AW: HAB/SecureBoot on IMX8MN

[Rouven Czerwinski]

Hi Bernd,

One of the pitfalls we had when enabling HAB for i.MX8MQ was that the
SIP supported by the downstream TF-A to request the HAB event log was
stalling the SoC forever. I couldn't find a way to make this work, so
instead for i.MX8MQ we are parsing the HAB event log directly from
SRAM. The i.MX8MN address is probably different and you'll have to
check whether the same restrictions apply, i.e. if the HAB SIP is still
broken on i.MX8MN.

Best regards,
Rouven
