g) Freescale SOC SEC Security Engines
Required properties:
- device_type : Should be "crypto"
- model : Model of the device. Should be "SEC1" or "SEC2"
- compatible : Should be "talitos"
- reg : Offset and length of the register set for the device
- interrupts : <a b> where a is the interrupt number and b is a
field that represents an encoding of the sense and level
information for the interrupt. This should be encoded based on
the information in section 2) depending on the type of interrupt
controller you have.
- interrupt-parent : the phandle for the interrupt controller that
services interrupts for this device.
- num-channels : An integer representing the number of channels
available.
- channel-fifo-len : An integer representing the number of
descriptor pointers each channel fetch fifo can hold.
- exec-units-mask : The bitmask representing what execution units
(EUs) are available. It's a single 32 bit cell. EU information
should be encoded following the SEC's Descriptor Header Dword
EU_SEL0 field documentation, i.e. as follows:
bit 0 = reserved - should be 0
bit 1 = set if SEC has the ARC4 EU (AFEU)
bit 2 = set if SEC has the DES/3DES EU (DEU)
bit 3 = set if SEC has the message digest EU (MDEU)
bit 4 = set if SEC has the random number generator EU (RNG)
bit 5 = set if SEC has the public key EU (PKEU)
bit 6 = set if SEC has the AES EU (AESU)
bit 7 = set if SEC has the Kasumi EU (KEU)
bits 8 through 31 are reserved for future SEC EUs.
- descriptor-types-mask : The bitmask representing what descriptors
are available. It's a single 32 bit cell. Descriptor type
information should be encoded following the SEC's Descriptor
Header Dword DESC_TYPE field documentation, i.e. as follows:
bit 0 = set if SEC supports the aesu_ctr_nonsnoop desc. type
bit 1 = set if SEC supports the ipsec_esp descriptor type
bit 2 = set if SEC supports the common_nonsnoop desc. type
bit 3 = set if SEC supports the 802.11i AES ccmp desc. type
bit 4 = set if SEC supports the hmac_snoop_no_afeu desc. type
bit 5 = set if SEC supports the srtp descriptor type
bit 6 = set if SEC supports the non_hmac_snoop_no_afeu desc.type
bit 7 = set if SEC supports the pkeu_assemble descriptor type
bit 8 = set if SEC supports the aesu_key_expand_output desc.type
bit 9 = set if SEC supports the pkeu_ptmul descriptor type
bit 10 = set if SEC supports the common_nonsnoop_afeu desc. type
bit 11 = set if SEC supports the pkeu_ptadd_dbl descriptor type
..and so on and so forth.
Example:
/* MPC8548E */
crypto@30000 {
device_type = "crypto";
model = "SEC2";
compatible = "talitos";
reg = <30000 10000>;
interrupts = <1d 3>;
interrupt-parent = <40000>;
num-channels = <4>;
channel-fifo-len = <24>;
exec-units-mask = <000000fe>;
descriptor-types-mask = <073f1127>;
};
More devices will be defined as this spec matures.

Select this option to enable more accurate task and CPU time
accounting. This is done by reading a CPU counter on each
kernel entry and exit and on transitions within the kernel
between system, softirq and hardirq state, so there is a
small performance impact. This also enables accounting of
stolen time on logically-partitioned systems running on
IBM POWER5-based machines.
