efi_loader: Remove

2023-12-21T13:54:37Z

We largely do not need in these files, so drop it. The only exception here is that efi_freestanding.c needs and had been getting that via . Reviewed-by: Simon Glass Signed-off-by: Tom Rini

efi_loader: simplify efi_str_to_u16()

efi_loader: fix display of NVMe EUI-64

2022-09-03T08:49:17Z

UEFI specification 2.9A requires to display the EUI-64 "in hexadecimal format with byte 7 first (i.e., on the left) and byte 0 last". This is in contrast to what the NVMe specification wants. But it is what EDK II has been implementing. Here is an example with the patch applied: qemu-system-aarch64 -machine virt -cpu cortex-a72 -nographic \ -bios denx/u-boot.bin \ -device nvme,id=nvme1,serial=9ff81223 \ -device nvme-ns,bus=nvme1,drive=nvme1n0,eui64=0x123456789ABCDEF0 \ -drive file=arm64.img,if=none,format=raw,id=nvme1n0 => nvme scan => efidebug devices Device Path ==================== /VenHw(…)/NVMe(0x1,f0-de-bc-9a-78-56-34-12) Signed-off-by: Heinrich Schuchardt

efi_loader: fix efi_convert_device_path_to_text()

2022-08-13T09:09:49Z

Ensure that the string we convert to UTF-16 is NUL terminated even if the device path only contains end nodes. Fixes: bd3d75bb0c58 ("efi_loader: multi part device paths to text") Addresses-Coverity: 350434 ("Uninitialized scalar variable") Signed-off-by: Heinrich Schuchardt

efi_loader: fix text output for Uart() DP nodes

2022-02-05T19:20:01Z

The UEFI specification concerning Uart() device path nodes has been clarified: Parity and stop bits can either both use keywords or both use numbers but numbers and keywords should not be mixed. Let's go for keywords as this is what EDK II does. For illegal values fall back to numbers. Signed-off-by: Heinrich Schuchardt

efi_loader: fix device path to text protocol

2022-02-05T19:20:01Z

The printing of a file path node must properly handle: * odd length of the device path node * UTF-16 character only partially contained in device path node * buffer overflow due to very long file path Signed-off-by: Heinrich Schuchardt
