[PATCH 00/13] efi: Tidy up confusion between pointers and addresses

[Simon Glass]

The EFI-loader implementation converts things back and forth between
addresses and pointers, with not much consistency in how this is done.

Within most of U-Boot a pointer is a void * and an address is a ulong

This convention is very helpful, since it is obvious in common code as
to whether you need to call map_sysmem() and friends, or not.

As part of cleaning up the EFI memory-management, I found it almost
impossible to know in some cases whether something is an address or a
pointer. I decided to give up on that and come back to it when this is
resolved.

This series starts applying the normal ulong/void * convention to the
EFI_loader code, so making things easier to follow.
