* 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>
