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
errors in memtest, which can be better implemented when the messages are
printed inline and not at the end of the function.

This reverts commit 4ff9e28.

mtd: core: initialize *retlen in mtd_write() ...

Some mtd drivers like the spi-nor driver do not assign a value
to the retlen pointer but instead only add the bytes written
to *retlen. Users of mtd_write expect the variable to be initialized
by the mtd core though, so we have to do it in mtd_write(). The
same is done in mtd_read already.

'putchar' is a standard function to output a character. Use this one
instead of the lower level console_putc.

loadb: Use local cdev ...

We already retrieve a console_device using console_get_first_active().
Use this one also to send/receive characters instead of the combined
input/output of all console devices with putc/getc.

well.

ARM: Fix bug in remap_range ...

remap_range takes generic MAP_CACHED/MAP_UNCACHED flags which are then
translated into the corresponding ARM specific bits. We call remap_range
internally from dma_alloc_* aswell, but instead of passing the generic
flags we pass the ARM specific bits.
Fix this by creating an internal __remap_range function which takes the
ARM specific bits and use it where appropriate.

usb: mx25: fix bit position of "Host power mask" ...

The bit MX25_H1_PM_BIT value is handled for port 1 as MX25_OTG_PM_BIT is
for port 0. The latter is called "OPM: OTG power mask" in the i.MX25
reference manual. Its description matches the description of "HPM: Host
power mask" for the host port which is bit 16, not 8.

The Linux kernel (as of 4.3) also has

	#define MX25_H1_PM_BIT                  BIT(16)

fs: smhfs: Fix return value of truncate() ...

Returning -ENOSYS as a result of truncate() breaks ability to write to
semihosting host's filesystem, so change the return value to 0. This
shouldn't cause any problems since all of the funcionlaity of
truncate() should is already handled by 'open' (via O_TRUNC) and
'write' (will automatically grow the file size when writing)
automatically

Unfortunately this was missed in original commit that introduced
semihosting
