ubifs: Fix reading holes in files ...

When a whole block of 4KiB in an ubifs file is zero then the block is
not stored in the filesystem. read_block() returns -ENOENT in this case,
so this return value must be treated as success.

arm: imx53-guf-vincell-lt: dts: do not specfiy fixed memory information ...

Setting a fixed memory size prevents from using the different board
variants with different memories equipped.

barebox is able to read RAM size informations from the imx53 RAM
controller and thus does not require this information passed via dts.

ARM: PXA: move HAVE_CLK select ...

Claiming that all of PXA has CLK implemented, while only PXA3XX
selects the relevant clock implementations causes lots of build
failures for the other PXA architectures.

Fix it by moving the HAVE_CLK select to the one PXA arch, that
actually has it.

This patch moves the error message about missing crypto support so that the
used crypto algo is printed. Without this patch the algo is always shown as a
NULL pointer.

imx233-olinuxino: Fix mx23_power_init() arguments ...

Commit 4d70da6 ("ARM: MXS: power-init: Add parameters to
mx28_power_init()") causes imx233-olinuxino to not boot anymore.

imx233-olinuxino is commonly powered from external input supply,
so adjust the mx23_power_init() arguments to reflect that.

reset: fix non GPIO reset ...

The reset controller structure is zero initialized in the OF
reset case, but as 0 is also a valid GPIO number the current
code tries to assert/deassert the GPIO instead of calling into
the reset controller device.

PCI: imx6: properly shut down core when leaving barebox ...

As the i.MX6 PCIe core doesn't have a software reachable reset
wired up, it's hard for any driver to get the core into a known
good state.

To make it easier for whatever software follows barebox, bring
back the core into a safe state before leaving barebox.

i.MX6: pci: Avoid aborts when asserting PCIe reset ...

When booting Barebox in the HW environment where PCIe core has been
used but not properly shut down, writing to PCIE_PL_PFLR in
imx6_pcie_assert_core_reset would cause data abort exception.

The problem can be easily reproduced on a i.MX6 based board with PCIe
slot populated with some device by doing:

> bootm -f -e 0x1050 <your board's>.img

Ignoring this exception seem to allow PCIe core to successfully
initialize and enumerate devices properly. This is also how Linux
Kernel version of the driver handles this situation -- it installs
dummy no-op abort handler at the beginning of device's probing.

of_path: Drop possible further extensions of device-path property ...

Originally it was intended to further extend the multi string property
device-path further with more elements, like for example a filename. It
turned out though that this is too complex and instead of further
extending the property we should instead create additional properties,
so this mechanism is removed with this patch to make the code simpler.
