bbinfo.c module; news* boot blocks occupy all of the first 16 sectors,
with a jump instruction to skip the label at bytes 64..511.
Replace news_clearboot() and news_setboot() callbacks with common
news_copydisklable() callback, and set bbinfo_params->offset to
NEWS_BOOT_BLOCK_OFFSET (which is now 0), and ->headeroffset to 0.
(Thanks to Izumi for picking this up; the perils of working on code at 2am)
- bbinfo_params:
- replace "int littleendian" with "bbinfo_endian endian"
- add comments
- shared_bbinfo_clearboot():
- add callback method to shared_bbinfo_clearboot()
- don't clear from 0..headeroffset; use a callback to do that
- add news68k and newsmips support.
From Izumi Tsutsui <tsutsui@ceres.dti.ne.jp>, with a rework by me to
take advantage of the new shared_bbinfo_clearboot() callback.
(XXX: untested yet)
- unify sparc_bbinfo (1064 bytes, with 256 block entries)
and sun68k_bbinfo (296 byte, with 64 block entries)
into shared_bbinfo (512 bytes, with 118 block entries),
which will be also shared by future bbinfo-using platforms
(including macppc)
- add datestamp to *_BBINFO_MAGIC strings, to prevent installboot vs
bootxx version skew.
- add macppc support
*/bootxx.c:
- migrate to new shared_bbinfo structure
installboot:
- add macppc support (still needs applepartmap support and testing)
- improve and add some more warnings & errors to installboot
- implement shared_bbinfo_clearboot() and shared_bbinfo_setboot(), which
perform the majority of the work for bbinfo-using back-ends
(rather than replicating that across multiple back-ends).

and use instead of replicating the effort in various locations
- if filesystem is not a regular file, use sync(2) instead of fsync(2)
after the bootstrap has been written
- move <sys/stat.h> and <stdint.h> into "installboot.h"
- add `-B s2bno', to provide the starting block for the secondary bootstrap.
intended for use on platforms where the blocks of the stage2 bootstrap
are hardcoded into the stage1 bootstrap (currently: sparc, sun2)
- don't support `-b s1bno' for sparc or sun2, since the primary is always
at a fixed location on the disk.
- if `filesystem' is a regular file, use fsync(2) instead of sync(2)
code changes:
- add hardcode_stage2(), which uses -B s2bno and the size of the
provided secondary bootstrap (as an actual file, not as part of the
`filesystem' argument) to provide a sequential list of blocks from s2bno,
each block being the appropriate file system size (from
params->fstype->blocksize)
- add blocksize and needswap run-time parameters to ib_fs
- in *_match(), set params->fstype->blocksize to the underlying block size
(8KB for raw), and params->fstype->needswap as appropriate
- rename IB_STARTBLOCK to IB_STAGE1START, and add IB_STAGE2START
- use hardcode_stage2() to implement raw_findstage2() and IB_STAGE2BLOCK
support for ffs_findstage2()
- improve some comments, add some prototypes, ...
fstype checking, and back-end "ffs" support.
- Consistently use at least uint32_t for blocknumbers (vs. int / long / ...)
- Consistently use uintXX_t instead of u_intXX_t.
- Move various duplicated prototypes into "installboot.h"
existing backends, but future ones need it)
- use "bootstrap" instead of "boot block" in various messages where appropriate
- rename some members of ib_params
to use when they don't support a particular method
- don't automatically generate machines.c anymore
- add entries for i386 (temporarily unsupported) and shark
(permanently unsupported)
