Hi,
I am trying to use the HAB functionality on an i.MX6SX processor.
I have enabled HAB support in U-Boot (`CONFIG_IMX_HAB`).
I was able to sign the image using the fast authentication method with the following configuration:
```
[Header]
Version = 4.2
Hash Algorithm = sha256
Engine Configuration = 0
Certificate Format = X509
Signature Format = CMS
Engine = ANY
[Install SRK]
# Index of the key location in the SRK table to be installed
File = "../../crts/SRK_1_2_3_4_table.bin"
Source index = 0
[Install NOCAK]
File = "../../crts/SRK1_sha256_2048_65537_v3_usr_crt.pem"
[Authenticate CSF]
[Unlock]
Engine = CAAM
Features = RNG
[Authenticate Data]
# Key slot index 0 used to authenticate the image data
Verification index = 0
# Authenticate Start Address, Offset, Length, and file
Blocks = 0x00907400 0x00000000 0x0000ec00 "SPL"
```
Unfortunately, it doesn't work. The `hab_status` command outputs the following errors:
```
Secure boot disabled

```
The addresses referenced in the error messages point to the MMU table, which is located outside the OCRAM region.
What could be causing this issue?
