While generating the page tables, a running integer index is shifted by SECTION_SHIFT (29) and causes overflow for any integer bigger than 7. The page tables therefore alias to the same 8 sections and cause U-Boot to hang once the MMU is enabled. Fix this by making the index a 64-bit unsigned integer and so avoid the overflow. swarren notes: currently "i" ranges from 0..8191 on all ARM64 boards, and "j" varies depending on RAM size; from 4 to 11 for a board with 4GB at physical address 2GB, as some Tegra boards have.
