arm: socfpga: mailbox: Fix off-by-one error on command length checking
A mailbox command contains 1-u32 header + arguments. The "len" variable
only contains the length of the arguments, but not the 1-u32 header.
Include the length of header when checking the ring buffer space to
prevent off-by-one error.

- added (this) patch with further cleanups to the socfpga board config
files
socfpga_common.h defines CONFIG_SYS_BOOTMAPSZ to 64 MiB.
Since having this define overrides the 'bootm_size' env variable for
the whole socfpga platform, let's remove this define from socfpga_common.h
and instead rely on the 'bootm_size' env variable (which is initialized
to 160 MiB in the same file's default env). This gives users the
chance to override it in their own environment.

- added (this) patch to move socfpga_vining to DM_I2C
By enabling debug prints in malloc_simple, we can see that SPL for socfpga
gen5 does by far not need the 8 KiB malloc pool currently allocated for
SPL in pre-reloc phase.
On socfpga_socrates, 1304 bytes are currently used (and this increases by
~200 bytes only for the sdram/reset fixes in socfpga-next).
To prevent wasting precious SRAM space, let's reduce the initial heap used
for SPL to 2 KiB. This is still some hundred bytes more than currently
used. Also, the gen5 SPL enables stack and heap in DDR memory pretty
early. Only the initial uclass/dm parsing, serial console and DDR
initialization is done in the initial heap, so these 2 KiB should be
enough for all boards.

If SPL post-reloc stage puts the stack into DDR, U-Boot should be able to
do that, too.
The reason to do so is that this way, U-Boot initial stack can be larger
than SPL initial stack. In situations where we want to save the SPL
in SRAM for next boot without reloading, this prevents overwriting the
SPL DTB in SRAM if U-Boot stack usage gets too high.
To achieve this, the malloc definition for a10 is moved up and sligthly
changed to ensure CONFIG_SYS_INIT_RAM_SIZE is the remaining available size.

This patch makes the on-board RTC work on the socfpga_socrates board.
This rtc is present on the board, but it does not work (fails with a
timeout).
This patch adds a weak pull-up on the I2C0-SCL pin connected to the m41t82
RTC on this board. While the SDA line has a pull-up on the pcb, the pull-up
on the SCL line seems to be missing. To work around this, enable the
weak-pull-up feature on this pin.
After applying this patch, the rtc timeout is gone and the 'date' command

This adds a compatible string for m41t82. This ensures that this driver

Using this driver on socfpga gen5 with DM_I2C enabled leads to a data abort
