drivers: bus: Match against id_table first ...

Matching against driver's name before looking throught its id_table
can lead to a somewhat strange and unintuitive behaviour where a
device whose driver's name matches one of the lines in id_table (which
is not unheard of in Linux kernel) will be probed against said driver
with 'id_table' field set to NULL which in turn will result in
dev_get_drvdata erroring out with -ENODEV.

This patch changes the behaviour such that device_match() only tries
to match against driver's name only if id_table of that driver is not
present.

ARM: pxa: pxa2xx use PSPR for resume address ...

Both lubbock and mainstone suspend to RAM were broken by the same
typo. The linux kernel saves the resume address to PSPR, ie. the scratch
pad register, while it was PSSR which was checked in barebox.

Fixing this typo was tested on mainstone where resume from S3 works.

net: smc1111: fix ethernet mac setting ...

Even if the setting of the MAC address does work correctly, the function
return an error.

In the former barebox version, this didn't seem to be a problem. In
v2015.11.0 version, the "ifup eth0" command fails because of this, and
as a consequence the network interface doesn't work.

The fix is straightforward.

ARM: Remove do_execute and thumb2_execute ...

In commit 104a6a7 support was added
for Thumb2.  It added do_execute() as a way to provide arch dependent
calling veneers for use in "go" and thumb2_execute() as the thumb2 to
arm veneer.

But thumb2_execute() isn't necessary as gcc generates a proper calling
sequence from a standard function pointer call.  Thumb2 barebox is
compiled with the AAPCS ABI which requires this.

It also had a bug and didn't pass the arguments properly, but code
execute via "go" rarely uses arguments so this wasn't very noticeable.

Since thumb2 was always the only user of do_execute(), go ahead and
delete that too.

ARM: Remove kernel booting call for thumb2 mode ...

The asm code to do the actual call into the kernel (or another
barebox) when compiled in thumb2 mode isn't necessary.  gcc generates
a perfectly good calling sequence from a normal function pointer call.
If it didn't, the code in bootstrap_boot() that uses a function
pointer to jump to the 2nd stage barebox from an xloader wouldn't
work.

It appears to be allowed that the call to kernel() could return, as
neither start_linux() nor kernel() are marked noreturn, and there is
code after calls to start_linux().

The asm code has a bug in this case, as it uses bx and not blx, and
thus doesn't set the link register.  Since it's a tail call, this
would be okay, but only if the LR value from the start of
start_linux() (and the callee-saved registers) are restored
beforehand, which isn't done.  The gcc generated call sequence will do
this.

Revert "memtest: move error handling to end of function" ...

While this simplifies the code as is I got the request to continue on

printed inline and not at the end of the function.

Use an 'initramfs' file if it exists instead of nfsroot. This offers the
possibility to quickly boot complete filesystems as initramfs without
the need to flash an SD-card or similar. If the initramfs does not

spi: i.MX: optimize transfers for ECSPI v2.3 ...

Instead of writing one word to the txfifo and then wait until
one is received in the rxfifo we can write while the txfifos
are not full and read as long the rxfifos contain data. This
makes transfers for the m25p80 driver around 7 times faster
here.

Unlike the last version this time we only optimize the common
case with 8 bits per word and SPI_LSB_FIRST cleared. The other
cases would require more bit shuffling of the data.

video: i.MX IPUv3: Set ldb clocks correctly ...

The clocks for the LVDS display bridge have a fixed /3.5 and a
configurable /1,/2 divider in their path. The configurable divider has
to be explicitly configured for single/dual channel support, so we can't
rely on clock rate parent propagation here. Clear the
CLK_SET_RATE_PARENT flag for the configurable divider and configure the
clock explicitly in the ldb driver.
Tested on a custom i.MX6 board, currently untested on i.MX53.
