efi_loader: efi_dp_from_lo() should skip VenMedia node

2021-10-21T01:46:04+00:00

The 'efidebug boot dump' command should not display the VenMedia() device
path node preceding the device path of the initial ram disk.

By letting efi_dp_from_lo() skip the VenMedia() device path node we can
simplify the coding.

efi_loader: efi_dp_from_lo() unused parameter size

2021-10-21T01:46:04+00:00

Parameter size is never used in function efi_dp_from_lo(). Remove it.

efi_loader: efi_dp_from_lo() don't copy GUID

2021-10-21T01:46:04+00:00

Instead of copying a GUID and then using a pointer to the copy for calling
guidcmp(), just pass the pointer to the orginal GUID.

efi_loader: Drop code that doesn't work with driver model

2021-10-21T01:46:03+00:00

This code should never have been added as it builds a new feature on top
of legacy code. This has already been improved with the dependency on BLK.

Add a dependency on DM_ETH also, to avoid needing to deal with this old
code.

Boards which want EFI_LOADER should migrate to driver model first.

efi_loader: use EfiBootServicesData for device path

2021-08-17T15:24:08+00:00

dp_alloc() was using a constant from the wrong enum resulting in creating
device paths in EfiReservedMemory.

efi_loader: set partition GUID in device path for SIG_TYPE_GUID

2021-07-18T12:43:56+00:00

Previously, the GPT device GUID was being used instead of the partition,
which was incorrect.

Let EFI_LOADER select CONFIG_PARTITION_UUIDS.
Use log_warning() instead of printf() for warning.

efi_loader: path length in efi_dp_from_name()

2021-05-25T11:06:57+00:00

Before this patch efi_dp_from_name() only accommodated a maximum file path
length of 31 characters. This leads to boot failures due to file name
truncation.

Allow arbitrary path lengths.

efi_loader: Add device path related functions for initrd via Boot####

2021-03-25T19:14:25+00:00

On the following patches we allow for an initrd path to be stored in
Boot#### variables.  Specifically we encode in the FIlePathList[] of
the EFI_LOAD_OPTIONS for each Boot#### variable.

The FilePathList[] array looks like this:
kernel - 0xff - VenMedia(initrd GUID) - initrd1 - 0x01 initrd2 - 0xff
So let's add the relevant functions to concatenate and retrieve a device
path based on a Vendor GUID.

efi_loader: Uart device path

2021-03-25T19:09:17+00:00

When uploading an EFI binary via the UART we need to assign a device path.

* Provide devicepath node to text conversion for Uart() node.
* Provide function to create Uart() device path.
* Add UART support to efi_dp_from_name().
