a TODO to clean this up.

riscv: Add support for HI20 PE relocations

2018-06-14T08:52:14+00:00

The PE standard allows for HI20/LOW12 relocations. Within the efi_loader
target we always know that our relocation target is 4k aligned, so we
don't need to worry about the LOW12 part.

This patch adds support for the respective relocations. With this and a
few grub patches I have cooking in parallel I'm able to run grub on RISC-V.

efi_loader: Fix warning in raw/cols query

2018-06-03T13:51:19+00:00

The code to determine rows / cols on the screen could potentially run
into a case where it doesn't know how big the screen is. In that case,
assume 80x25.

efi_loader: create handles from normal memory

2018-06-03T13:27:21+00:00

Handles are not used at runtime. They are freed by the firmware when the
last protocol interface is uninstalled. So there is no reason to use EFI
memory when creating handles.

efi_loader: efi_mem_carve_out should return s64

2018-06-03T13:27:21+00:00

efi_mem_carve_out() is used to remove memory pages from a mapping.
As the number of pages to be removed is a 64bit type the return type
should be 64bit too.

efi_loader: DocBook comments for boot services

2018-06-03T13:27:21+00:00

With 'make htmldocs' we can generate a documentation if the function
comments follow the DocBook conventions.

This patch adjusts the comments for EFI boot services and provides the
DocBook template for the EFI subsystem.
