GetConfig

Takes an input word (ConfigItem), and returns a u64 with the config params.

ConfigItem Name
5 HardwareType
8 64bit DeviceId with byte7 clear.
11 Allow skipping RSA signatures on NRR.

Output from this when used by NIM must match the set:cal DeviceId with byte7 cleared, otherwise NIM will panic.

RO checks id11, if set then skipping NRR rsa signatures is allowed.

ScrambleKeyA

Takes 16-bytes as input and two u32s. Outputs random-looking 16-bytes.

Same input gives same output. Console unique.

ScrambleKeyB

Behaves similar to #ScrambleKeyA, but with different output.

Also console unique. This is not the inverse operation of #ScrambleKeyA.

GetDevunitFlag

No input params.

Returns an u8 flag for whether the system is devunit. Output flag is 0 on retail.

Cmd13

Last SPL cmd used by SSL-sysmodule for TLS client-privk.
