This fixes warnings when compiling with ELDK-5.2.1 for MIPS64:
vsprintf.c: In function 'put_dec':

Now that this is not in common.h, perhaps it is acceptable to move this
documentation into the header file.

These functions are useful in U-Boot because they allow a graceful failure
rather than an unpredictable stack overflow when printf() buffers are
exceeded.
Mostly copied from the Linux kernel. I copied vscnprintf and
scnprintf so we can change printf and vprintf to use the safe
implementation but still return the correct values.

assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined.
This is useful when a condition is an error but a board reset is unlikely
to fix it, so it is better to soldier on in hope. Assertion failures should
be caught during development/test.
It turns out that assert() is defined separately in a few places in U-Boot
with various meanings. This patch cleans up some of these.
Build errors exposed by this change (and defining DEBUG) are also fixed in
this patch.

panic: add noreturn attribute
I see the following warnings:
vsprintf.c: In function 'panic':
vsprintf.c:730: warning: 'noreturn' function does return
for nearly all boards. This patch fixes this warning.

The duplication of the do_reset prototype has gotten out of hand,
and they're not all in sync. Unify them all in command.h.

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".
This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:
int main (int argc, char **argv)
{
while (--argc > 0 && **++argv == '-') {
/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}
The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'
N.B.: The code above can be trivially rewritten like this:
while (--argc > 0 && **++argv == '-') {
char *arg = *argv;
while (*++arg) {
switch (*arg) {
...

Now that the other architecture-specific lib directories have been
moved out of the top-level directory there's not much reason to have the

There is more and more usage of printing 64bit values,
so enable this feature generally, and delete the

Use do_div from div64.h for vsprintf in case of 64bit division.
For 32bit division, do_div from div64.h can't be used as it
needs a 64bit parameter.

This brings in support for the %p modifier which allows us to easily print
out things like ip addresses, mac addresses, and pointers.
It also converts the rarely used 'q' length modifier to the common 'L'
modifier when dealing with quad types.
While this new code is a bit larger (~1k .text), most of it should be made
up by converting the existing ip/mac address code to use format modifiers.

This patch adds basic UBI (Unsorted Block Image) support to U-Boot.
It's based on the Linux UBI version and basically has a "OS"
translation wrapper that defines most Linux specific calls
(spin_lock() etc.) into no-ops. Some source code parts have been
uncommented by "#ifdef UBI_LINUX". This makes it easier to compare
this version with the Linux version and simplifies future UBI
ports/bug-fixes from the Linux version.

* Patch by Masami Komiya, 27 Feb 2004:
Fix rarpboot: add autoload by NFS
* Patch by Dan Eisenhut, 26 Feb 2004:
fix flash_write return value in saveenv
* Patch by Stephan Linz, 11 Dec 2003
expand config.mk to avoid trigraph warnings on NIOS
* Rename "BMS2003" board into "HMI10"
- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)
- Hymod board database mods: add "who" field and new xilinx chip types
- provide new "init_cmd_timeout()" function so code external to
"common/main.c" can use the "reset_cmd_timeout()" function before
entering the main loop
- add DTT support for adm1021 (new file dtt/adm1021.c; config
slightly different. see include/configs/hymod.h for an example
(requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
CFG_DTT_ADM1021 defined)
- add new "eeprom_probe()" function which has similar args and
behaves in a similar way to "eeprom_read()" etc.
- add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
- gdbtools copyright update
- ensure that set_msr() executes the "sync" and "isync" instructions
after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
- 8260 I/O ports fix: Open Drain should be set last when configuring
- add SIU IRQ defines for 8260
- allow LDSCRIPT override and OBJCFLAGS initialization: change to
config.mk to allow board configurations to override the GNU
linker script, selected via the LDSCRIPT, make variable, and to
give an initial value to the OBJCFLAGS make variable
- 8260 i2c enhancement:
o correctly extends the timeout depending on the size of all
queued messages for both transmit and receive
o will not continue with receive if transmit times out
o ensures that the error callback is done for all queued tx
and rx messages
o correctly detects both tx and rx timeouts, only delivers one to
the callback, and does not overwrite an earlier error
o logic in i2c_probe now correct
- add "vprintf()" function so that "panic()" function can be
technically correct
- many Hymod board changes
