> In case CONFIG_SECURE_BOOT is enabled we need to limit the SPL size to
> avoid a possible HAB failure event:
> --------- HAB Event 1 -----------------
> event data:
>         0xdb 0x00 0x14 0x42 0x33 0x22 0x33 0x00
>         0x00 0x00 0x00 0x0f 0x00 0x90 0x70 0x00
>         0x00 0x01 0x10 0x00
> STS = HAB_FAILURE (0x33)
> ENG = HAB_ENG_ANY (0x00)
> As explained in Commit 23612534fe0f ("spl: imx6: Provide a SPL_SIZE_LIMIT
> default") the i.MX6 SPL size limit is 68KB.
> The ROM code is copying the image size defined in boot data to its
> respective load address, in case we exceed the OCRAM free region a
> HAB invalid address failure event is generated.
> The maximum CSF size is defined in CONFIG_CSF_SIZE, reduce SPL size
> limit based on this configuration.
