[U-Boot] [PATCH 0/6] spl: full-featured heap cleanups

[Simon Goldschmidt]

Some platforms cannot use simple malloc even in very early stages, e.g.
when using FAT before DRAM is available. Such platforms currently often
use non-Kconfig defines to initialize full malloc and rely on simple heap
before that.

This series makes some adjustments to ensure SPL behaves the same with
simple or full malloc: when CONFIG_SPL_SYS_MALLOC_F_LEN is != 0, both heap
types can be used (by changing CONFIG_SPL_SYS_MALLOC_SIMPLE), without
manually supplying an address range for the full heap.


Simon Goldschmidt (6):
  spl: add Kconfig option to clear bss early
  spl: arm: implement SPL_CLEAR_BSS_F
  dlmalloc: fix malloc range at end of ram
  dlmalloc: be compatible to tiny printf
  spl: support using full malloc with SYS_MALLOC_F_LEN
  arm: socfpga: a10: move SPL stack size to Kconfig
