Apply the following patch submitted by Evgeniy Ivanov:
http://mail-index.NetBSD.org/tech-kern/2011/12/15/msg012226.html
http://mail-index.NetBSD.org/tech-kern/2011/12/17/msg012229.html

- add 'ls' op to struct fs_ops to support ls command on each fs,
enabled by -DLIBSA_ENABLE_LS_OP and SAMISCMAKEFLAGS+="SA_ENABLE_LS_OP=yes"
in libsa
- split sys/lib/libsa/ufs_ls.c into UFS specific part and MI part (ls.c)
that opens the target fs and calls fs-depedent XXX_ls() functions
- add a ls op for ext2fs
(all other fs than ufs and ext2fs don't have actual ls ops yet)
- replace existing MD ufs_ls() calls with this new MI ls()

The original patch was written for i386 and ext2fs.
zaurus zboot has been tested by nonaka@.
ews4800mips and x68k loaders have been tested by me (with several fixes).
landisk might be okay since it was almost copied from i386.

XXX1: "ls" op in fs_ops looks a bit inconsistent, but we will be able to
replace it with real fs ops like readdir if it's really worth
XXX2: someone might have to check sys/arch/ia64/stand/efi/libefi/efifs_ls.c

MI libsa provides panic() and exit() functions, no need to provide our own.
As MI libsa exit() calls panic() with a "exit" message, don't use it if we
print our own farewell or have already panic()ed.

Fix 'boot -z' bogons.

Ansify function definitions w/o arguments. Generated with sed.

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

add a boot.cfg option to clear the screen; default off. From Anon Ymous

The structure of our elf kernel is:

elf header/program headers/text/data/note/
section headers/symbol table/string table

We need to read the section headers first to find the offset of the note
and thus we requite backwards seek. The only reason we need to read the
note is to find the version of the kernel, and this seems not to be used
anywhere. We could potentially change the kernel ldscript to add the note
information in the program headers, but dealing with ldscripts is painful
and producing a more complex binary could break some dumb standalone loader.
So the simple solution is to just disable the note loading for floppies
which is what this patch does. If someone wants to fix it in a better way,
be my guest.

Change the x86 boot blocks so they don't include builder login and date.

For now, we include kernel revision as a way of allowing users to
notice that boot blocks have gotten very old, so the first line of the
printout looks like this (depending on the particular block):

>> NetBSD/x86 BIOS Boot, Revision 3.4 (from NetBSD 5.0)

This may be changed a bit pending feedback. (Some people think that
the kernel revision shouldn't be there at all, for example.)

Part of the project to assure that bit-identical sources produce
bit-identical release binaries.

De-__P().

Consistently pass 'int *' arguments to parsebootfile.

Fix build breakage. Oops.

Fix signed/unsigned warnings.

sort boot flag to alphabetical order. add -c.

g/c COMPAT_OLDBOOT from bootblocks, sprinkle some const
bump bootblock version to 2.10

branches: 1.16.4;
update usage message (new flags -v, -q)

g/c RB_DFLTROOT

I've tried hard to find also various usage() messages and remove the
appropriate flag from there as well, hopefully all occurences are covered.

Do the same as biosboot does.
This makes it possible to create serial console dosboot.com's via uncommenting
the appropriate Makefile options.
I needed this when testing the SMP test kernels at work.

branches: 1.13.2;
remove bogus prototype for getopt

add prototypes, use ufs_ls() from mi libsa,
compile with -Wall -Wmissing-prototypes -Wstrict-prototypes -Wno-main

Don't give exit() a parameter, as libstand version doesn't take one.

../lib/exec_fromdos.c doesn't use the memory size returned by XMS check
anymore if other methods work better. Sync banner output with this.

-Don't try to parse the bootfile path in DOS mode.
-Take "dev" command from "biosboot" for consistency.

The additional linefeed appeared again... kill it.

Use common menu / parsing functions.
Adapt to new console / exec_netbsd arguments.

Use traditional memory detect function (int15/88) as indication for
a XMS driver.
From Martin Husemann.

branches: 1.5.2;
If we have xms print the xms memory size, and indicate that this is xms
memory in the banner. It is confusing to show 0 memory...

New welcome banner code, modeled after NetBSD/hp300's boot program
welcome banner code. Includes additional build information, and it
generally nicer to look at.

Remove strerror() prototype, it goes into stand.h.

Purely cosmetic whitespace/indentation changes (mmm, indent(1))
