Makefile: Speed up evaluation of ld options ...

Since "333ff7b1e4 Fix linking with new ld, based on u-boot" the build
with multiple images became unreasonable slow. This is because the
ld-option macro was evaluated once for each image. Fix this by exporting
and using LDFLAGS_barebox from the main Makefile.

usb: imx: Only use clock when it exists ...

Fixes: bbe0df9

I assumed all chipidea devices actually have a clock. This is true
when looking at the device tree, but in barebox not all i.MX SoCs
use the clocks provided by the device tree. Most instead use
clkdev_add_physbase() to attach a clocks to devices. For these the
chipidea device does not have a clock.

globalvar: Fix value of new globalvar when nvvar exists ...

When a new globalvar with a value is created and the corresponding
nvvar exists, then the globalvar gets the value of the nvvar, not
from the newly assigned value as expected.

nv quux=foo; global quux=bar; echo ${global.quux}

Should give "bar", not "foo". Fix this.

clock: initialize dummy clocksource statically ...

Assigning the dummy clocksource in a initcall has the problem that
get_time_ns() crashes before that initcall is executed. This happens
when dmesg support is enabled in conjunction with CONFIG_DEBUG_INITCALLS.
In this case the dmesg code wants to have the timestamp of a log
message.
Solve this by setting the current clocksource to the dummy clock
statically and not at runtime. This way we always have a dummy
clock available.

In backend_format_raw_pack() digest_length is used before it's

state: Fix "pack" returning freed data for DTB backend ...

`state_backend_format_dtb_pack()` passes a buffer containing state
packed in flattened DTB format back to its caller via its `buf`
parameter.  It then frees the buffer before returning.  This means the
caller (`state_save()`) will be working on freed buffer contents before
freeing the buffer a second time itself.  Fix it by removing the
spurious call to `free()`.

This should fix a bug reported by Norbert Wiedmann in
<http://lists.infradead.org/pipermail/barebox/2017-April/029980.html>.

ARM: cache-l2x0: honour aux_val when determing way size ...

l2x0_init() allows to overwrite bits in the AUX_CTRL register
using the aux_val/aux_mask arguments. On i.MX35 this is used
to pass a correct AUX_CTRL value to overwrite bogus reset values
for this register. To make this work we have to apply
aux_val/aux_mask before using the AUX_CTRL value to determine the
way size.

Before this commit the way size was hardcoded to 8.

Set needs_refresh back to 0 after refreshing so that we do not refresh

mtd: nand_omap_gpmc: fix BCH error correction ...

BCH error detection and correction was only looking at the first
of four syndrome polynomials, which meant it was failing to detect
and correct bitflips in the last 3/4 of the data. In effect, only
the first 512 bytes of a 2048 byte page were being protected by ECC.

The syndrome polynomials (BCH error codes) are stored in the NAND's
OOB, each of which protects 512 bytes of data. The driver used
eccsteps = 1 which effectively made it only use the first polynomial,
and therefore was only protecting the first 512 bytes of the page.

The fix is to pull over a bit of code from the kernel's
omap_correct_data() that sets eccsteps = 4 when the page size is 2048
bytes and hardware ECC is being used.
