Bring in EDK2 routines for printing and parsing device paths. This commit implements the (mostly?) Linux compatible efidp_format_device_path and efidp_parse_device_path APIs. These are the only APIs exposed through this library. However, they are built on code from Tianocore's EDK2 MdePkg. They are brought in as new files here for reasons described in FreeBSD-update. Symbol versioning will be introduced to control what's exported from the EDK2 code. Some structural changes may be necessary when we move to sharing with sys/boot/efi. Sponsored by: Netflix

Fix printing File() nodes in device paths. Device paths encoded into the FILEPATH_DEVICE_PATH are UCS2 not ASCII/UTF8. Convert to utf8 and print that when printing File paths. Also, since File may be at the end of a long device path, output File() around the path so it doesn't just show up as random nodes that might accidentally match real node paths names and cause errors.

Fix printing File() nodes in device paths. Device paths encoded into the FILEPATH_DEVICE_PATH are UCS2 not ASCII/UTF8. Convert to utf8 and print that when printing File paths. Also, since File may be at the end of a long device path, output File() around the path so it doesn't just show up as random nodes that might accidentally match real node paths names and cause errors.

Bring in EDK2 routines for printing and parsing device paths. This commit implements the (mostly?) Linux compatible efidp_format_device_path and efidp_parse_device_path APIs. These are the only APIs exposed through this library. However, they are built on code from Tianocore's EDK2 MdePkg. They are brought in as new files here for reasons described in FreeBSD-update. Symbol versioning will be introduced to control what's exported from the EDK2 code. Some structural changes may be necessary when we move to sharing with sys/boot/efi. Sponsored by: Netflix

Bring in EDK2 routines for printing and parsing device paths. This commit implements the (mostly?) Linux compatible efidp_format_device_path and efidp_parse_device_path APIs. These are the only APIs exposed through this library. However, they are built on code from Tianocore's EDK2 MdePkg. They are brought in as new files here for reasons described in FreeBSD-update. Symbol versioning will be introduced to control what's exported from the EDK2 code. Some structural changes may be necessary when we move to sharing with sys/boot/efi. Sponsored by: Netflix

Implement efidp_size efidp_size will return the size, in bytes, of a EFI device path structure. This is a convenience wrapper in the same style as the other linux routines. It's implemented by GetDevicePathSize from EDK2 we already needed for other things. Sponsored by: Netflix

Add efidp_format_device_path_node to format a single node in a device path, much like efidp_format_device_path will format the entire path. Sponsored by: Netflix

Create a function to translate UEFI paths to unix paths efivar_device_path_to_unix_path translates from UEFI to Unix efivar_unix_path_to_device_path translates from Unix to UEFI At present, only HD() device types are supported (both GPT and MBR). CdRom and floppy devices aren't supported. ZFS isn't supported because there's no way in the UEFI standard to specify a ZFS datastore. Network devices aren't supported either. Three forms of Unix path are accepted: /path/to/file (for a mounted filesystem), //path/to/file (uses the EFI partition on the same disk as /), and dev:/path/to/file (for unmounted filesystem). Two forms are produced (the first and last). Sponsored by: Netflix
