Ayush Singh c1790b14bc uefi: Implement path ... UEFI paths can be of 4 types: 1. Absolute Shell Path: Uses shell mappings 2. Absolute Device Path: this is what we want 3: Relative root: path relative to the current root. 4: Relative Absolute shell path can be identified with `:` and Absolute Device path can be identified with `/`. Relative root path will start with `\`. The algorithm is mostly taken from edk2 UEFI shell implementation and is somewhat simple. Check for the path type in order. For Absolute Shell path, use `EFI_SHELL->GetDevicePathFromMap` to get a BorrowedDevicePath for the volume. For Relative paths, we use the current working directory to construct the new path. BorrowedDevicePath abstraction is needed to interact with `EFI_SHELL->GetDevicePathFromMap` which returns a Device Path Protocol with the lifetime of UEFI shell. Absolute Shell paths cannot exist if UEFI shell is missing. Signed-off-by: Ayush Singh <ayush@beagleboard.org>		2025-01-16 10:19:22 +05:30
