efi_loader: create root node

2018-09-23T19:55:31+00:00

Currently we assign a lot of protocols to loaded images though
these protocols are not related to them. Instead they should be
installed on a separate handle. Via the device path it is the
parent to the devices like the network adapter.

Remove includes and PRI* usages in printf() entirely

2018-09-11T00:48:17+00:00

In int-ll64.h, we always use the following typedefs:

  typedef unsigned int         u32;
  typedef unsigned long        uintptr_t;
  typedef unsigned long long   u64;

This does not need to match to the compiler's .
Do not include it.

The use of PRI* makes the code super-ugly.  You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

efi_loader: correcty determine total device path length

2018-04-23T19:34:28+00:00

Device paths may consist of multiple instances. Up to now we have only
considered the size of the first instance. For the services of the
EFI_DEVICE_PATH_UTILITIES_PROTOCOL in most cases the total length of the
device path is relevant.

So let's rename efi_dp_size() to efi_dp_instance_size() and create a new
function efi_dp_size() that calculates the total device path length.

efi_loader: correctly determine length of empty device path

2018-04-23T19:34:28+00:00

efi_dp_size() is meant to return the device path length without the end
node.

The length of a device path containing only an end node was incorrectly
reported as 4.

efi_loader: fix AppendDevicePath

2018-04-23T19:34:28+00:00

The logic of the AppendDevicePath service of the
EFI_DEVICE_PATH_UTILITIES_PROTOCOL is incorrectly implemented:

* if both paths are NULL an end node has to be returned
* if both paths are not NULL the end node of the second device path has to
  be kept
