cbc81b735e mx7ulp: Only enable LDO if it is not already enabled
LDO mode may be already enabled by the ROM and enabling it again
can cause U-Boot to hang.

Avoid this problem by only enabling LDO mode if it is initially disabled.

30b8eb5ee6 mx7ulp: soc: s_init should only be executed once
On SPL enabled systems, the current s_init code (wdog, clock and ldo
init) is executed twice (by SPL and u-boot). This is not necessary and
might lead to boot issues (ie, starting PMC1 when it is already running).

d714a75fd4 imx: replace CONFIG_SECURE_BOOT with CONFIG_IMX_HAB

7777406a8a i.MX7ULP: Fix system reset after a7 rtc alarm expired.
The board will reboot if A7 core enter mem mode by rtc, then M4 core
enter VLLS mode after the RTC alarm expired. Enable the dumb PMIC mode
to fix this issue.
Since i.MX7ULP B0 moves the SNVS LP into M4 domain, A core can't access
it. So check the CPU rev and not apply the settings for B0.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

552a848e4f imx: reorganize IMX code as other SOCs
Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.
