Hi Scott Please add the platform specific flags as a field in fip_dev_state_t.

typedef struct { uintptr_t dev_spec; uint32_t plat_toc_flag; } fip_dev_state_t;

Then this field can be updated as part of verifying the FIP header. This header needs to be cleared when the device is closed.

Introduce a helper in fip driver to query the flags:

int fip_dev_get_plat_toc_flag(io_dev_info_t *dev_info, uint32_t *plat_toc_flag);

That should satisfy your requirement.

Thanks - we'll work making adjustments.

Hello,

The fip header has reserved fields available for platform specific use. The fiptool allows these header fields to be filled in using the --plat-toc-flags.

A call needs to be available in the ATF framework to get these flags without accessing the FIP file again to get these flags. We have a solution we've used for ATF for quite some time to access these flags.

It's finally being upstreamed here: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/2839

If there are any other efficient methods to access these flags or a better proposal please suggest.

Thanks, Scott -- TF-A mailing list TF-A@lists.trustedfirmware.org https://lists.trustedfirmware.org/mailman/listinfo/tf-a
