[PATCH v1 0/2] imx8m: fix secure boot

[Heiko Schocher]

This series fixes secure boot on imx8m based boards. Tim
also detected this issue and the patches fixed on his hardware
also the problem, see discussion here:

https://lists.denx.de/pipermail/u-boot/2021-July/454351.html

Problem is that the IVT header gets loaded to a memallocated
buffer, but it needs to sit on memaddress coded in IVT header
itself. This patchseries adds a weak function spl_load_simple_fit()
in common spl code, which does not change current code behaviour.

Second patch than implements this weak function for imx based
boards (if no IVT header is found on address which is passed
to it, it does nothing).

I am not sure if this is the best solution, but it fixes a real
bug, and may could be made clearer, if possible.


Heiko Schocher (2):
  spl_fit. add hook to make fixes after fit header is loaded
  imx: spl: implement spl_load_simple_fit_fix_load
