At the moment the USB controller's pin muxing is not setup
correctly and causes a kernel panic upon system startup, so
disable the USB1 device tree node in the MPC5125 tower board
dts file.
The USB controller is connected to an USB3320 ULPI transceiver
and the device tree should receive an update to reflect correct
dependencies and required initialization data before the USB1
node can get re-enabled.

the 'soc' node in the MPC5125 "tower" board .dts has an '#interrupt-cells'
property although this node is not an interrupt controller
remove this erroneously placed property because starting with v3.13-rc1
lookup and resolution of 'interrupts' specs for peripherals gets misled
(tries to use the 'soc' as the interrupt parent which fails), emits
'no irq domain found' WARN() messages and breaks the boot process
[ best viewed with 'git diff -U5' to have DT node names in the context ]

dmatest fell out. Notably basic performance statistics, and
fixed / enhanced test control through new module parameters
'run', 'wait', 'noverify', and 'verbose'. Thanks to Andriy and

Commit c55aef0e5b ("powerpc/boot: Change the load address for the
wrapper to fit the kernel") adjusts the wrapper address unnecessarily
for platforms that use arch/powerpc/boot/of.c, since the code there
allocates space for the kernel wherever it can find it and doesn't
necessarily load the kernel at address 0. Changing the link address
is actually harmful since it can cause the zImage to overlap with
Open Firmware and thus fail to boot.
To fix this, we set make_space to n for all of the platforms that
use of.o.

Some CPUs (such as e500v1/v2) don't implement mftb and will take a
trap. mfspr should work on everything that has a timebase, and is the
preferred instruction according to ISA v2.06.
Currently we get away with mftb on 85xx because the assembler converts
it to mfspr due to -Wa,-me500. However, that flag has other effects
that are undesireable for certain targets (e.g. lwsync is converted to
sync), and is hostile to multiplatform kernels. Thus we would like to
stop setting it for all e500-family builds.
mftb/mftbu instances which are in 85xx code or common code are
converted. Instances which will never run on 85xx are left alone.

The Interlaken is a narrow, high speed channelized chip-to-chip interface. To

transaction-related transfers. Although based on the Interlaken protocol,
Interlaken Look-Aside is not directly compatible with Interlaken and can be
considered a different operation mode.
The Interlaken LA controller connects internal platform to Interlaken serial
interface. It accepts LA command through software portals, which are system
memory mapped 4KB spaces. The LA commands are then translated into the
Interlaken control words and data words, which are sent on TX side to TCAM
through SerDes lanes.
