Note that this patch affects qemuarm AND qemuarm64.
When booting a VM and during operation, the following message
periodically appears:
INIT: Id "hvc0" respawning too fast: disabled for 5 minutes
This is because hvc0 is specified in SERIAL_CONSOLES in qemuarm.conf
and qemuarm64.conf, but it is not in /proc/consoles and
SERIAL_CONSOLES_CHECK is not specified, leaving getty to attempt to
enable hvc0. Add SERIAL_CONSOLES_CHECK to both conf files so that
hvc0 isn't enabled if it hasn't been set there or in local.conf.

running ptests on qemuarm returns fails since it finds errors in kernel
logs like below
***********************
Central error: [ 4.338465] pci-host-generic 4010000000.pcie: ECAM ioremap failed
***********************
Since its a 32bit kernel 4010000000 address is truncated to 10000000 and ends up
in conflicts with VIRT_PCIE_MMIO, which ranges from 0x10000000 to 0x3efeffff
This is happening because the linux-yocto kernel is not compiled with
LPAE support, however, virt machine for qemuarm assumes that by default
Should LPAE be enabled by default in kernel config is a separate
question

There was a discussion about what amount of RAM is appropriate for a
default; the outcome was that for now it is still 256M. Some qemu machine
definitions have however set this to 512M so for the sake of
treating all architectures fairly, they are reset back to 256M.
Also runqemu is adjusted to use 256M if QB_MEM is not set at all.

Add new QEMU BSP for a Arm Cortex-A15 system and use this as qemuarm,
moving the old armv5te Versatile PB based machine to qemuarmv5.
The new machine uses the QEMU virt machine type, which should be
faster to emulate and updates the qemuarm support to a modern
architecture.

Just adding `-device virtio-rng-pci' to the QEMU invocation will
add the device with a default host backend. As of QEMU 1.3+,
the default backend is to use the host's /dev/random as a
source of entropy. [1]
When the entropy pool is empty, reads from /dev/random will
block until additional environmental noise is gathered. [2]
For Yocto, if call runqemu frequently, it will consume lots
of host's /dev/random, and kernel finish crng init in guest get
more and more slowly.
Here are 4 times runqemu boot test:
[ 3.464432] random: crng init done
[ 20.874030] random: crng init done
[ 23.583589] random: crng init done
[ 23.858945] random: crng init done
Modify entropy source to /dev/urandom device on the host which
returns random bytes using a pseudorandom number generator seeded
from the entropy pool. Reads from this device do not block and
kernel finish crng init in guest will not delay.
Of course, the side effect is obviously, we lost the quality of
randomness, but the modification is only on runqemu script
rather than real embedded device, and it benefits oeqa efficiency
in which many cases call runqemu especially multiple oeqa builds
on one host.
After apply the fix:
[ 3.364670] random: crng init done
[ 4.619061] random: crng init done
[ 3.403897] random: crng init done
[ 3.450717] random: crng init done

These functions were moved to meta/lib/oe in 2010 and the base_* functions in
utils.bbclass were intended to be a short-term compatibility layer. They're
still used in a few places, so update the callers to use the new functions.

linux-yocto: drop 4.8 recipes
We have 4.1 (LTSI), 4.4 (LTS), 4.9 (LTS/LTSI) and 4.10 available in

the version selection under control.

Use weak assignment for SERIAL_CONSOLES in qemu configuration files so that
the value could serve as a default value and could be easily overridden in
configuration files like local.conf.
When using the default value for SERIAL_CONSOLES in qemux86-64,we would have
annoying messages on console complaining about respawning getty on ttyS1.
Although the value is set by purpose, at least we need to provide an easy way
to override it.

Not all QEMU machines (outside of those available in OE-Core) are
capable of using the virtio-rng-pci device due to various machine models
not having a pci/virtio bus. This makes it such that the use of the
'-device virtio-rng-pci' flag to QEMU is machine specific.
This patch removes the general addition of the flag to all runqemu
targets and adds the flag into the QB_OPT_APPEND for all the qemu*
machines in OE-Core that support its use (which is all of them).

The base_version_less_or_equal() will raise errors if
PREFERRED_VERSION_linux-yocto is None. For example, when we build
DISTRO = "nodistro", PREFERRED_VERSION_linux-yocto is not be defined
since it is defined in poky.conf, and then bitbake will
choose the higher version which is 4.8 currently, so set
PREFERRED_VERSION_linux-yocto to 4.8, otherwise, runqemu can't boot it.

qemu can freeze and stop responding if the socket buffer connected to a tcp
serial connection fills up. This happens of course when the reader of
the serial data doesn't actually read it.
This happened in the qemurunner code, because after checking for the
"login:" sentinel, data was never again read from the serial connection.
This patch solves the potential freeze by adding a thread to continuously
read the data from the console and log it. So it also will give a full log
of the console, rather than just up to the login prompt.
To simplify this patch, another serial port was also added to use for the
sole purpose of watching for the sentinel as well as being the interactive
serial port. This will also prevent the possibility of lots of debug
data on the console preventing the sentinel value from being seen due to
interleaved text.

There is currently consideradble confusion over how the tune files operate
and how these interact with the rest of the build system. This update/overhaul
changes things so the tune files are primarily resonsible for setting:
TUNE_ARCH - What was formerly set as TARGET_ARCH and is the value that
represents the architecture we're targetting.
TUNE_PKGARCH - The value that represents the tune confuration that this set
of tune parameters results in.
This allows the significant improvement that the core can now always determine
the target architecture value, even when TARGET_ARCH needs to be reset to
something different and likewise, there is one package architecture variable
the core can reference allowing simplification of the BASE_PACKAGE_ARCH, PACKAGE_ARCH
and FEED_ARCH variables.

The different kernel recipes encapsulate functionality groups for machines,
therefore it makes sense to have all the QEMU machines using the same kernel
recipe.
Switch the QEMU machines to default to the "linux" recipes for their kernel
and bump the latest recipe from linux-2.6.32 to 2.6.33.
