Enabling capsule update functionality on the platform requires

Hi Sugosh,
Sorry for the late review.
+#define STM32MP15_DK2_FIP_IMAGE_GUID \
Although this is now only supported on this STM32MP15_DK2 board, I don't
think this macro should be tight to the board name, as it may be used
for other STM32MP boards. I'd just use STM32MP_FIP_IMAGE_GUID.
This should be the same for the fw_images[0].fw_name.
The idea of this GUID is to identify or associate an image with a
platform. Will the FIP image be common across multiple STM32MP
platforms? If we use a common GUID that might be shared across
multiple ST boards, it would be possible to flash an image generated
for the ev1 board on the dk2 board. However, you would know better
about ST platforms. So I can change this as per your suggestion.
Thanks.

Hi Sughosh,
This GUID is generic in TF-A for all STM32MP platforms.
Having a per board GUID in U-Boot might then be an issue.
And we'll end up with lots of GUIDs for each new board that will support
FWU.
But maybe I miss something here.
Yann
Best regards,
Yann
