bootm: Print internal devicetree information without verbose ...

It's a precious information that barebox will boot the kernel
with the internal devicetree, so print it even in non verbose
mode.

of: populate devices based on "simple-bus" property ...

We used to populate the devices from the devicetree based on the
presence of the 'reg' property. This is incorrect since this only
allows us to probe devices with resources.
Instead use the 'simple-bus' property to see if we have iterate
deeper. This also registers devices with their buses as parents.

of: Call of_add_memory from of_probe ...

memory is always in /mem, so call of_add_memory from of_probe once
instead of in the recursive tree iteration. This makes it possible
to limit the device population to nodes with the "simple-bus" property
set.

of: When checking for existing devices also check resource end ...

When registering devices from the devicetree we check if these
devices already exist. When doing this not only check the resource
start but also the resource end.
This helps with the probing of simple buses for which child nodes
often begin at the very same address as the parents.

kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp ...

Based on the same Linux commit from Stephen Warren:

commit b40b25f
Author: Stephen Warren <swarren@nvidia.com>
Date:   Wed Mar 6 10:58:37 2013 -0700

    kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp

    Replace cmd_dtc with cmd_dtc_cpp, and delete the latter.

    Previously, a special file extension (.dtsp) was required to trigger
    the C pre-processor to run on device tree files. This was ugly. Now that
    previous changes have enhanced cmd_dtc_cpp to collect dependency
    information from both gcc -E and dtc, we can transparently run the pre-
    processor on all device tree files, irrespective of whether they
    use /include/ or #include syntax to include *.dtsi.

ARM: build dtbs during build process using extra-y ...

When using a builtin dtb the builtin dtb is built twice, once
from as a dependency of the 'dtbs' target and once as a dependency
of the corresponding dtb.o target. This can happen in parallel
with parallel make which results in build corruption when two
processes try to generate the dtb at the same time. Typical errors
include:

fixdep: error opening depfile: arch/arm/dts/.imx51-babbage.dtb.d: No such file or directory
make[1]: *** [arch/arm/dts/imx51-babbage.dtb] Error 2

fixdep: arch/arm/dts/.imx51-babbage.dtb.d is empty
mv: cannot stat `arch/arm/dts/.imx51-babbage.dtb.tmp': No such file or directory
make[1]: *** [arch/arm/dts/imx51-babbage.dtb] Error 1

To fix this build the devicetree blobs using extra-y instead of
a separate target.

ARM v7: fix mmu-off operation ...

Although conclusions in 50d1b2d "ARM
v7: Fix register corruption in v7_mmu_cache_off" are correct, the
implemented fix is not complete because the following failure can
happen:

1. d-cache contains the cache line around 'sp'

2. v7_mmu_cache_off() disables cache

3. early v7_mmu_cache_flush() pushes 'lr' on uncached stack

4. v7_mmu_cache_flush() flushes d-cache and can override stack written
   by step 3.

5. v7_mmu_cache_flush() pops 'lr' out of cache and jumps to it which
   might be random data now.

Patch avoids step 3 which is easy because 'lr' is never modified by the
function.  By using the 'r12' scratch register instead of 'r10', the
whole initial 'push' can be avoided.

Patch moves also the 'DMB' operation so that it is executed after data
has been pushed on stack.

net: dhcp: Fix tftp servername handling ...

When the dhcp code discovered the tftp-server-name option it immediately
tries to resolve the name. This can't succeed since the we are somewhere
in the dhcp processing and the nameserver may not even be known.

Fix this by resolving the name when dhcp is completed. While at it, do
this in a way that net_set_serverip is only called when resolv() returns
something useful. Otherwise we may end up overwriting a previously
configured serverip which came from the bootp bp_siaddr field.

MCI/MXS: fix signed/unsigned mismatch ...

Using the MXS MCI driver with an eight bit capable eMMC results into the
'devinfo' message the interface uses '0' bits for data transfer:

 barebox:/ devinfo mxs_mci0
 resources:
 num   : 0
 start : 0x80034000
 size  : 0x00002000
 driver: mxs_mci
 bus: platform

  Interface
   Min. bus clock: 1476 Hz
   Max. bus clock: 48000000 Hz
   Current bus clock: 24000000 Hz
   Bus width: 0 bit

The eight bit interface width is stored internally as value '2'. And a two bit
'2' ends up into 0xfffffffe when used as an array index. Using an unsigned
field instead fixes this issue:

 barebox:/ devinfo mxs_mci0
 resources:
 num   : 0

ARM i.MX31 pcm037: fix erroneous IOMUX GPR setup in pcm037_usb_init() ...

In commit ad09b59 "ARM i.MX31: give
register base addresses a proper MX31_ prefix", the IOMUX GPR setup
to enable USBH2 was replaced with an incorrect source register.
Instead of reading the GPR register, USBOTG HWHOST is used as rmw source,
which contains 0x10020001.
Beside the intended GPR[11] setup ("Enable USBH2 signals on AudioPort 3 and
AudioPort6"), this erroneously also sets
	GPR[28] enable USBOTG loopback
	GPR[17] override DSR_DCE1 with USBOTG_DATA4
	GPR[0]  select FIR DMA requests instead of UART2 DMA

Beside breaking UART2, it probably also broke some UART1 and USB OTG setups.
Fix this and replace the address with the appropriate defines.
