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.

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.

efi_loader: fix off-by-one bug in efi_get_variable

2018-06-03T13:27:20+00:00

efi_get_variable() always stores an extra zero byte after the output data.
When the returned data size matches the output buffer size, the extra zero
byte is stored past the end of the output buffer.

efi_loader: avoid using unitialized values as console size

2018-06-03T13:27:20+00:00

If a request for the console size would be answered with a response
with less then three values, uninitialized stack memory would be
copied to the number of rows and columns of the terminal.
