* lib: Add obvious definition for `calloc`Tim Wawrzynczak2021-04-061-1/+11
| | | | | | | | | | | The calloc() function is useful in addition to malloc and friends, so add the obvious definition.

* lib/malloc: Implement a simple free() only for last malloc()Bora Guvendik2020-01-021-0/+29
| | | | | | | | | | | | | | | | Implement a free() that supports only the last malloc(). Rewind the heap to the last allocation point if the ptr to be freed is matching the end of heap before last malloc(). With current situation, since free() is no-op, every call to malloc() is a memory leak. BUG=b:140124451 TEST=Wrote a test function to do malloc and free operations.

* SMM: Add support for malloc in SMM if using TSEGDuncan Laurie2012-07-241-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | This is used by the SPI driver and ELOG. It requires SMM TSEG and a _heap/_eheap region defined in the linker script. The first time malloc is called in SMM the start and end pointers to the heap region will be relocated for the TSEG region. Enable SPI flash and ELOG in SMM and successfully allocate memory. The allocated addresses are verified to be sure they are within the TSEG heap region: smm.elf:00014000 B _eheap smm.elf:00010000 B _heap TSEG base is 0xad000000 Memory allocated in ELOG: ELOG: MEM @0xad018030 Change-Id: I5cca38e4888d597cbbfcd9983cd6a7ae3600c2a3 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1312 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

* Make memalign print useful messages on failureRonald G. Minnich2012-07-241-2/+9
| | | | | | | | | | | | | | | | | | Brevity is the soul of wit, except for error messages; then it's a sign of witlessness. I can say this because this error message may be my fault, although it is lost in the 20th century code base so who knows. Anyway, when memalign dies, it's not a bad idea to have a lot of information about what went wrong. So instead of the terse single bit of "something failed" this patch changes things to be a bit more useful. Change-Id: I8851502297e0ae9773912839ebfdf4f9574c8087 Signed-off-by: Ronald G.

* Debugging facility improvements.Uwe Hermann2010-11-101-3/+4
| | | | | | | | | | | | | | | | | | | - Hook up malloc() debug code via CONFIG_DEBUG_MALLOC. Only show it in menuconfig if at least DEBUG or SPEW are selected as loglevel, as this code does additional printk(BIOS_DEBUG, ...) calls which would otherwise not be visible anyway. - Similarly, make DEBUG_CAR and REALMODE_DEBUG only visible if thr DEBUG or SPEW loglevel is selected. - Get rid of a custom "debug" macro, use printk() as usual.
