# $FreeBSD$
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.

Add a version of the FreeBSD bootloader which can run in userland, packaged as a shared library. This is intended to be used by BHyVe to load FreeBSD kernels into new virtual machines.

SRCS+= boot.c commands.c console.c devopen.c disk.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.

SRCS+= interp_backslash.c interp_parse.c ls.c misc.c
Implement a simple LRU block cache. By default this is initialised to 16k, and will bypass transfers for more than 8k. Blocks are invalidated after 2 seconds, so removable media should not confuse the cache. The 8k threshold is a compromise; all UFS transfers performed by libstand are 8k or less, so large file reads thrash the cache. However many filesystem metadata operations are also performed using 8k blocks, so using a lower threshold gives poor performance. Those of you with an eye for cache algorithms are welcome to tell me how badly this one sucks; you can start with the 'bcachestats' command which will print the contents of the cache and access statistics.

Resynch with working sources before BTX integration. - Use format-independant module allocator. - Conditionalise ISA PnP support. - Simplify PnP enumerator interface. - Improve module/object searching. - Add missing depend/install targets in BTX makefiles. - Pass the kernel environment and module data in extended bootinfo fields. - Add a pointer to the end of the kernel + modules in bootinfo. - Fix parsing of old-style kernel arguments.

Separate out the ELF relocation code from the ELF loader, and add better relocation support for the amd64 and i386 platforms. This should not result in any change in functionality, but moves a step towards supporting the relocatable object file modules on amd64. The same hack/trick as load_elf*.c uses is used here to simultaneously support both elf32 and elf64 on amd64 and i386.

Provide support in loader for booting 64-bit PowerPC kernels. Like amd64, 64-bit PowerPC kernels are loaded by a 32-bit loader, since nearly all powerpc64 firmwares execute in 32-bit mode.

Introduce a new option (BOOT_PROMPT_123) that lets enter the boot prompt only when typing the sequence "123" (opposite to the standard 'push any button' approach). That results useful when using serial lines sending garbage and leading to unwilling boot prompt appearence.
