config BR2_PACKAGE_HOST_LZMA_ALONE bool "host lzma-alone" help LZMA has two well-known command-line tools: 1. lzma from LZMA SDK 2. lzma from XZ Utils (previously LZMA Utils) This package provides the former one which: 1. Gives more control over compression parameters 2. Gets named lzma_alone to allow coexistence This tool may be used to prepare firmwares for bootloaders with limited LZMA support. E.g. Broadcom's CFE bootloader for MIPS BCM47xx devices is known to fail to boot images using LZMA compression with dictionary. https://www.7-zip.org/sdk.html
