when storage is between the bootloader and main program flash then the
flash size available to the bootloader needs to stop at the sector for
the storage flash.
Similarly, if storage is at the end of flash, then total flash size
needs to be limit
this ensures we don't try to build a firmware that encroaches on
program space
This reverts commit 5de6c690d8.
That commit broke the build for the affected board as the chibios
headers rely on the name of the file matching a ifdef
this fixes an issue found by Andy Piper where the H743 bootloader gets
a hard fault in the DCache enable code when SRAM1 is primary memory.
This is the simplest fix I could think of, and avoids the problem by
making DTCM the first segment in the bootloader.
Note that we can't use DTCM as first segment for main firmware since
we went to double precision EKF as the static variables don't fit
this changes the heuristics for UART TX DMA allocation to greatly
reduce the chances of DMA contention causing long delays on other
devices
This fixes issues with FETTec driver output and gimbal status messages
as reported by Amilcar and OlliW. The problem is particularly bad when
no GPS is connected to GPS1 on fmuv3 and derived boards (such as
CubeBlack)
key changes:
- remember the contention_counter across begin() calls, as the GPS
calls begin with new baudrates regularly
- added a is_shared() API to Shared_DMA, allowing the UART driver to
avoid TX DMA on shared streams when at low baudrates.
