lib/vsprintf.c: don't special-case pointers to address null

2012-11-02T22:13:29+00:00

The %p format of printf() would print a pointer to address null as
"(null)".  This makes sense in a real OS where a NULL pointer must
never be dereferenced, but this is a bootloader, and there are cases
where accessing the data at address null makes perfect sense.

Remove the special case in lib/vsprintf.c using "#if 0" with a comment
to make clear this was an intentional change and to stop re-adding
this code.

lib: vsprintf.c: replace NUM_TYPE with s64/u64 types

2012-10-15T18:53:46+00:00

This fixes warnings when compiling with ELDK-5.2.1 for MIPS64:

vsprintf.c: In function 'put_dec':
vsprintf.c:258:9: warning: comparison of distinct pointer types lacks a cast [enabled by default]
vsprintf.c:258:3: warning: passing argument 1 of '__div64_32' from incompatible pointer type [enabled by default]
include/div64.h:22:17: note: expected 'uint64_t *' but argument is of type 'long long unsigned int *'

vsprintf: Move function documentation into header file

2011-12-17T22:34:01+00:00

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

Add safe vsnprintf and snprintf library functions

2011-12-17T22:33:20+00:00

From: Sonny Rao 

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.

(Simon Glass  modified this commit a little)

Move simple_itoa to vsprintf

2011-10-26T19:32:15+00:00

This function is generally useful and shouldn't hide away in hush. It
has been moved as is.

Add assert() for debug assertions

2011-09-09T22:04:01+00:00

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.

I see the following warnings:

for nearly all boards. This patch fixes this warning.

lib, vsprintf: introduce strict_strtoul

2011-05-12T19:07:06+00:00

as checkpatch proposes to use strict_strtoul instead of
simple_strtoul, introduce it.

Ported this function from Linux 2.6.38 commit ID:
