boards that use u-boot. A known board database lists boards and their
respective u-boot packages. u-boot packages are discovered at run-time
(in /usr/pkg/share/u-boot, by default). These packages contain board
database overlays that describe u-boot installation procedure that's
specific for that board.
Support this as a native tool and as a host tool. The native tool
will attempt to determine the running board type using OpenFirmware
calls. Host tool and native tool alike may also specify a board type
directly using the "-o board=xxx option" or have installboot(8) determine
the board type from a device tree blob using "-o dtb=/path/to/board.dtb".
A "-o media=xxx" option is provided for boards that have different u-boot
binaries and/or installation procedures for different media types (e.g.
SDMMC, eMMC, or USB).
This is trivial to extend to other evb* platforms that use u-boot, even if
they don't use FDT for autoconfiguration.
Add a sanity check of the disk_buf first three bytes. The original code on
a disk with nul bytes was causing integer overflow and thus calling the
memcmp(3) functin in is_zero() with enormous length.
Verity that the 0th byte is JMP, 1th a signed byte >=9 to prevent overflow
and 2th byte NOP.
Add a comment explaining the check.
Detected with MKSANITIZER and ASan.
to gcc-4.8 for discovering the bug and to Atari for having a LABELOFFSET of
516 > 512 :-)
XXX: Perhaps we should put all those constants in <sys/bootblock.h> instead
of spreading them around.
by Jonny Billquist, thanks to Marl Pizzolato for patiently explaining
the various ways of booting a vax to me.
Now VAX 780 can boot directly from VMB.EXE again.
NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the
Giano system simulator.
eMIPS is a platform developed at Microsoft Research for researching
reconfigurable computing. eMIPS allows dynamic loading and scheduling
of application-specific circuits for the purpose of accelerating
computations based on the current workload.
NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research
by Alessandro Forin and Neil Pittman. Microsoft Corporation has
donated full copyright to The NetBSD Foundation.
Platform support for eMIPS is the first part of Microsoft's
contribution. The second part includes the hardware accelerator
framework and will be proposed on tech-kern soon.
LOADMODULES->NOMODULES and READBOOTCONF->NOBOOTCONF.
This way, the default value (0) wired into old bootxx_* and installed
to file systems remains valid and we avoid problems on partial updates.
whether modules are loaded and whether boot.cfg is evaluated, and
set both to "off" per default in the PXE bootloader.
Extend "installboot" to toggle the bits.
This way, pxeboot works with existing dhcp server setups (and as
described in the manpage) out of the box. Also, boot.cfg reading
involves a stat() call which is horribly inefficient with the
TFTP pseudo file system.
where sector size (disk block size) is required, instead of
DEV_BSIZE constant which means device I/O block size.
"Looks reasonable" from dholland@, and fixes tools installboot(8)
on Cygwin where DEV_BSIZE != 512 as mentioned in PR toolchain/42555.
If specified then checks on the disks BPB are not done, and any existing BPB
is deleted.
This is needed soince newfs(8) doesn't overwrite the BPB - which is basically
the FAT superblock.
Update documentation and add an example of using bootxx_fat16.
Automatically enable writes to the 'labelsector' if necessary.
Detect and recover from problems with the write-protected 'labelsector'
stopping writes to nearby sectors when the non-raw disk device is used.
Support the installation of 512-byte pbr boot code (eg fatboot).
Verify that there is enough reserved space in the bpb (if not all zeros) to
avoid overwriting the start of FAT filesystems.
