bootcfg: use UAVobj to control boot-time HW config This should mark an end to the compile-time selection of HW configurations. Minor changes in board initialization for all platforms: - Most config structs are marked static to prevent badly written drivers from directly referring to config data. - Adapt to changes in .irq fields in config data. - Adapt to changes in USART IRQ handling. Major changes in board initialization for CC: - Use HwSettings UAVObj to decide which drivers to attach to the "main" port and the flexi port, and select the appropriate device configuration data. - HwSettings allows choosing between Disabled, Telemetry, SBUS, Spektrum,GPS, and I2C for each of the two ports. - Use ManualControlSettings.InputMode to init/configure the appropriate receiver module, and register its available rx channels with the PIOS_RCVR layer. Can choose between PWM, Spektrum and PPM at board init time. PPM driver is broken, and SBUS will work once it is added to this UAVObj as an option. - CC build now includes code for SBUS, Spektrum and PWM receivers in every firmware image. PIOS_USART driver: - Now handles its own low-level IRQs internally - If NULL upper-level IRQ handler is bound in at board init time then rx/tx is satisfied by internal PIOS_USART buffered IO routines which are (typically) attached to the COM layer. - If an alternate upper-level IRQ handler is bound in at board init then that handler is called and expected to clear down the USART IRQ sources. This is used by Spektrum and SBUS drivers. PIOS_SBUS and PIOS_SPEKTRUM drivers: - Improved data/API hiding - No longer assume they know where their config data is stored which allows for boot-time alternate configurations for the driver. - Now registers an upper-level IRQ handlerwith the USART layer to decouple the driver from which USART it is actually attached to.
