Javier Martinez Canillas c0e647eb0e util/mkimage: Fix wrong PE32+ section sizes for some arches 
The commit f60ba9e594 (util/mkimage: Refactor section setup to use a helper)
added a helper function to setup PE sections. But it also changed how the
raw data offsets were calculated since all the section sizes are aligned.
However, for some platforms, i.e ia64-efi and arm64-efi, the kernel image
size is not aligned using the section alignment. This leads to the situation
in which the mods section offset in its PE section header does not match its
real placement in the PE file. So, finally the GRUB is not able to locate
and load built-in modules.

The problem surfaces on ia64-efi and arm64-efi because both platforms
require additional relocation data which is added behind .bss section.
So, we have to add some padding behind this extra data to make the
beginning of mods section properly aligned in the PE file. Fix it by
aligning the kernel_size to the section alignment. That makes the sizes
and offsets in the PE section headers to match relevant sections in the
PE32+ binary file.

README 

This is GRUB 2, the second version of the GRand Unified Bootloader.
GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more
robust, more powerful, and more portable.

See the file NEWS for a description of recent changes to GRUB 2.

See the file INSTALL for instructions on how to build and install the
GRUB 2 data and program files.

Please visit the official web page of GRUB 2, for more information.
The URL is <http://www.gnu.org/software/grub/grub.html>.

More extensive documentation is available in the Info manual,
accessible using 'info grub' after building and installing GRUB 2.

There are a number of important user-visible differences from the
first version of GRUB, now known as GRUB Legacy. For a summary, please
see:
