*	malloc_simple: Return NULL on malloc failure rather then calling panic()	Hans de Goede	2015-02-12	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	dm: Split the simple malloc() implementation into its own file	Simon Glass	2014-11-21	-0/+39
	The simple malloc() implementation is used when memory is tight. It provides a simple buffer with an incrementing pointer. At present the implementation is inside dlmalloc. Move it into its own file so that it is easier to find. Rather than using relocation as a signal that the full malloc() is available, add a special GD_FLG_FULL_MALLOC_INIT flag. This signals that the simple malloc() should no longer be used. In some cases, such as SPL, even the code space used by the full malloc() is wasteful. Add a CONFIG_SYS_MALLOC_SIMPLE option to provide only the simple malloc. In this case the full malloc is not available at all. It saves about 1KB of code space and about 0.5KB of data on Thumb 2.
