# $FreeBSD$
This is the new unified bootstrap, sometimes known previously as the 'three-stage' bootstrap. There are a number of caveats with the code in its current state: - The i386 bootstrap only supports booting from a floppy. - The kernel and kld do not yet know how to deal with the extended information and module summary passed in. - PnP-based autodetection and demand loading of modules is not implemented. - i386 ELF kernel loading is not ready yet. - The i386 bootstrap is loaded via an ugly blockmap. On the alpha, both net- and disk-booting (SRM console machines only) is supported. No blockmaps are used by this code. Obtained from: Parts from the NetBSD/i386 standalone bootstrap.

SRCS+= boot.c commands.c console.c devopen.c interp.c
Enable the i386 loader to load and run an amd64 kernel. If this puts things over floppy size limits, I can exclude it for release builds or something like that. Most of the changes are to get the load_elf.c file into a seperate elf32_ or elf64_ namespace so that you can have two ELF loaders present at once. Note that for 64 bit kernels, it actually starts up the kernel already in 64 bit mode with paging enabled. This is really easy because we have a known minimum feature set. Of note is that for amd64, we have to pass in the bios int 15 0xe821 memory map because once in long mode, you absolutely cannot make VM86 calls. amd64 does not use 'struct bootinfo' at all. It is a pure loader metadata startup, just like sparc64 and powerpc. Much of the infrastructure to support this was adapted from sparc64.

These changes attempt to put things in order before the introduction of MIPS ubldr. The changes are mostly dealing with removing unnecessary casts from the U-Boot API (we're passing only pointers, no obvious reason to cast them to uint32_t), cleaning up some compiler warnings and using the proper printf format specifiers in order to be able to compile cleanly for both 32-bit and 64-bit MIPS targets.

${NEWVERSWHAT}
Install the 4th files in sys/boot/forth instead of each loader Also, move generation of loader.help into loader.mk. Set HELP_FILES= to disable this (so we only install one help file, for now). At the same time remove some duplicate -I lines. Fix several FILES= and CLEANFILES= into the += form since we're touching both of those in the .mk files. Make sure we only build one loader.help file per platform in a unified way (we were building many on some, with the last to install winning, though often they were the same text). Also, we're now installing loader.rc and menu.rc everywhere. arm and mips uboot installed these as menu.rc.sample, but there's no need since the loader.rc for those platforms doesn't do menu.rc processing by default. pcibios.4th is now installed everywhere, but will failsafe on non x86 platforms (it isn't loaded by default anywhere). These changes are too intertwined to do separately since aspects of each are required to have a bug-free commit. Sponsored by: Netflix
