Hi All,

Sorry for the poor timing in bringing this up, but this just came up when discussing the review of some sunxi patches.

Ian asked me to add error handling for mmc_create failing, which, if used properly, only ever fails if calloc fails.

This made me thinking that we should switch u-boot to the glib memory alloc failure handling model, which is put a die() / abort() inside the low level malloc routines when they fail.

I remembered that I've already seen something like this in u-boot, so after some grepping around I've found that at least common/cli_hush.c already does this. It introduces a (private) xmalloc and xrealloc which have the malloc_or_die behavior.
