The "U-Boot API", created by Rafal Jaworowsky , provides the hardware abstraction layer. Console is supported on serial port using the termios subsystem. This port supports, and indeed relies on, flattened device trees (FDT) - passed on from firmware, or loaded from a filesystem. My implementation use= s libfdt rather than trying to recycle the existing openfirmware code, and if possible I would like to keep it that way, and have libfdt included in GRUB= . libfdt is dual-licensed, GPLv2+/BSD, and the copyright belongs to David Gibson . I have a patch against the libfdt included in http://jdl.com/software/dtc-v1.3.0.tgz that makes it build under GRUB. The U-Boot API is released under GPLv2+ consists of 3 source files. They ar= e licensed under GPLv2+. The port also contains a crc32 checker I included from the FreeBSD loader, copyright Gary S. Brown with the statement that "You may use this program, or code or tables extracted from it, as desired without restriction.". The crc32 checker is not strictly speaking required, so could be removed if this poses any problems. In addition to this, the port includes libgcc helper functions (aeabi_*) taken from linux/arch/arm/lib, licensed under GPLv2+. My intent is to set up a public repository on launchpad.net containing my modifications on Monday. Do you have any opinions about how I should treat the third-party software when I do this?
