Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Move ARM- and ARM64-accelerated menus into a submenu under
the Crypto API menu (paralleling all the architectures).

Make each submenu always appear if the corresponding architecture
is supported. Get rid of the ARM_CRYPTO and ARM64_CRYPTO symbols.

The "ARM Accelerated" or "ARM64 Accelerated" entry disappears from:
General setup --->
Platform selection --->
Kernel Features --->
Boot options --->
Power management options --->
CPU Power Management --->
[*] ACPI (Advanced Configuration and Power Interface) Support --->
[*] Virtualization --->
[*] ARM Accelerated Cryptographic Algorithms --->
(or)
[*] ARM64 Accelerated Cryptographic Algorithms --->
...
-*- Cryptographic API --->
Library routines --->
Kernel hacking --->

and moves into the Cryptographic API menu, which now contains:
...
Accelerated Cryptographic Algorithms for CPU (arm) --->
(or)
Accelerated Cryptographic Algorithms for CPU (arm64) --->
[*] Hardware crypto devices --->
...
