* vsprintf: Include stdarg for va_listMaxime Ripard2016-08-20-0/+2
| | | | | | | | | | | | vsprintf.h doesn't include the stdarg.h file, which means that it relies on the files that include vsprintf.h to include stdarg.h as well. Add an explicit include to avoid build errors when simply including that file.

* vsprintf.c: Always enable CONFIG_SYS_VSNPRINTFTom Rini2016-01-19-12/+0
| | | | | | | | | | | | | | Enabling this function always removes some class of string saftey issues. The size change here in general is about 400 bytes and this seems a reasonable trade-off.

* lib: Add function to extract a number from the end of a stringSimon Glass2015-07-21-0/+26
| | | | | | | Split out the code in fdtdec which finds a number at the end of a string. It can be useful in other situations. Signed-off-by: Simon Glass <sjg@chromium.org>
* mtd, nand: Move common functions from cmd_nand.c to common placeHeiko Schocher2015-06-30-0/+2
| | | | | | | | | | | | | | Move common functions from cmd_nand.c (for calculating offset and size from cmdline paramter) to common place, so they could used from other commands which use mtd partitions. For onenand the arg_off_size() is left in common/cmd_onenand.c. It should use now the common arg_off() function, but as I could not test onenand I let it there ...

* dm: Add a panic_str() function to reduce code sizeSimon Glass2015-04-23-0/+23
| | | | | | | | The printf() in panic() adds about 1.5KB of code size to SPL when compiled with Thumb-2. Provide a smaller version that does not support printf()-style arguments and use it in two commonly compiled places. Signed-off-by: Simon Glass <sjg@chromium.org>

* Add function to print a number with grouped digitsSimon Glass2013-06-26-0/+11
| | | | | | | Move bootstage's numbering printing code into a generic place so that it can be used by tracing also. Signed-off-by: Simon Glass <sjg@chromium.org>
* vsprintf: Move function documentation into header fileSimon Glass2011-12-17-0/+123
| | | | | | | Now that this is not in common.h, perhaps it is acceptable to move this documentation into the header file. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add safe vsnprintf and snprintf library functionsSonny Rao2011-12-17-0/+19
| | | | | | | | | | | | | | | | From: Sonny Rao <sonnyrao@chromium.org> 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.

* Move vsprintf functions into their own headerSimon Glass2011-12-17-0/+39
common.h is very large, so before changing the vsprintf functions, move the prototypes into their own header file. Signed-off-by: Simon Glass <sjg@chromium.org>
