* i386: Make boot loader smaller by reducing size of bootinfoWarner Losh2022-09-161-12/+3
| | | | | | | | | | | | | | | | | | | We don't need the 56 bytes at the end of bootinfo, and never had. Don't copy them from old boot loaders, and don't provide them with new boot loaders. Add comments about what versions of FreeBSD 'old' means in various contexts. Add note that old disk loader (from 1.x/2.x) is doomed to failure because it doesn't provide metadata that we now require to boot, and has been since approximately FreeBSD 7.x. Retain all this information to explain why we have 4 arguments that are always 0, even though it's ancient history. This saves 56 bytes in the boot loader.

* i386: Mark the obsolete fields in bootinfo with _was_Warner Losh2022-09-161-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | Mark the obsolete fields in bootinfo with _was_. Note that the fields from bi_memdesc_version to the end of the structure never were used in a release. They were added in April 2010 for i386 EFI booting. The boot loader set these fields though 2019, but no kernel ever looked at them and we never supported i386 EFI booting, and likely never will in this form. They can likely be deleted entirely in the future, but locore.S needs to change to do that (it also needs to change to drop support for really old booting scenarios as well, which will eliminate bi_endcommon too). All the other fields haven't been used since the 4.x -> 5.x cutover of the wdc driver to ata. The bi_bios_dev field is used in the handoff between bootXX and the loader. The loader uses it to determine what disk it was loaded off of to detmerine the default root filesystem. It's not used by the i386 kernel anymore to determine anything.

* sys/i386: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326260

* Load the kernel symbol table in the boot loader and not at compile time.Bruce Evans1995-01-251-10/+29

Make it easier to extend `struct bootinfo' without losing either forwards or backwards compatibility. ddb_aout.c: Get the symbol table from wherever the loader put it. Nuke db_symtab[SYMTAB_SPACE]. boot.c: Enable loading of symbols. Align them on a page boundary. Add printfs about the symbol table sizes. Pass the memory sizes to the kernel. Fix initialization of `unit' (it got moved out of the loop). Fix adding the bss size (it got moved inside an ifdef). Initialize serial port when RB_SERIAL is toggled on. Fix comments. Clean up formatting of recently added code. io.c: Clean up formatting of recently added code. netboot/main.c, machdep.c, wd.c: Change names of bootinfo fields. LINT: Nuke SYMTAB_SPACE. Fix comment about DODUMP. Makefile.i386: Nuke use of dbsym. Exclude gcc symbols from kernel unless compiling with -g. Remove unused macro. Fix comments and formatting. genassym.c: Generate defines for some new bootinfo fields. Change names of old ones. locore.s: Copy only the valid part of the `struct bootinfo' passed by the loader. Reserve space for symbol table, if any. machdep.c: Check the memory sizes passed by the loader, if any. Don't use them yet. bootinfo.h: Add a size field so that we can resolve some mismatches between the loader bootinfo and the kernel boot info. The version number is not so good for this because of historical botches and because it's harder to maintain. Add memory size and symbol table fields. Change the names of everything. Hacks to save a few bytes: asm.S, boot.c, boot2.S: Replace `ouraddr' by `(BOOTSEG << 4)'. boot.c: Don't statically initialize `loadflags' to 0. Disable the "REDUNDANT" code that skips the BIOS variables. Eliminate `total'. Combine some more printfs. boot.h, disk.c, io.c, table.c: Move all statically initialzed data to table.c. io.c: Don't put the A20 gate bits in a variable. Notes: svn path=/head/; revision=5908
