Add new u-boot command "imx_tamper" to configure and check the tamper pins.
The codes are used for reference and test. So command is disabled at default,
user can enable it by adding CONFIG_IMX_TAMPER=y to defconfigThe iMX7D has 10 tamper pins those can be used for SNVS tamper detection.
Tamper 9 pin is NVCC_DRAM power switch for LPSR by default.
It must be fused to tamper function by command
=> fuse prog -y 1 3 0x80000000
Otherwise, SNVS power consumption would be highWhen tamper is detected, CPU can't enter/stay in SNVS mode,
the tamper must be cleared and disabled before enter SNVS.Signed-off-by: Ye Li

Because the ROM info on iMX7D does not set device type to USB when booting
from serial download mode, we have to use the mechanism on mx6 to implement
the is_boot_from_usb. The original implementation is checking USB controller
register, it can't work correctly after any USB functionality is run in u-boot.Signed-off-by: Ye Li

According to the Cortex-A7 TRM, for ACTLR.SMP bit "You must ensure this bit
is set to 1 before the caches and MMU are enabled, or any cache and TLB
maintenance operations are performed".
ROM sets this bit in normal boot flow, but when in serial download mode, it is not set.
Here we add it in u-boot as a common flow for all i.MX cortex-a7 platforms,
including mx7d, mx6ul/ull and mx7ulp.Signed-off-by: Ye Li

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.Signed-off-by: Bryan O'Donoghue

imx_set_wdog_powerdown() is always used to disable the power down
enable bit, so remove the boolean parameter of the function.It is also a bit strange to write a boolean value into registers,

At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.Also expand the help for the 'nowhere' option and move it to the top since
it is the default.Signed-off-by: Simon Glass

This converts the following to Kconfig:
CONFIG_ENV_IS_IN_MMC
CONFIG_ENV_IS_IN_NAND
CONFIG_ENV_IS_IN_UBI
CONFIG_ENV_IS_NOWHEREIn fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC
And then manual updates. This is because for CHAIN_OF_TRUST boards they
can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic
now.Signed-off-by: Simon Glass
