It was found that the test latency_measure, when compiled
for microkernel, would fail on the ARC. This because the
trap handler, used by irq_offload, wasn't supporting thread switching.
This submission adds the code to do that, and the code size is
bigger only when CONFIG_MICROKERNEL is defined.
To keep code a bit smaller, there is a trick exploited here where
the AE bit is cleared in the STATUS32 register and in AUX_IRQ_ACT,
bit 1 is set, to make it appear as if the machine has interrupted
at priority 1 level. It then can jump into some common interrupt
exit code for regular interrupts and perform an RTIE instruction
to switch into the new thread.
test/latency_measure/microkernel now passes.

Moved setting of specific Cortex-M compiler flags in each SoC directory
unify setting them in the arch/arm/soc Makefile.
Add flags for Cortex M0, M0+, M1, M3, M4, and M7. However only
CONFIG_CPU_CORTEX_M3 and CONFIG_CPU_CORTEX_M4 are supported at this time
As part of this change converted Kbuild files for some SoCs into
Makefiles as the Makefiles would be empty otherwise.

The TX fifo threshold is pretty arbitrary.
Set this too big and too many interrupts will occur
for no good reason. Set it too small, and latency
in the SPI transactions is introduced. User's will probably
have to tune this per their application and SPI frequency, etc.
I think setting this to 50% is a good guess for now.

The ethernet driver generates a lot of spurious interrupts.
These spurious interrupts have two sources:
1) The Mac Management Counter (MMC) module generates a lot of interrupts
(GMI - bit 27 of the status register). Unfortunately the Interrupt
enable register doesn't allow us to enable/disable it (bit 27 is
reserved). Therefore the only way to mask this interrupt is to mask
all the MMC interrupts (register REG_MMC_RX_INTR_MASK,
REG_MMC_TX_INTR_MASK and REG_MMC_RX_IPC_INTR_MASK). By default
these interrupts are not masked.
2) The RX interrupt is not correctly acknowledged. According to the
datasheet, NIS is a sticky bit and must be cleared (by writing 1
to this bit) each time a corresponding bit, which causes NIS to
be set, is cleared.

The ethernet driver calls net_set_mac before net_init is
called (ie before the uip stack has been fully initialized).
Unfortunately net_set_mac calls the function uip_ds6_set_lladdr.
Therefore this function is called before uip_ds6_init: this is an
issue as uip_ds6_set_lladdr is setting some static data which are
going to be erased by uip_ds6_init. In some case it could even lead
to a system hang due to a timer set twice.
To fix this issue net_set_mac should check whether net_init has been
already called. If not net_set_mac should simply copies the mac
address into uip_lladdr. Indeed uip_ds6_init automatically calls
uip_ds6_set_lladdr for the address stored into uip_lladdr.

The line below is wrong and useless:
lladdr->state = ADDR_AUTOCONF;
Indeed the three possible values for the state attribute are:
ADDR_TENTATIVE, ADDR_PREFERRED or ADDR_DEPRECATED. ADDR_AUTOCONF
is one possible value for the type attribute.
Moreover uip_ds6_set_lladdr already set the type attribute to
ADDR_AUTOCONF (this done through the call to the function
uip_ds6_addr_add).
Therefore this issue has been simply fixed by removing the line.

The .nd on a branch is WRONG if its an unconditional branch. Not needed.
On conditional branches its a compiler feature that is not yet functional
with ARC targets. Typical code for this compiler can use .d to put
something in the delay slot of an instruction, but using .nd is probably
never wanted.
