About FIQ interrupt on AM335x

Ryutaro Yoshida

Hello,
I have refered the interrupt section(Chapter 6) of AM335x TRM.

There is a description here:
NOTE: FIQ is not available on general-purpose (GP) devices.

Which one is correct as this meaning?
   a) FIQ is not available on some interrupt sources on AM335x.
   b) FIQ is not completely available on AM335x.
   c) other

Hi RY,

The note is absolutely correct. FIQ is available only on high-security (HS) devices.

Are you saying that there are/will be AM335x high-security devices available?

Regards,
