The board_hw_defs.c file should only contain static
const declarations that only describe the hardware.
All other non-const variables should be put into one
of the pios_board.c files.
The PIOS_MASTER_CLOCK has been removed in favor of
PIOS_SYSCLK (the master clock value,168000000 for revolution)
PIOS_PERIPHERAL_APB1_CLOCK and
PIOS_PERIPHERAL_APB2_CLOCK
Look at STM32F4xx_Revolution.h for the list of timer/peripheral and APB them belongs.
for sensing and then load different config for CC and CC3D. Updated the
bootloader as well. Also changed the PIOS_USB_CheckAvailability function to
only return the sense signal and not the transfer_possible flag as this is not
set in time for the bootloader on CC3D for some reason.
Board specific HW configuration is now collected in a single .c
file for each board. This HW configuration is #include'd into
the FW, BL and BU builds for each board.
These new .c files are found in:
flight/board_hw_defs/<board_name>/board_hw_defs.c
Parts of this information were previously duplicated between
the BL and FW builds. This commit cleans up the duplication.
Using a #include on a .c file is a bit ugly but it allows us
to ensure that all of the symbols in the board_hw_defs.c file
are *ONLY* used in the PIOS_Board_Init() function for each
software build.
