Add basic i.MX8ULP support For the MMU part, Using a simple way the calculate the MMU size to avoid default heavy calcaulation. And align address and size in the table settings to 2MB or 4GB as much as possible. So we can reduce the 4K page allocations in MMU table which will spends much time in create the page table Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
