ARM: imx6: add OF fixup to delete nonexistent CPU cores ...

Make sure that the DT passed to Linux reflects the actual number of CPU
cores present in the system by reading the SCU configuration. As both
the Q and DL variants of the MX6 have versions with cores fused away,
but the DTs have the maximum number of cores specified, this just deletes
any nonexistent CPU core nodes.

The baord type is autodetected based on the SoC type, so all boards

ARM: Allow compressed dtb binaries ...

In the current multi image build process the DTBs end up uncompressed
in the PBL. This can be annoying because the PBL is often very size
constrained.
This patch allows to put the DTBs in as lzo compressed binary into
the PBL. Since lzo offers quite good compression ratios for DTBs no
other compression algorithm has been implemented for now.
Boards which want to use the compressed DTBs only have to change
the __dtb_ prefix in the DTB name to __dtb_z_. Also they should select
ARM_USE_COMPRESSED_DTB to make sure barebox supports uncompressing
the DTB.

usb: core: drop unnecessary le16_to_cpu() conversion ...

In drivers/usb/core/usb.c we already have le16_to_cpus() conversion
just after usb_get_descriptor():

    390     /* correct le values */
    391     le16_to_cpus(&dev->descriptor->bcdUSB);
    392     le16_to_cpus(&dev->descriptor->idVendor);
    393     le16_to_cpus(&dev->descriptor->idProduct);
    394     le16_to_cpus(&dev->descriptor->bcdDevice);

so no additional idVendor/idProduct descriptor fields
le16_to_cpu() conversion is needed after that.

On the big-endian machines extra le16_to_cpu() conversion
leads to wrong idVendor/idProduct USB device parameters values
(e.g. see devinfo <usb-device> output), and to a much more
serious problem: idVendor/idProduct-based USB device detection
does not work.

commands: ls: use 14 digits for filesize ...

10 digits are not enough for modern SATA/USB storages. E.g.:

    barebox> ls -l /dev/
    cr-------- 500107862016 ata0
    cr--------   33554432 ata0.0
    cr-------- 500073258496 ata0.1

    cr--------   67108864 disk0.0
    cr-------- 32156680192 disk0.1

14 digits look much better. E.g.:

    barebox> ls -l /dev/
    cr--------   500107862016 ata0
    cr--------       33554432 ata0.0

xload: be more flexible when searching for second stage bootloader. ...

A first stage bootloader can read fat and ext4 filesystems, and
even both can be compiled-in at the same time.
But then xload has a hardcoded fat filesystem mount option which
renders ext4 unusable.
This patch tries to mount it as ext4 if the fat attempt fails.

Then, a typical use case of an ext4 formatted filesystem
is it to be a standard linux filesystem, which contains
boot-related files in /boot. So, when searching for the second stage
bootloader, try /boot/barebox.bin after not finding it in /barebox.bin

at91sam9x5: fix ROM base address (bugfix for nand ECC)i ...

The ROM base address in the 9x5 processors lives at 1M, not 4M,
where SMD is, as defined later in the same file.

The ROM includes some tables that are used to build error-correction data
for NAND memory.  By using the wrong address, we get wrong data and
the result is undetected bit flips (data at 0x408000 is all zeroes).

Thus, even though our kernel was fixing bit errors in NAND, barebox
was not fixing them. With UBI (our situation) we got I/O errors because
the checksum verification for data nodes failed.

Using the proper address corrects the problem: barebox reports a
"bitflip" message, consistent with the kernel message for the same
file, and the files are properly loaded and booted.

Note: the kernel has the same wrong define, but then the magic number
0x00108000 as spelled in arch/arm/boot/dts/at91sam9x5.dtsi is used
instead of the symbolic name.
