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.

You should probably depend this option on "ARM", as your implementation
is currently only for this arch. Otherwise users might expect this to
work on other platforms as well.

Hmm, ok. I thought it might be worth leaving this visible for everyone.
But you're right that people migh rely on this to work where it's not
implemented...
I'll add that dependency in v2.

This implements the new option to clear BSS early in SPL for standard arm
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.

Hi Simon,
you were replying to v1 where v2 has already been sent. However, this
patch hasn't changed, so I'm commenting here.

Yes, you're right. Honestly, I didn't want to go through all the
documentation mess unless getting at least some slightly positive
feedback to this. Searching the readme files and Kconfig help to get
them consistent is probably more work than coding these patches :-)

Instead of fixing the SPL stack 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 advandage that it removes sub-mach specific ifdefs in
socfpga_common.h.

This patch was part of an socfpga series before. It didn't work there and
was the reason for this series. It also serves as a demonstration of this
series.
