51f1357f34 Revert "drivers/crypto/fsl: assign job-rings to non-TrustZone"
Commit 22191ac353 ("drivers/crypto/fsl: assign job-rings to
 non-TrustZone") breaks HABv4 encrypted boot support in the
following i.MX devices:

- i.MX6UL
- i.MX7S
- i.MX7D
- i.MX7ULP

For preparing a HABv4 encrypted boot image it's necessary to
encapsulate the generated DEK in a blob. In devices listed
above the blob generation function takes into consideration
the Job Ring TrustZone ownership configuration (JROWN_NS)
and can be only decapsulated by the same configuration.

The ROM code expects DEK blobs encapsulated by the Secure World
environments which commonly have JROWN_NS = 0.

As U-Boot is running in Secure World we must have JROWN_NS = 0
so the blobs generated by dek_blob tool can be decapsulated
by the ROM code.

Job-rings assignment is now handled in OP-TEE OS, this commit can
be safely reverted.
https://github.com/OP-TEE/optee_os/pull/2986

This reverts commit 22191ac353.

08919d381c imx: Use a convenient default value for SYS_MALLOC_F_LEN
Commit 3a7c45f6a7 ("simple-bus: add DM_FLAG_PRE_RELOC flag to
simple-bus driver") causes some i.MX boards that were converted
to DM, such as warp7, to fail to boot.

As explained by Lukas Auer:

"With the patch, U-Boot probes the drivers for devices under simple-bus
device tree nodes in the pre-relocation device model. The default value
of CONFIG_SYS_MALLOC_F_LEN (0x400) leaves U-Boot with not enough memory to
do this, causing it to hang."

Fix this problem by providing a convenient default value for
CONFIG_SYS_MALLOC_F_LEN.

0633e13478 imx: hab: Increase CSF_SIZE for i.MX6 and i.MX7 devices
In certain i.MX devices the encrypted boot image is failing to boot.

According to AN12056 "Encrypted Boot on HABv4 and CAAM Enabled Devices"
it's necessary to pad CSF to 0x2000 and append DEK blob.

In this case the total image size in boot data structure must cover the
entire binary otherwise the dek_blob won't be copied to memory and image
won't be decrypted.

Increase CSF_SIZE to 0x4000 to avoid such issue when booting encrypted
boot images.

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.

7a69e97ba4 efi_loader: implement event queue
Up to now we have only been using a flag queued for events. But this does
not satisfy the requirements of the UEFI spec. Events must be notified in
the sequence of decreasing TPL level and within a TPL level in the sequence
of signaling.

Implement a queue for signaled events.
