The NAND Flash environment consists of several distinct components:
- NAND framework (drivers harness for NAND controllers and NAND chips)
- NAND simulator (NANDsim)
- NAND file system (NAND FS)
- Companion tools and utilities
- Documentation (manual pages)
This work is still experimental. Please use with caution.

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.
This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.
As I looked through the C library, I noticed the FreeBSD MIPS port has a
hand-written version of index(). This is nice, if it weren't for the
fact that most applications call strchr() instead.
Also, on the other architectures index() and strchr() are identical,
meaning we have two identical pieces of code in the C library and
statically linked applications.
Solve this by naming the actual file strchr.[cS] and let it use
__strong_reference()/STRONG_ALIAS() to provide the index() routine. Do
the same for rindex()/strrchr().
This seems to make the C libraries and static binaries slightly smaller,
but this reduction in size seems negligible.
At work we have a single tftp server that provides installation data for
a variety of operating systems. I'd rather place our FreeBSD-related
files in a subdirectory, instead of the root.
It would be nice if this setting could be run-time configurable, but at
least in our specific case, this is not possible, as pxeboot is
chainloaded through pxelinux.

In C90, NULL is guaranteed to be declared in <stddef.h> and also in
<string.h>. Though the correct way to define NULL in FreeBSD is to
include <sys/_null.h>, other parts of libstand still require <string.h>
to build; therefore, we keep <string.h> in stand.h and add a note about
this;
- Removing no longer used 'Prototype' definition. Quote from bde@:
'Cruft related to getting incomplete struct declarations within
prototypes forward-declared before the structs. It doesn't mean
"prototype" but only part of a prototype-related hack. No longer
used.'
- Replacing iaddr_t with uintptr_t;
- Removing use of long double to determine alignment. Use a fixed 16 byte
alignment instead;

this fix only applies to zalloc.c, the other part of libstand such like
qdivrem.c still gives compilation warnings on sparc64 tinderbox builds;
therefore, WARNS level isn't changed for now.

(1) Coding style changes.
(2) If the server does not acknowledge any blocksize option,
revert to the default blocksize of 512 bytes.
(3) Send ACK if the first packet happens to be the last packet.
(4) Do not accept blocksize greater than what was requested.
(5) Drop any unwanted OACK received if a tftp transfer is already
in progress.
(6) Terminate incomplete transfers with a special no-error ERROR packet.
Otherwise we rely on the tftp server to time out, which it does
eventually, after re-sending the last packet several times and spamming
the system log about it every time. This idea is borrowed from the
PXE client, which does exactly that.

- Given that we tell the compiler that struct ip is packed and 32-bit
aligned, GCC 4.2.1 also generates code for sendudp() that assumes
this alignment. GCC 4.2.1 however doesn't 32-bit align wbuf, causing
the loader to crash due to an unaligned access of wbuf in sendudp()
when netbooting sparc64. Solve this by specifying wbuf as packed and
32-bit aligned, too. As for lastdata and readudp() this currently is
no issue when compiled with GCC 4.2.1, though give lastdata the same
treatment as wbuf for consistency and possibility of being affected
in the future. [1]

send along the "blksize" option specified in RFC2348,
and the "tsize" option specified in RFC2349.
Add code to parse the TFTP Option Acknowledgement (OACK) packet as
specified in RFC2347.
For TFTP servers which support the "blksize" option, we can
specify a TFTP Data block size larger than the default 512 bytes
specified in RFC1350. This offers greater read performance when
downloading files.
We request an initial size of 1428 bytes, which is less than the
Ethernet MTU of 1500 bytes. If the TFTP server sends back an OACK
packet, then use the block size specified in the OACK packet.
Most times it is usually the same value as what we request.
If the TFTP server supports RFC2348, we will see performance improvements
by transferring files over TFTP with larger block sizes.
If we do not get back an OACK packet, then we most likely we
are interoperating with a legacy TFTP server that does not
support TFTP extension options, so default to the block size of
512 bytes.
(2) If the "tftp.blksize" environment variable is set, then
take that value and use it when sending the TFTP RRQ packet,
instead of 1428. This allows us to set different values of
"tftp.blksize" in the loader, so that we can test out different
TFTP block sizes at run time.

This allows the nfs_getrootfh() function to return the
correct file handle size to pxe.c for pxeboot. It also
results in NFSv2 no longer being used by default anywhere
in FreeBSD. If built with OLD_NFSV2 defined, the old
code that predated this patch will be built and NFSv2
will be used.
