20fa15c24a spi: fix block transfers
SPI block transfers were broken in commit r759.  Block
transfers are primarily used by the SD card interface so
this also broke accesses to the SD card.

SD card accesses should be fixed now.  Verified by writing
config objects in the GCS and confirming that they survived
a reboot of the OP board.

771a56ca9d com/usart: generalize com driver API
- Created a pluggable COM layer
- Converted COM + USART init into static initializers
  rather than typedefs
- Generalized the USB HID COM API to match the USART
  API.
- Changed USART and COM layers to be data driven rather
  than #ifdef'ing/switching on the specifics of each port

8d015a57d0 pios spi: support both master and slave configs
Added support for SPI slave configurations to the pios SPI layer.

Converted the board specific configuration for the PIOS SPI layer to
use const static initializers rather than #defines (see pios_board.c).

SPI interface between the OP board and the AHRS is now operational at
a basic level, capable of moving simple single byte messages between
boards.  Multi-byte, CRC protected messages will be added on top of this.

02e0017cbb stm32 lib: declare read-only parameters as const
Many of the STM32 library functions take a pointer to an
initialization structure.  In nearly every case, this struct
is a read-only (ie. const) parameter.

It is advantageous (and good coding practice) to actually declare
read-only data as const so that the compiler can place the const data
in the .rodata section which resides in flash and doesn't consume any
RAM.  This has the added bonus advantage that it is impossible for the
running application to corrupt the read-only data.

In order to allow passing pointers to const data into the library
functions, it is essential that the function prototypes also declare
their associated read-only parameters as const.  This commit adds
the const attribute to those parameters that are actually read-only.

8b5e1e8aea init cleanup: use irq stack during early init
No functionality changed.  Clean up only.

Make early init code (Reset_Handler) use the existing irq stack
rather than the hard-coded one.

Remove (now) unused references to the hard-coded stack.

Removed the link-time check for a minimal task stack in RAM since
FreeRTOS allocates user stacks from the heap which is already reserved
in the .bss section (as symbol xHeap).

918250868b irq_stack: correct one word overlap of _irq_stack_top
The previous fix in r652 was _almost_ right.  There was
still a one word (4-byte) overlap between _irq_stack_top
and the start of the data segment.

_irq_stack_end + _irq_stack_size leaves the '.' pointer at
the word immediatly after the stack.  This commit corrects
this error and places _irq_stack_top on the last word
_inside_ the reserved space for the irq stack.

6b2760da1a USB HID: basic COM functionality over USB HID
This fixes the COM interface over USB HID to the point where
it can establish and maintain solid communications with the UAVObject
Browser in the GCS.

Tested only on Linux.  The USB HID interface is still disabled for now
until it is tested successfully by a wider group.

Edit telemetry.c and set ALLOW_HID_TELEMETRY to 1 to enable telemetry
over the USB HID interface and report your results in the forum.

e892dcb033 bmp085: create semaphore prior to configuring irq
Since the EXTI and NVIC init routines automatically enable the IRQ when it
is configured, it is possible for the EOC interrupt to fire immediately
upon configuring the IRQ.

Since the handler for the EOC interrupt (EXTI15_10_IRQHandler) does a
xSemaphoreGiveFromISR, it is important to have the semaphore initialized
prior to enabling the interrupt.

Also, added missing include for altitude module.

41da33c920 irq_stack: provide a proper IRQ stack for FreeRTOS
The MSP (IRQ stack) was trampling across the data segment.  This was
especially disastrous in the USB interrupts since they allocate and
fill buffers on the stack.

The root of this trampling was that no RAM was being reserved for the
MSP and a hard-coded value of (0x20000400) was used as the initial MSP
base address.  This resulted in the first 1K bytes of the .data segment
overlapping with the IRQ stack.  As can be expected, all sorts of badness
resulted when interrupts were firing and trampling over variables.

This change reserves the first _isr_stack_size bytes at the beginning of
RAM for the MSP.  If an ISR call chain runs off of the end of the MSP,
a Hard Fault will be generated as the (now invalid) sp is accessed.

There are two stack pointers in the Cortex-M3 CPU.  These are MSP (Main
Stack Pointer) and PSP (Process Stack Pointer).

Which stack is in use at any given time is determined by the following table:

   Mode      CONTROL[ASPSEL]    Stack
   ----      ---------------    -----
   Thread    0                  MSP
   Thread    1                  PSP
   Handler   x                  MSP

Out of reset, the CPU is in Thread mode using the MSP.  The initial value
of the MSP is automatically loaded from address 0 (lowest word in boot
region -- typically FLASH) immediately prior to jumping to the reset vector.

When running at interrupt level, the Cortex-M3 always uses the MSP and the
ASPSEL bit is forced to zero.

FreeRTOS allocates a separate stack for each task upon task creation.  These
task stacks are allocated from the heap.  FreeRTOS sets the active stack to
the PSP whenever running in a task context (both in privileged mode and user
mode).

514d46f5b6 freertos: fix RTOS API calls from interrupt level
FreeRTOS has a strict requirement that even interrupt-safe API calls (ie.
those ending in "FromISR") can only be called from ISRs that are at lesser
or equal priorities to configMAX_SYSCALL_INTERRUPT_PRIORITY.  See the
"configKERNEL_INTERRUPT_PRIORITY and configMAX_SYSCALL_INTERRUPT_PRIORITY"
section at:
  http://www.freertos.org/a00110.html

The interrupt numbers used on the Cortex-M3 CPU has a somewhat backward
representation of the interrupt numbers so 255 = lowest priority and
0 = highest priority.

The calculation is further complicated by the STM32 implementation only using
the upper 4 bits of the priority value.  Only 0x00, 0x10, 0x20, ..., 0xE0, 0xF0
represent useful interrupt priorities.

FreeRTOS requires that MAX_SYSCALL and KERNEL interrupt priorities are expressed
as raw unshifted 8-bit values to be programmed directly into the BASEPRI register.

The priority values passed to the NVIC initialization, however, are expected
to be 4-bit values and are shifted up by 4 within NVIC_Init() for you.

The end result is that we need this arrangement:

[highest priority]
   NVIC_0 (Non-maskable-interrupt)
   NVIC_1
   NVIC_2
[Must NOT call FreeRTOS APIs above here]
   configMAX_SYSCALL_INTERRUPT_PRIORITY (now at 48 = 0x30 = NVIC_3)
   PIOS_IRQ_PRIO_HIGHEST (cur. NVIC_4)
   PIOS_IRQ_PRIO_HIGH    (cur. NVIC_5)
   PIOS_IRQ_PRIO_MID     (cur. NVIC_8)
   PIOS_IRQ_PRIO_LOW     (cur. NVIC_12)
   configKERNEL_INTERRUPT_PRIORITY (240 = 0xF0 = NVIC_15)
[lowest priority]

The previous config had configMAX_SYSCALL_INTERRUPT_PRIORITY set at
191 (0xBF) which is effectively NVIC_11.  This was allowing all of
the MID, HIGH and HIGHEST interrupt handlers to preempt the OS in
its critical sections.  Since some of these ISRs were calling
FreeRTOS APIs, this would result in corrupting internal data structures
within the OS.

It should be ok to move the configKERNEL_INTERRUPT_PRIORITY to a higher
priority as long as it is less than configMAX_SYSCALL_INTERRUPT_PRIORITY.
