1SUMMARY="Boot loader for embedded boards" 2DESCRIPTION="boot loader for embedded boards based on PowerPC, ARM, MIPS and several other \ 3processors, which can be installed in a boot ROM and used to \ 4initialize and test the hardware or to download and run application code. 5 6The development of U-Boot is closely related to Linux: some parts of \ 7the source code originate in the Linux source tree, we have some \ 8header files in common, and special provision has been made to \ 9support booting of Linux images. 10 11Some attention has been paid to make this software easily \ 12configurable and extendable. For instance, all monitor commands are \ 13implemented with the same call interface, so that it's very easy to \ 14add new commands. Also, instead of permanently adding rarely used \ 15code (for instance hardware test utilities) to the monitor, you can \ 16load and run it dynamically." 17HOMEPAGE="https://www.denx.de/wiki/U-Boot" 18COPYRIGHT="2000-2024 Wolfgang Denk, DENX Software Engineering" 19LICENSE="GNU GPL v2" 20REVISION="1" 21SOURCE_URI="https://ftp.denx.de/pub/u-boot/u-boot-$portVersion.tar.bz2" 22SOURCE_DIR="u-boot-$portVersion" 23CHECKSUM_SHA256="18a853fe39fad7ad03a90cc2d4275aeaed6da69735defac3492b80508843dd4a" 24PATCHES="u_boot-$portVersion.patchset" 25 26ARCHITECTURES="any" 27 28PROVIDES=" 29 u_boot$secondaryArchSuffix = $portVersion 30 " 31REQUIRES=" 32 " 33 34# The package is "any" because the result is only binaries.
