The alignment of sections in the EFI binaries generated by U-Boot is incorrect. According to the PE-COFF specification [1] the minimum value for FileAlignment is 512. If the value of SectionAlignment is less then the page size, it must equal FileAlignment. Let's set both values to 512 for the ARM and RISC-V architectures.
