Call the TRNG init function at the end of arch_cpu_init()
Concerned SoCs are: i.MX6, i.MX7 and i.MX8MSigned-off-by: Aymen Sghaier
(cherry picked from commit 996329904c0304a7bfbc6cda8287ab93de77870d) -
The following reasons lead to instantiate the TRNG into U-Boot/SPL:
- On some i.MX platforms Linux Kernel could not instantiate RNG
- RNG could be used/needed by M4/M0 cores before Kernel stage
- Having the RNG instantiation implemented only once for
almost i.MX platformsSigned-off-by: Aymen Sghaier

Add the fsl CAAM driver and new commands to implement DEK blob operations,

The CONFIG_DEVRES is not a necessary config for pinctrl. We decouple the
dependence from the kconfig. So the DEVRES is not default enabled.When using DWC3 gadget driver, without enabling gadget DM driver, the calling
to devm_kzalloc will cause crash if CONFIG_DEVRES is set.Signed-off-by: Ye Li

We enabled the DM for xhci-imx8m driver which uses compatible string
"fsl, imx8mq-dwc3". But found a issue that u-boot will get four USB bus not two.
The reason is the low level driver xhci-dwc3 also adds the DM support which uses
compatible string "snps,dwc3". Thus, one USB node and its dwc3 subnode are both
binded as independent USB bus.Since the xhci-imx8m driver uses xhci-dwc3 as low level driver, to fix the issue
we add -u-boot.dtsi files to change the USB node compatible string to
"simple-bus" and change dwc3 node compatibe string to "fsl, imx8mq-dwc3". Then
xhci-dwc3 DM driver won't bind any node.Signed-off-by: Ye Li

Add DDR3 init codes, board codes, defconfig and DTS into u-boot.
Basic modules are ready: SD, UART, I2C, USB host and NAND.There is a FPGA on this board. It controls WDOG_B, and ENET PHY RESET.

Enable the SPL SDP for iMX8MM EVK. So that when booting from USB serial
download mode, the SPL will enter SDP to download FIT image from USB host
(uuu tool) and boot into FIT image.The SDP driver needs larger malloc pool size, so extend the SPL malloc pool
to 12KB and reduce the SPL BSS MAX to 4KB because BSS actual size is about 1KB.Signed-off-by: Ye Li

The u-boot 2018 forces to use gcc 6.0 or later to save binary size for some platforms.
This check causes problem for android building because android tool chain remains
using gcc 4.9.
Since iMX6/7/8 platforms don't meet binary size issue, we can remove the checkgcc6
and use old gcc.Signed-off-by: Ye Li

Add two DTS files, one for iMX8MM LPDDR4 EVK (fsl-imx8mm-evk.dts)
and another for iMX8MM DDR4 EVK.
Two boards share same base board, the major difference is the DDR4 board
installs NAND chip and removes flexspi and eMMC.Signed-off-by: Ye Li

Because we power off all devices in board_quiesce_devices which is prior then
executing dm_remove_devices_flags. So any access to HW in dm_remove_devices_flags
will cause problem.
However, some drivers like ethernet which implements the pre_remove callback is always
called without any flags check, and this finally accesses FEC controller.Since we don't need to remove all devices in u-boot before starting kernel, disable
this feature when power domain is enabled.Signed-off-by: Ye Li

On iMX8MM, the V flag in TRISTR register only reflect the state of SNSR
value, not the calibrated TEMP value. So checking this flag is not
reliable. Per IC suggestion, change to read the TEMP/AVG_TEMP directly
and check whether it in valid range 10-125C.Signed-off-by: Ye Li

When the temperature is out of sensor's range, the Valid bit won't be

The analog sensors on iMX8MM are new, used for 14LPP process. So the

The imx8mm has changed the address of rvt_hab, use new address for imx8mm.
The authentication procedure is same as imx8mq. In u-boot, the authentication
uses SIP call to trap ATF to run HAB authenticate.
