Dmitriy Korovkin f661feee55 IRQ_CONNECT_STATIC implementation for ARM platform
IRQ_CONNECT_STATIC() macro provides static interrupt registration.
It creates an entry for _sw_isr_table, table of interrupt handlers.

IRQ_CONFIG() macro provides interrupt controller configuration.
On ARM platform it configures the priority of each interrupt.

_sw_isr_table is implemented the way that each of it's elements
is located in individual section. Sections are marked a "linkonce",
thus when a device driver declares an interrupt handler, it overwrites
the default _sw_isr_table entry.

Peter Mitsis 8601dc9488 Break forced selection of CPU_CORTEX_M3
Makes the ARM CPU type a choice between CPU_CORTEX_M3 and CPU_CORTEX_M4
(similar to the choice of processor for x86). This completes the breaking
of the forced selection of CPU_CORTEX_M3 when CPU_CORTEX_M4 chosen, thereby
making CPU_CORTEX_M3_M4 the true umbrella option for the Cortex M3/M4
processors.

CPU_CORTEX_M3_M4 replaces CPU_CORTEXM3 as the umbrella option for Cortex M3/M4
processors.

NOTE: Selecting CPU_CORTEXM4 still currently forces the selection of
CPU_CORTEXM3.  Breaking that forced select will be done in a later commit.

Szymon Janc 6d27b0a33c Add simple UART driver
This driver is a very simple UART driver that can be used to implement
a protocol in application. It has no protocol logic and just allow
application to receive and send data over UART in platform independent
manner.

API is designed to minimize number of required memory copies.
Application is able to provide new buffer every time it decides to
consume received data. It is also able to just alter offset and
reuse current buffer eg if data was corrupted or otherwise invalid.

Instead of initializing the stack (when INIT_STACKS is enabled) in start_task()
and _fiber_start(), do it in _NewContext().  This helps to both reduce code
duplication AND ensure that all contexts get an initialized stack (previously
the background/idle task's was missed).

According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build.  This patch converts to them to the newer ccflags-y which also
fixes the problem.

Peter Mitsis 40b5200c73 Optimizations to _NewContext() and _NewContextInternal()
Since the address of the new context is known before _NewContext() is invoked
(due to it being passed a properly aligned stack), there is no longer any
need for _NewContext to return the pointer to the context.

Furthermore, as a direct result of the properly aligned stack, the pointer to
the new context does not need to be passed as a separate parameter since it
will always match the passed stack pointer.
