The AM571x SoC has 1 GB DDR space. As part of normal re-location process U-Boot copies itself to the top of DDR bank. However, on HS devices, the top 0x2500000 is used by PPA and is firewalled. This results in an exception and the boot fails.
Fix this by reserving the top 0x2600000 memory (aligned to 2MB as per page size for ARM32) in defconfig and devicetree.
