From bfe220c4cc9463d9f8bfee5a600d94873d23d949 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Wed, 2 Aug 2023 20:12:21 +0000 Subject: [PATCH] include/efi: Include BMP and BLT header macro definitions This patch adds BMP image header and BLT header macros in `efi_datatype.h` to implement a converter inside coreboot FSP 2.0 driver that converts any input *.BMP image into the BLT buffer. The output BLT buffer is used by FSP-S to render any pre-boot display. Added `Bmp.h` and `GraphicsOutput.h` files for `UDK base >= 2017`, as these files were added with the UDK version 2017. Note: BLT in UEFI BMP implementation stands for `Bit-block transfer`. It is a method of copying graphis data (specifically images and fonts) from one location to another (framebuffer), where the data is stored in blocks of bits.
