Detailed Description

Secure debug control.

Parameters

subhdr	Magic and size for integrity check
allow_jtag_unlock	Flag controlling runtime jtag unlock feature. Set to 0x5A to enable jtag unlock with a signed certificate.
allow_wildcard_unlock	Flag controlling whether a device unique certificate is required for jtag unlock. Set to 0x5A to remove the device uniqueness restriction on the certificate.
allowed_debug_level_rsvd	Reserved field to control the allowed debug level in future. Set to 0 currently.
rsvd	reserved for future use.
min_cert_rev	Minimum SWREV value that must be present in the jtag unlock certificate. Set to 0 to skip check
jtag_unlock_hosts	array of host ids that are allowed to unlock jtag with a signed certificate at runtime. Set host id to 0 if unused. Set host id to 128 if any host can unlock JTAG via the API.
