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. 1998-08-21 03:17:42 +00:00			`# Options used when building app-specific libalpha components`
Overhaul makefiles. 2004-02-11 22:01:17 +00:00

Part 2 of fixing the boot code: gcc 3.4 fixes. The whole problem seems to be size. Which is odd, because it is said that size doesn't matter. Anyway... Add -Os to strategic places in the makefile to have the final loader be as mall as possible. This seems to be enough to make it work. For now... I think something is more fundamentally wrong; or something more fundamental is wrong. Potato, potaato. 2004-08-22 06:24:59 +00:00			`CFLAGS+= -ffreestanding -mno-fp-regs -Os`

Reclaim the 48k used by the first bootstrap stage by adding it to the malloc pool. 1998-10-19 09:12:41 +00:00			`PRIMARY_LOAD_ADDRESS= 0x20000000 # "Region 1 start"`
Backout revision 1.7 which was a bad idea since it would force people to reinstall boot1 after a 'make world'. Unfortunately this means that people who have already installed a new boot1 from a 'make world' after 2000/09/18 must reinstall it after their next build using something like: # disklabel -B /dev/da0c 2000-10-27 09:36:34 +00:00			`SECONDARY_LOAD_ADDRESS= 0x2000c000 # "Region 1 start" + 48k`

* Add old UFS compatibility code to alpha/boot1. * Fix a raft of warnings, printf and otherwise. * Allocate the correct amount in mod_searchmodule to prevent an overflow. * Fix the makefiles so they work outside my home directory (oops). 1998-09-26 10:51:38 +00:00			`LIBSTANDDIR= ${.CURDIR}/../../../../lib/libstand`
