This allow for convenient use of QEMU machine to test loading of UBI
filesystem. There are a couple of changes made together of this which
are required:

 1) The malloc must be at least 512 KiB to allow the use of UBI
    filesystem. We are going to enable it in a next patch.

 2) MTD_DEVICE must be enabled, otherwise we get missing symbols
    during the build

Following configs were change:

 - vexpress_aemv8a_dram_defconfig
 - vexpress_aemv8a_juno_defconfig
 - vexpress_aemv8a_semi_defconfig
 - vexpress_ca15_tc2_defconfig

When the spi_flash_probe_bus_cs() was previously called, it was
called using 0's for two values where CONFIG_ENV_SPI_MAX_HZ and
CONFIG_ENV_SPI_MODE are now used.  When changed this
caused the environment to fail the CRC check and the default
was used.  This patch defines both of these values back 0.

Recent removal of obsolete partition led to shifting of starting address
of "reserved" partition (which reflects U-Boot environment). Fix its
start address to keep it in sync with ENV_OFFSET and DFU environment.

This patch also provides fixed start address for "reserved" partition,
so that we can track when it's shifted next time.

While at it, move it before "misc" partition to keep all Android

Based on the MCU R5 efuse settings, R5F cores in MCU domain
either work in split mode or in lock step mode.

If efuse settings are in lockstep mode: ROM release R5 cores
and SPL continues to run on the R5 core is lockstep mode.

If efuse settings are in split mode: ROM releases both the R5
cores simultaneously and allow SPL to run on both the cores.
In this case it is bootloader's responsibility to detect core
1 and park it. Else both the core will be running bootloader
independently which might result in an unexpected behaviour.

- Bring in the series from Simon for SPL logging support and bloblist

There is some basic informaton that SPL normally wants to pass through to
U-Boot, such as the SDRAM size and bank information.

Mkae use of the new bloblist structure for this. Add a new 'handoff' blob
which is set up in SPL and passed to U-Boot proper. Also adda  test for
sandbox_spl that checks that this works correctly and a new 'sb' command
to show the information passed from SPL.

Most architectures use jump_to_image_no_args() to jump from SPL to U-Boot.
At present sandbox is special in that it jumps in its
spl_board_load_image() call. This is not strictly correct, and means that
sandbox misses out some parts of board_init_r(), just as calling
bloblist_finish(), for example.

Change spl_board_load_image() to just identify the filename to boot, and
implement jump_to_image_no_args() to actually jump to it.

The current method of starting U-Boot from U-Boot adds arguments to pass
the memory file through, so that memory is preserved. This is fine for a
single call, but if we call from TPL -> SPL -> U-Boot the arguments build
up and we have several memory files in the argument list.

Adjust the implementation to filter out arguments that we want to replace
with new ones. Also print a useful error if the exec() call fails.

At present sandbox calls malloc() from various places in the OS layer and
this results in calls to U-Boot's malloc() implementation. It is better to
use the on in the OS layer, since it does not mix allocations with the
main U-Boot code.

Fix this by replacing calls with malloc() to os_malloc(), etc.

At present os_jump_to_image() jumps to a given image, and this is written
to a file. But it is useful to be able to jump to a file also.

To avoid duplicating code, split out the implementation of
os_jump_to_image() into a new function that jumps to a file.

We support putc() in this case but not puts(), but this is more useful
since it is what printf() uses.

This particularly affects debugging early in SPL, where currently printf()
statements result in no output. Fix this by adding a special case into
puts() for sandbox, just like putc().

We should use a macro rather than hard-coding the SPL prompt to 'spl'
since the code can be used by TPL too. Add a macro that works for both
and use it in various places.

This allows TPL to use the same code without printing confusing messages.

Note that the string is lower case ('spl', 'tpl') which is a change from
previously.
