The motivation for moving MX23 selection to Kconfig is to be able
to better handle NAND MXS selection through Kconfig.

This selection method also aligns with the way other i.MX SoCs are
selected in U-Boot.

Follow bootz's pattern by moving the booti_setup to arch/arm/lib.
This allows to use booti_setup in other paths, e.g booting
an Android image containing Image format.

Note that kernel relocation is move out of booti_setup and it is the
caller's responsibility to do it and allows them do it differently. say,
cmd/booti.c just do a manually, while in the bootm path, we can use
bootm_load_os(with some changes).

'default' on a choice refers to the symbol selected by default, not to
the choice mode, so 'default n' is meaningless.

No functional changes. Optional choices implicitly default to n mode
(and there is no way to make them default to another mode).

FreeBSD, like OpenBSD, uses BIG_ENDIAN, LITTLE_ENDIAN, and BYTE_ORDER,
whereas Linux and compatibles use __-prefixed names.  Define the names
the same as the OpenBSD block below it.

cmd/Makefile has:

ifdef CONFIG_FPGA
obj-$(CONFIG_CMD_FPGA) += fpga.o
endif

which means that if CONFIG_FPGA is not set, CONFIG_CMD_FPGA silently
does nothing. Let's remove that Makefile conditional and instead express
this equivalent dependency in Kconfig, so a lot of redundant

 # CONFIG_CMD_FPGA is not set

can be removed from board defconfigs that don't actually have an FPGA.

In most places in the code we cast this to an unsigned long, but in one
place we cast to an unsigned int.  For consistency and to fix a warning
on 64bit targets, always cast this to unsigned long.  For the long term

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.
