efi_loader: correct DeviceNodeToText for media types

2017-12-16T22:07:56+00:00

When converting device nodes and paths to text we should
stick to the UEFI spec.

efi_loader: add missing breaks

Otherwise with GUID partition types you would end up with things like:

  .../HD(Part0,Sig6252c819-4624-4995-8d16-abc9cd5d4130)/HD(Part0,MBRType=02,SigType=02)

efi_loader: fix efi_convert_device_node_to_text

2017-12-01T12:35:05+00:00

We need to implement to different functions for the
EFI_DEVICE_PATH_TO_TEXT_PROTOCOL:
ConvertDeviceNodeToText
ConvertDevicePathToText

A recent patch screwed up efi_convert_device_node_to_text
to expect a device path and not a node.

The patch makes both service functions work again.

efi_convert_device_node_to_text is renamed to
efi_convert_single_device_node_to_text and
efi_convert_device_node_to_text_ext is renamed to
efi_convert_device_node_to_text to avoid future
confusion.

A test of ConvertDeviceNodeToText will be provided in
a follow-up patch.

efi_loader: efi_dp_str should print path not node

2017-12-01T12:33:22+00:00

efi_dp_str is meant to print a device path and not a device
node.

The old coding only worked because efi_convert_device_node_to_text
was screwed up to expect paths instead of nodes.

efi_loader: size of media device path node represenation

2017-12-01T12:32:41+00:00

In the format specifier we want to specify the maximum width
in case an ending \0 is missing.

So slen must be used as precision and not as field width.

efi_loader: Add mem-mapped for fallback

2017-10-12T15:22:58+00:00

When we don't have a real device/image path, such as 'bootefi hello',
construct a mem-mapped device-path.

This fixes 'bootefi hello' after devicepath refactoring.

efi_loader: flesh out device-path to text

2017-09-20T08:32:54+00:00

It needs to handle more device-path node types, and also multiple levels
of path hierarchy.  To simplify this, initially construct utf8 string to
a temporary buffer, and then allocate the real utf16 buffer that is
returned.  This should be mostly for debugging or at least not critical-
path so an extra copy won't hurt, and is saner than the alternative.
