8797b2cae3 sandbox: Add a new sandbox_spl board
It is useful to be able to build SPL for sandbox. It provides additional
build coverage and allows SPL features to be tested in sandbox. However
it does not need worthwhile to always create an SPL build. It nearly
doubles the build time and the feature is (so far) seldom used.

So for now, create a separate build target for sandbox SPL. This allows
experimentation with this new feature without impacting existing workflows.

19e8649e59 bootm: fixup silent Linux out of BOOTM_STATE_LOADOS state
The function fixup_silent_linux() is called in status BOOTM_STATE_LOADOS
to silence Linux if variable 'silent' is set.
Currently only the 'bootm' command state machine contains
BOOTM_STATE_LOADOS, but others like 'booti' or 'bootz' commands do not.
This means silent Linux does not work with these commands.

This patch moves the fixup_silent_linux() call out of the
BOOTM_STATE_LOADOS state and into BOOTM_STATE_OS_PREP, to silence Linux
independently of the used command (booti, bootm or bootz).

4b2fd720a7 stm32: Change USART port to USART6 for stm32f746 discovery board
This change is to remove a halt at about 200KiB
while sending a large(1MiB) binary to a micro controller using USART1.
USART1 is connected to a PC via an on-board ST-Link debugger
that also functions as a USB-Serial converter.
However, it seems to loss some data occasionally.
So I changed the serial port to USART6 and connected it to the PC using
an FTDI USB-Serial cable, therefore the transmission was successfully
completed.
