Add the new cdldr CD bootstrap loader. This patch includes the following: - Fix btxldr to preserve a NULL bootinfo pointer when it copies the kernel arguments. - Add the cdldr bootstrap program. This program is tacked onto the beginning of the standard 3rd stage boot loader (/boot/loader) to form the CD boot loader (/boot/cdboot). When a CD is booted, the cdboot file is copied into memory instead and executed. The cdldr stub emulates the environment normally provided by boot2 and then starts the loader. This booting method does not emulate a floppy drive, but boots directly off of the CD. This should fix the problems some BIOS's have with emulating a 2.88 MB floppy image. - Add support to the loader to recognize that it has been booted by cdldr instead of boot2 and use a simpler method of extracting the BIOS boot device. 2000-01-27 21:21:01 +00:00			`# $FreeBSD$`

Simplify the building of our i386 'binary' boot components by directly producing them using 'ld' options rather than post-processing with 'objcopy'. Idea by: Ryan Sommers <ryans@gamersimpact.com> 2004-04-25 19:50:20 +00:00			`PROG= ${BOOT}`
- Factor out -nostdlib to an upper level Makefile.inc. - Now that bsd.prog.mk deals with programs linked with -nostdlib better, and has a notion of an "internal" program, use PROG where possible. This has a good impact on the contents of .depend files and causes programs to be linked with cc(1). XXX: boot2 couldn't be converted as it's actually two programs. Tested on: i386, amd64 2004-02-09 14:11:58 +00:00			`INTERNALPROG=`
First round of cleanups to sys/boot/ makefiles: - do not use PROG for what's not a real C program, - use sys.mk transformation rules where possible, - only create the "machine" symlink on AMD64, - removed MAINTAINER lines in individual makefiles, - added the LIBSTAND defitinion to <bsd.libnames.mk>, - somewhat better contents in .depend files.

Use a more compact syntax for passing the "binary" options to 'ld'. 2004-04-25 20:36:44 +00:00			`LDFLAGS=-N -e start -Ttext ${ORG} -Wl,-S,--oformat,binary`
