7ce134b7c3 board: toradex: add colibri imx8qxp 2gb wb it v1.0b module support
This commit adds initial support for the Toradex Colibri iMX8QXP 2GB WB
IT V1.0B module. Unlike the V1.0A early access samples exclusively
booting from SD card, they are now strapped to boot from eFuses which
are factory fused to properly boot from their on-module eMMC. U-Boot
supports either booting from the on-module eMMC or may be used for
recovery purpose using the universal update utility (uuu) aka mfgtools
3.0.

Functionality wise the following is known to be working:
- eMMC and MMC/SD card
- Ethernet
- GPIOs
- I2C

Unfortunately, there is no USB functionality for the i.MX 8QXP as of
yet.

4c45e43a2a imx: fix building for i.mx8 without spl
Building with Travis CI complained and stopped with the following error:
+cc1: fatal error: opening output file spl/u-boot-spl.cfgout: No such

+compilation terminated.

This fixes commit caceb739ea ("imx: build flash.bin for i.MX8") which
took SPL being enabled on i.MX8 for granted.

Add a CONFIG_SPL_BUILD for passover usage, no need to execute it again

U-Boot stage, need to make the passover code executed after

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  |
|     |     |     |   |           |     |        |

 - SoC goes into DSM mode;
 - DDR goes into self-refresh mode;
 - CPU0/SCU will be powered down.

When wake up event arrives:

 - SoC DSM mdoe exits;
 - CA7 platform exit STOP mode, SCU/CPU0 power up;
 - Invalidate L1 cache;
 - DDR exit self-refresh mode;
 - Do secure monitor mode related initialization;
 - Jump to linux kernel resume entry.

Belwo is the log of 1 iteration of system suspend/resume:

08a00cba06 dm: Change CMD_DM enabling
CMD_DM is used for debug purpose and it shouldn't be enabled by default
via Kconfig. Unfortunately this is in the tree for quite a long time
that's why solution is to use imply DM for all targets which are
enabling DM.

bbbb50f9fd imx: i.mx6q: imx6q_logic: Migrate to SPL and enable SDP
Since the vast majority of i.MX6 boards are migrating to SPL,
this patch converts im6q_logic to SPL and enables the SDP for
loading SPL and u-boot.img over USB.  The Falcon mode only
supports NAND flash as of now due to limited space/RAM, but
all i.MX6D/Q SOM's from Logic PD have internal NAND from which
to boot.

d5b7177f91 pico-imx7d: Add SPL support
Convert pico-imx7d to SPL support.

There are two variants of pico-imx7d SOMs:
- One with 512MB of RAM
- One with 1GB of RAM

The 512MB module contains two Hynix H5TC2G63GFR-PBA.
The 1GB module contains two Hynix H5TC4G63GFR-PBA.

The RAM size is determined in runtime by reading GPIO1_12.

While at it, also add USB Serial Download mode support as it
is very helpful for loading SPL and u-boot.img via imx_usb_loader.

a89eb89b38 imx: mx7: psci: provide complete PSCI 1.0 implementation
PSCI 1.0 require PSCI_VERSION, PSCI_FEATURES, AFFINITY_INFO and
CPU_SUSPEND to be implemented. Commit 0ec3d98f76 ("mx7_common:
use psci 1.0 instead of 0.1") marked the i.MX 7 implementation to
be PSCI 1.0 compliant but failed to implement those functions.
Especially the missing PSCI version callback was noticeable when
booting Linux:

  [    0.000000] psci: probing for conduit method from DT.
  [    0.000000] psci: PSCIv65535.65535 detected in firmware.
  [    0.000000] psci: Using standard PSCI v0.2 function IDs
  [    0.000000] psci: MIGRATE_INFO_TYPE not supported.
  [    0.000000] psci: SMC Calling Convention v1.0

This patch provides a minimal implementation thereof. With this
patch applied Linux detects PSCI 1.0:

  [    0.000000] psci: probing for conduit method from DT.
  [    0.000000] psci: PSCIv1.0 detected in firmware.
  [    0.000000] psci: Using standard PSCI v0.2 function IDs
  [    0.000000] psci: MIGRATE_INFO_TYPE not supported.
  [    0.000000] psci: SMC Calling Convention v1.0
