malloc_simple: Add a little more debugging

2016-03-17T02:27:23+00:00

Output the pointer returned by each call to malloc(). This can be useful
when debugging memory problems.

malloc_simple: Add debug() information

2015-10-21T13:46:25+00:00

It's useful to get a a trace of memory allocations in early init. Add a
debug() call to provide that. It can be enabled by adding '#define DEBUG'
to the top of the file.

malloc_simple: Add Kconfig option for using only malloc_simple in the SPL

2015-10-20T16:40:27+00:00

common/dlmalloc.c is quite big, both in .text and .data usage, therefor
on some boards the SPL is build to use only malloc_simple.c and not the
dlmalloc.c code. This is done in various include/configs/foo.h with the
following construct:

 #ifdef CONFIG_SPL_BUILD
 #define CONFIG_SYS_MALLOC_SIMPLE
 #endif

This commit introduces a SPL_MALLOC_SIMPLE Kconfig bool which allows
selecting this functionality through Kconfig instead.

malloc_simple: fix malloc_ptr calculation

2015-09-28T14:15:48+00:00

The gd->malloc_ptr and the gd->malloc_limit are offsets to gd->malloc_base.
But the addr variable contains the absolute address. The new_ptr must be:
addr + bytes - gd->malloc_base.

malloc_simple: Correct the alignment logic in memalign_simple()

2015-08-28T16:33:14+00:00

This should use the align parameter, not bytes. Natural alignment is one
use case but should not be the only one supported by this function.

Add a simple version of memalign()

2015-06-11T01:26:55+00:00

This is used when the full malloc() is not available.

common: Make sure arch-specific map_sysmem() is defined

2015-04-18T17:11:09+00:00

In the case where the arch defines a custom map_sysmem(), make sure that
including just mapmem.h is sufficient to have these functions as they
are when the arch does not override it.

Also split the non-arch specific functions out of common.h

malloc_simple: Return NULL on malloc failure rather then calling panic()

2015-02-12T17:35:29+00:00

All callers of malloc should already do error checking, and may even be able
to continue without the alloc succeeding.

Moreover, common/malloc_simple.c is the only user of .rodata.str1.1 in
common/built-in.o when building the SPL, triggering this gcc bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303

Causing .rodata to grow with e.g. 0xc21 bytes, nullifying all benefits of
using malloc_simple in the first place.
