`__main_thread_stack_base__` and `__main_thread_stack_end__` are
variables whose address is defined to be the corresponding part of the
stack. These are declared as `extern stkalign_t` in ChibiOS code, and
being declared as `extern uint32_t` in ArduPilot code creates a warning
at link time when using LTO. Correct the declaration to eliminate this
warning.
Also update `__main_stack_base__` and `__main_stack_end__` which don't
currently trigger this warning but serve similar purposes and so might
in the future.
The hardware expects an alignment of `stkalign_t` (which is 8 bytes) and
the linker script defines the variable values with this alignment as
well, so this is safe.
No code size or functional change.
this isn't built on the firmware server, so we won't notice when it dies
In this case the SMBUS batter define was being set differently
Also remove some redundant defines which come from includes anyway
this fixes DMA failures affecting IMUs on H743. The reason for the
failure is not yet clear, but this reverts back to our old stragegy of
always using the bouncebuffer on H7 as a quick workaround
SERIAL_ORDER has been around for a few years now and UART_ORDER is
rejected by the hwdef script, so support for UART_ORDER and associated
processing in the hwdef script is removed, along with the order
conversion script.
add support to tell if shared DMA channel is actually shared
avoid starting and stopping the timer peripheral with bdshot
ensure that rcout DMA allocation and deallocation happens entirely within the lock

ensure that a cascading event will always come when expected on rcout
allow timeouts when using cascading dshot
always rotate telemetry channel after trying to capture input
