75cd09cb18 imx8qxp: Fix the reported CPU frequency
Currently the CPU frequency is incorrectly reported:

CPU:   NXP i.MX8QXP RevB A35 at 147228 MHz

Fix this problem by using a direct call to the SCU firmware to
retrieve the Cortex A35 CPU frequency.

With this change applied the CPU frequency is displayed correctly:

CPU:   NXP i.MX8QXP RevB A35 at 1200 MHz

move get_cpu_rev out of CONFIG_CPU to avoid build failure when using

Add a CONFIG_SPL_BUILD for passover usage, no need to execute it again
in normal U-Boot stage. Also if still checking passover info in normal
U-Boot stage, need to make the passover code executed after
arch_cpu_init_dm.

528915c717 imx: Fix potential lmb memory overwritten by stack
At default, u-boot reserves the memory from SP - 4KB to DRAM end for
lmb in arch_lmb_reserve. So lmb won't allocate any memory from it.
But we found the 4K gap for SP is not enough now, because some FDT
updating operations are added in our u-boot before jumping to kernel,
which needs larger stack. This causes the lmb allocated memory is overwritten
by stack.

Fix the issue by implementing the board_lmb_reserve to reserve from
SP - 16KB to memory end for lmb.

b2ca8907d9 imx: hab: Convert non-NULL IVT DCD pointer warning to an error
The following NXP application notes and manual recommend to ensure the
IVT DCD pointer is Null prior to calling HAB API authenticate_image()
function:

- AN12263: HABv4 RVT Guidelines and Recommendations
- AN4581: Secure Boot on i.MX50, i.MX53, i.MX 6 and i.MX7 Series using
  HABv4
- CST docs: High Assurance Boot Version 4 Application Programming
  Interface Reference Manual

Commit ca89df7dd4 ("imx: hab: Convert DCD non-NULL error to warning")
converted DCD non-NULL error to warning due to the lack of documentation
at the time of first patch submission. We have warned U-Boot users since
v2018.03, and it makes sense now to follow the NXP recommendation to
ensure the IVT DCD pointer is Null.

DCD commands should only be present in the initial boot image loaded by
the SoC ROM. Starting in HAB v4.3.7 the HAB code  will generate an error
if a DCD pointer is present in an image being authenticated by calling the
HAB RVT API. Older versions of HAB will process and run DCD if it is
present, and this could lead to an incorrect authentication boot flow.

ea91031b22 imx: hab: extend hab_auth_img to calculate ivt_offset
Current implementation of hab_auth_img command needs ivt_offset to
authenticate the image. But ivt header is placed at the end of image
date after padding.

This leaves the usage of hab_auth_img command to fixed size or static
offset for ivt header. New function "get_image_ivt_offset" is introduced
to find the ivt offset during runtime. The case conditional check in this
function is same as boot_get_kernel in common/bootm.c

With this variable length image e.g. FIT image with any random size can
have IVT at the end and ivt_offset option can be left optional

Can be used as "hab_auth_img $loadaddr $filesize" from u-boot script

e246bfcfe2 SPL: Add HAB image authentication to FIT
Introduce two board level callback functions to FIT image loading process, and
a SPL_FIT_FOUND flag to differentiate FIT image or RAW image.

Implement functions in imx common SPL codes to call HAB funtion
to authenticate the FIT image. Generally, we have to sign multiple regions
in FIT image:
1. Sign FIT FDT data (configuration)
2. Sign FIT external data (Sub-images)

Because the CSF supports to sign multiple memory blocks, so that we can use one
signature to cover all regions in FIT image and only authenticate once.
The authentication should be done after the entire FIT image is loaded into
memory including all sub-images.
We use "-p" option to generate FIT image to reserve a space for FIT IVT
and FIT CSF, also this help to fix the offset of the external data (u-boot-nodtb.bin,
ATF, u-boot DTB).

The signed FIT image layout is as below:
--------------------------------------------------
|     |     |     |   |           |     |        |
| FIT | FIT | FIT |   | U-BOOT    | ATF | U-BOOT |
| FDT | IVT | CSF |   | nodtb.bin |     |   DTB  |
|     |     |     |   |           |     |        |

d79611598f imx: mkimage: avoid stop CI when required files not exists
Introduce a new script to check whether file exists and
use that check in Makefile to avoid break CI system.

The script return 1 when the required files not exists, return 0
when files exists. The script will ignore check to u-boot-dtb.bin,
because if there is something wrong to generate u-boot-dtb.bin,
there must be some code error.

be277c3a89 imx: mx7: avoid some initialization if low level is skipped
We can have the case where u-boot is launched after some other low level
enabler, like for example when u-boot runs after arm-trusted-firmware
and/or optee. So, because of that we may need to jump the initialization of
some IP blocks even because we may no longer have the permission for that.

So, if the config option to skip low level init is set disable also timer,
board and csu initialization.

0e5c8ce734 arm: imx: include imx8image support
When building i.MX8/8X board, use imx8image type.

`-e $(CONFIG_SYS_TEXT_BASE)` is not needed, but
no harm to keep it for i.MX8/8X
