GetConfig
Takes an input word (ConfigItem), and returns a u64 with the config params.
| ConfigItem | Name |
|---|---|
| 5 | HardwareType (0=Icosa, 1=Copper) |
| 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. Output changes when system is rebooted.
ScrambleKeyB
Behaves similar to #ScrambleKeyA, but with different output.
Also console unique. This is not the inverse operation of #ScrambleKeyA.
SetConfig
Takes two input words, a ConfigItem and the value to set.
| ConfigItem | Name |
|---|---|
| 13 | Unknown. |
GetDevunitFlag
No input params.
Returns an u8 flag for whether the system is devunit. Output flag is 0 on retail.
EncDec0
Last SPL cmd used by SSL-sysmodule for TLS client-privk.
