So, there is no way to get a blob release with the patch applied ?
We know it is a bug in TF-A and if Rockchip is using that codebase, it
will be the same bug there too causing this issue. Waiting until the
code is released and the proper TF-A port is done may not be acceptable
for many developers. So someone from the rockchip doing these tf-a blob
release must get involved here, understand the situation and get the fixed.

We can workaround, but I want to hear that it will be fixed instead of
getting ignored until proper port is available.

Etienne, are you not the author for the related TF-A code ? How can we
get that fixed in the TF-A code base. If you are not, then I will try to
get my repo login credentials sorted so that I can only push TF-A change.
