Richard Barry 7cc42b2ab6 Save changes to the RISC-V port layer before making changes necessary to support pulpino too:
+ Switch positions of the asm functions used to start the kernel and handle traps to enable one to reference to the other.
+ Handle external interrupts (working with Renode emulator).
+ The _sp linker variable is now called __freertos_irq_stack_top.

Each real time kernel port consists of three files that contain the core kernel
components and are common to every port, and one or more files that are 
specific to a particular microcontroller and or compiler.

+ The FreeRTOS/Source directory contains the three files that are common to 
every port - list.c, queue.c and tasks.c.  The kernel is contained within these 
three files.  croutine.c implements the optional co-routine functionality - which
is normally only used on very memory limited systems.

+ The FreeRTOS/Source/Portable directory contains the files that are specific to 
a particular microcontroller and or compiler.

+ The FreeRTOS/Source/include directory contains the real time kernel header 
files.

See the readme file in the FreeRTOS/Source/Portable directory for more 
information.
