For now, just some random data gathered from initial tracing of the SEP, should be updated as i start digging deeper

Endpoint numbers: 0x12 - SKS (SEP Key Store/Secure Key Store) 0xFF - Boot255 - seems to be used to signal to SEP of some shared memory region? 0xFE - Boot254 - related to IMG4 auth

unknown: endpoint for biometric auth/SBIO

Notes:

SKS is very spammy as mailbox messages to/from sep are constantly being sent
