GetConfig

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

ConfigItem	Name
1	DisableProgramVerification
2	MemoryConfiguration
5	HardwareType (0=Icosa, 1=Copper)
6	IsRetail
7	IsRecoveryBoot
8	DeviceId (byte7 clear).
9	BootReason
10	MemoryArrange
11	AllowSkippingNrrSignatures
13	BatteryProfile?

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.

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

Same input gives same output. Output changes when system is rebooted.

Takes two input words, a ConfigItem and the value to set.

ConfigItem	Name
13	Battery profile?

No input params.

Uses #GetConfig internally with id=6. Returns true if output from that is 0, or if the SMC returned error 2.

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

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