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
- use if() instead of #if
- adapt documentation to using CONFIG_SPL_SYS_MALLOC_F_LEN for
full-featured heap as well
- ensure SPL_CLEAR_BSS_F is set when using SYS_MALLOC_F_LEN for full
featured heap (or else, the heap status stored in bss will be overwritten
between board_init_f and board_init_r)
- fixed summary ("stack" -> "heap")
- enable CONFIG_SPL_CLEAR_BSS_F for socfpga_arria10 using full malloc
early in SPL

This introduces a new Kconfig option SPL_CLEAR_BSS_F. If enabled, it clears
the bss before calling board_init_f() instead of clearing it before calling
board_init_r().
This also ensures that variables placed in BSS can be shared between
board_init_f() and board_init_r() in SPL.
Make the new option depend on ARM for now until more implementations follow.

This implements the new option to clear BSS early in SPL for standard arm
and arm64 crt0.
BSS is cleared before calling board_init_f() and thus not cleared before
calling board_init_r() as it is not relocated in SPL.

If the malloc range passed to mem_malloc_init() is at the end of address
range and 'start + size' overflows to 0, following allocations fail as
mem_malloc_end is zero (which looks like uninitialized).
Fix this by subtracting 1 of 'start + size' overflows to zero.

Some platforms (like socfpga A10) need a big hep before SDRAM is available
(e.g. because FAT is used). For such platforms, simple_malloc is often not
a good option as it does not support freeing memory. These platforms often
use the non-Kconfig defines CONFIG_SYS_SPL_MALLOC_START (and its SIZE).
This patch allows enabling CONFIG_SPL_SYS_MALLOC_F_LEN while leaving
CONFIG_SPL_SYS_MALLOC_SIMPLE disabled. In this case, the full malloc heap
is made available as early as the simple_malloc heap would be normally.
This way, platforms can drop the non-Kconfig options to set up the full
heap and rely on the same automatically calculated heap allocation used
for simple heap.

Instead of fixing the SPL heap to 64 KiB in the board config header via
CONFIG_SYS_SPL_MALLOC_SIZE, let's just use CONFIG_SPL_SYS_MALLOC_F_LEN
in the defconfig.
This also has the advantage that it removes sub-mach specific ifdefs in
socfpga_common.h.

* [U-Boot] [PATCH v2 0/6] spl: full-featured heap cleanups

To: u-boot
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
