5b123e0109 lib: rsa: add support to other openssl engine types than pkcs11
There are multiple other openssl engines used by HSMs that can be used to
sign FIT images instead of forcing users to use pkcs11 type of service.

Relax engine selection so that other openssl engines can be specified and
use generic key id definition formula.

b225c92fd0 efi_loader: Change return type of efi_add_memory_map()
We currently have some inconsistent use of efi_add_memory_map()
throughout the code. In particular the return value of efi_add_memory_map()
is not interpreted the same way by various users in the codebase.

This patch does the following:

- Changes efi_add_memory_map() to return efi_status_t.
- Adds a method description to efi_add_memory_map().
- Changes efi_add_memory_map() to return EFI_SUCCESS
- Returns non-zero for error in efi_add_memory_map()
- Updates efi_allocate_pages() to new efi_add_memory_map()
- Updates efi_free_pages() to new efi_add_memory_map()
- Updates efi_carve_out_dt_rsv() to new efi_add_memory_map()
- Updates efi_add_runtime_mmio()  to new efi_add_memory_map()

2a51e16bd5 configs: Make USE_TINY_PRINTF depend on SPL||TPL and be default
The USE_TINY_PRINTF symbol only changes things within SPL and TPL
builds, so make it depend on that support.  Next, make it default as
within these cases we should rarely have need of more advanced print
formats outside of the debug context.

To do this, in a few cases we need to correct our Kconfig dependencies
as we had cases of non-SPL targets select'ing this symbol.  Finally, in
the case of a few boards we really do need the full printf
functionality.

f2980ece06 sandbox: Quit when hang() is called
It doesn't make a lot of sense to hang on sandbox when hang() is called,
since the only way out is Ctrl-C. In fact, Ctrl-C does not work if the
terminal is in raw mode, which it will be if the command-line has not been
reached yet. In that case, Ctrl-Z / kill -9 must be used, which is not
very friendly.

Avoid all of this by quiting when hang() is called.
