f2863ff3f4 arm: imx: make bmode command work with SPL/U-Boot combo
The bmode command forces the SoC to use a specific boot device
by writing its boot mode into SRC_GPR9, and notifying the SoC of
the change using SRC_GPR10[28] bit: if the bit is on, bootROM
uses the value in SRC_GPR9 instead of SRC_SMBR1 to determine
the boot device.

SPL on the other hand is oblivious to this distinction, so once
the bootROM loads SPL from the device configured in SRC_GPR10,
SPL will attempt to load U-Boot from the device configured in
SRC_SMBR1, which is not updated by the bootROM to the value in
SRC_GPR9.

The result is that the selected boot device is not used across all
the boot stages.

Update spl_boot_device() to look at gpr9 when necessary.

0d8c7f747e ARM: UniPhier: decrease pre-reloc malloc area size
In the current implementation of the boot sequence of UniPhier
platform, 32KB temporary RAM is available before relocation.
The malloc area and the stack shares the 32KB area.

With CONFIG_SYS_MALLOC_F_LEN set to 0x7000 (28KB), only 0x1000 (4KB)
is left for the stack.  In some use cases, the system hangs up
with stack over-flow.

Even with driver-model UART enabled, the malloc area of 0x2000 (8KB)
should be enough.

7e78f7ad7f ppc4xx: Fix i2c repeated start
Debugging some i2c trouble I saw on my scope that repeated
start is not working properply. The 4xx even held clock pulled down
after transfers. Having a look in the driver I realized
that IIC_CNTL_RPST is set on that part of the transfer that should
begin with a repeated start. But repeated start is about not sending a
stop condition, so IIC_CNTL_RPST has to be set on the last transfer
before the repeated start happens.

2302b3ab85 hush: make run_command() return an error on parsing failure
run_command() returns success even if the command had a syntax error;
correct this behaviour.

128059b926 hush: fix segfault on syntax error
Hush segfaults if it sees a syntax error while attempting to parse a
command:

 $ ./u-boot -c "'"
 ...
 syntax error
 Segmentation fault (core dumped)

This is due to a NULL pointer dereference of in_str->p in static_peek().
The problem is that the exit condition for the loop in
parse_stream_outer() checks for rcode not being -1, but rcode is only
ever 0 or 1.

484408fb51 hush: return consistent codes from run_command()
Attempting to run:
 - an empty string
 - a string with just spaces

returns different error codes, 1 for the empty string and 0
for the string with just spaces.  Make both of them return
0 for consistency.

7dbcb76e77 sandbox: init cli for -c
sandbox crashes if a variable is set in the -c command, because
hush's top_vars is not allocated.  Call cli_init() from sandbox
to ensure this is done before we execute the -c command.

 $ ./u-boot -c 'a=1'
 ...
 Segmentation fault (core dumped)

854d2b9753 dlmalloc: ensure gd is set for early alloc
Attempting to run the sandbox leads to a segfault, because some dynamic
libraries (outside of u-boot) attempt to use malloc() to allocate memory
before u-boot's gd variable is initialized.

Check for gd not being NULL in the SYS_MALLOC_F_LEN handling, so that
malloc() doesn't crash when called at this point.

 $ gdb -q --args ./u-boot
 (gdb) r
