vsprintf:fix: Change type returned by ustrtoul

2012-12-13T18:46:02+00:00

The ustrtoul shall convert string defined size (e.g. 1GiB) to unsigned
long type (as its name implies).

Up till now it had returned int, which might cause problems with large
numbers (GiB range), when interpreted as U2 signed numbers.

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.

    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.
