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.
Changes in v2: - make CONFIG_SPL_CLEAR_BSS_F depend on ARM for now - add CONFIG_SPL_CLEAR_BSS_F implementation for arm64 also
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
