ELF loader, part 1. It works with ELF kernels generated on the i386 so far, and should probably be able to be made to work for the alpha without too much trouble once it's connected up and my assumptions tested. I think (but have not tested) it will also load "old" ELF kernels that were not linked with DYNAMIC headers. The module glue is yet to come. (oh fun.. :-) It does not explicitly load symbols [yet]. The _DYNAMIC data contains a runtime symbol set that ddb can use via ddb/db_kld.c. It'll be missing some detail that stabs normally provides (eg: number of args to a function, line numbers, etc). On the other hand, those minimal symbols will always be available even on a stripped kernel. This is mostly stolen from load_aout.c with some ideas from alpha/libalpha/elf_freebsd.c.

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.

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.
