Seppo Takalo fc9e75bddc Allow Devicekey::generate_root_of_trust() to define key size. 
By default, generate 16 byte keys, to be compatible with bootloader.
But allow user to generate 32 byte keys as well.

Add check for return code in DeviceKey to avoid injecting invalid ROT

Kimmo Vaisanen 29affbccab Remove explicit include of mbedtls/config.h 
Including mbedtls/config.h should not be done explicitely. This prevents using MBEDTLS_CONFIG_FILE macro.
Correct config file is automatically included by other mbedtls header files.

Tymoteusz Bloch 0e7a53cdb1 DeviceKey Root of Trust generation refactored. 
It's no longer automatically and silently created.

Seppo Takalo f0790cd7b2 Remove usage of Mbed TLS internal function from DeviceKey. 
DeviceKey was using mbedtls_ssl_safer_memcmp() to compare result against
buffer of equal length, but zero content. This comparison makes no sense
as the entropy function is already returning proper error, if it fails.

Chun-Chieh Li 1bb351f410 DeviceKey: Fix random key doesn't generate on MBEDTLS_ENTROPY_HARDWARE_ALT 
Originally, when DEVICE_TRNG is defined, MBEDTLS_ENTROPY_HARDWARE_ALT will also be defined
accordingly to provide entropy source. This is fine for targets supporting TRNG. However, for
targets without TRNG, it is also possible to provide non-TRNG entropy source solution via the
define MBEDTLS_ENTROPY_HARDWARE_ALT. Related discussion can be found at:

Ron Eldor c94b5861e4 Add mbedtls platform setup and teardown to modules 
Add calls to `mbedtls_platform_setup()`
and `mbedtls_platform_teardown()` to all modules and tests using Mbed TLS.

Yossi Levy 2adf5db881 Adding a test if device key buffer has changed after calling to entropy func. this should enable as to eliminate some rare cases when the trng fail but still return success. 2019-01-10 10:18:44 +02:00

Alastair D'Silva 2617c5d55b Don't use define checks on DEVICE_FOO macros (mbed code) 
The DEVICE_FOO macros are always defined (either 0 or 1).

This patch replaces any instances of a define check on a DEVICE_FOO
macro with value test instead.
