Detailed Description

SRAM representation of the OTP ROT_CREATOR_AUTH_CODESIGN partition.

The data is loaded into SRAM via sigverify_otp_keys_init() and its integrity is verified by sigverify_otp_keys_check() before use.

Static assertions are used inside the implementation to ensure that the size of the data structure matches the size of the OTP partition.
