This patch adds a sec_init call into arch_misc_init(). Doing so in
conjunction with the patch "drivers/crypto/fsl: assign job-rings to
non-TrustZone" enables use of the CAAM in Linux when OPTEE/TrustZone is
active.
u-boot will initialise the RNG and assign ownership of the job-ring
registers to a non-TrustZone context. With recent changes by Lukas Auer to
fully initialize the RNG in sec_init() this means that u-boot will hand-off
the CAAM in a state that Linux then can use the CAAM without touching the
reserved DECO registers.
This change is safe both for the OPTEE/TrustZone boot path and the regular
non-OPTEE/TrustZone boot path.

After enabling TrustZone various parts of the CAAM silicon become
inaccessible to non TrustZone contexts. The job-ring registers are designed
to allow non TrustZone contexts like Linux to still submit jobs to CAAM
even after TrustZone has been enabled.
The default job-ring permissions after the BootROM look like this for
job-ring zero.
ms=0x00008001 ls=0x00008001
The MS field is JRaMIDR_MS (job ring MID most significant).
Referring to "Security Reference Manual for i.MX 7Dual and 7Solo
Applications Processors, Rev. 0, 03/2017" section 8.10.4 we see that
JROWN_NS controls whether or not a job-ring is accessible from non
TrustZone.
Bit 15 (TrustZone) is the logical inverse of bit 3 hence the above value of
0x8001 shows that JROWN_NS=0 and TrustZone=1.
Clearly then as soon as TrustZone becomes active the job-ring registers are
no longer accessible from Linux, which is not what we want.
This patch explicitly sets all job-ring registers to JROWN_NS=1 (non
TrustZone) by default and to the Non-Secure MID 001. Both settings are
required to successfully assign a job-ring to non-secure mode. If a piece
of TrustZone firmware requires ownership of job-ring registers it can unset
the JROWN_NS bit itself.
This patch in conjunction with a modification of the Linux kernel to skip
HWRNG initialisation makes CAAM usable to Linux with TrustZone enabled.

SION bit should be used in the situation that we need
to read back the value of a pin and should not be set by
default macro.
We get some malfunction as raised by following thread
https://www.spinics.net/lists/linux-usb/msg162574.html
As reported by this application note:
https://www.nxp.com/docs/en/application-note/AN5078.pdf
The software input on (SION) bit is an option to force an input
path to be active regardless of the value driven by the
corresponding module. It is used when the nature direction
of a pin depending on selected alternative function is an output,
but it is needed to read the real logic value on a pin.
The SION bit can be used in:
• Loopback: the module of a selected alternative function drives
the pad and also receives the pad value as an input
• GPIO capture: the module of a selected alternative function
drives the pin and the value is captured by the GPIO
SION bit is not necessary when the pin is configured as a peripheral
apart specific silicon bug. If an application needs to have this
set, this should be done in board file or in dts file

The mapping from the driver's index to the environment variable's name

assumed that eth_devices for the controllers on the board are always
indexed in the same order.
The environment variables are removed after programming the hardware
because the variables seem to influence MAC addresses also after U-Boot.
Specifically the MAC address of FEC (MC interface) would be incorrectly
set: 'ethaddr', which maps to the first I210 chip and is set to I210's
default address read from the driver by eth_write_hwaddr in eth_legacy.c
because the variable is undefined (not set even by bx50v3.c), would
result in the eth0 interface's MAC address to be set to I210's default
address.

Instead of programming the hardware directly in the board
implementation, follow the flow documented in doc/README.enetaddr: set
the enet[0-9]*addr environment variable and let the driver program the
hardware.
This avoids duplicating the implementation as it already exists in the
driver (drivers/net/fec_mxc.c: fec_set_hwaddr).
The mapping from the driver's index to the environment variable's name
is documented in README: Note for Redundant Ethernet Interfaces. It is
assumed that eth_devices for the controllers on the board are always
indexed in the same order, i.e. FEC always has the index 2.
The FEC driver does *not* set the flag Set MAC Address on Transmit (bit
set_eth0_mac_address used to do but this is unnecessary as the Linux
networking stack fills in the MAC address.
