Why does the boot fail when > 512MB?
It is a limitation by BOOT ROM where it can not bring up the initial
bootloader when its size exceeds 512 KB in the DFU boot mode.
address this, the initial bootloader image has been optimized to be
smaller than 512 KB.
Therefore, limit the first OSPI partition size to 512 KB and adjust the
remaining size across the subsequent partitions.
I am NOT a fan of redoing flash partition organization of platforms that
are already in production - all kinds of ecosystem messes happen as a
result. Alternatively - give the 512K to u-boot tispl partition and
leave all others as is - this will at least allow people's current env
to be retained.
This sounds good to me. I will let Prasanth comment over this.
