes the code harder to
maintain and means that changes must be made to several places.

Introduce do_bootm_states() which performs selected portions of the bootm
work, so that both plain 'bootm' and 'bootm <sub_command>' can use the
same code.

Additional duplication exists in bootz, so tidy that up as well. This
is not intended to change behaviour, apart from minor fixes where the
previously-duplicated code missed some chunks of code.

983c72f479 Clarify bootm OS arguments
At present the arguments to bootm are processed in a somewhat confusing
way. Sub-functions must know how many arguments their calling functions
have processed, and the OS boot function must also have this information.
Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
the same way.

Adjust the code so that arguments are removed from the list before calling
a sub-function. This means that all functions can know that argv[0] is the
first argument of which they need to take notice.

e2ee100fd8 sandbox: Support trace feature
Support tracing on sandbox by adding suitable CONFIG options. To enable it,
compile U-Boot with FTRACE=1.

The timer functions are marked to skip tracing, since these are called from
