Andy Piper 2cdc202d19 AP_HAL_ChibiOS: use non-cachable SRAM3 for DMA on H743 
Adjust SRAM1+SRAM2 to 256k as describe in the H743 reference manual
Provide access to mem_info() information

Andrew Tridgell 408f8b3940 HAL_ChibiOS: added check for overwrite of nullptr on H7 
the STM32H7 has 64k of ITCM memory at address zero. We allow
allocation of everything except the first 1024 bytes. This checks for
those reserved bytes being overwritte, which would indicate a write to
nullptr

Andrew Tridgell d1565a96c5 HAL_ChibiOS: wrap cacheBuffer functions 
needed to avoid problem with end() method in UARTDriver shadowing with
F7 implementation of cache macros

Andrew Tridgell 26d1371d25 HAL_ChibiOS: separate out DMA allocation for sdcard IO 
this fixes an issue with DMA to SPI6 on STM32H7. On the H7 SRAM4 can
be used for DMA and BDMA to all devices except for SDMMC which uses
IDMA.

by separating out DMA of sdcard data from other data we can arrange
for DMA to all devices to work

Andrew Tridgell cda1959629 HAL_ChibiOS: added support for more flexible memory regions 
this allows for an arbitrary number of memory regions, with each one
flagged as DMA safe, fast or normal

Michael du Breuil 8c464572d8 AP_HAL_ChibiOS: Use a less clever version of realloc 
The clever version loses access to memory, and is excessively hard coded

Andrew Tridgell c273b23940 HAL_ChibiOS: moved MCU config to python database 
this moves the key MCU config variables related to memory to the
python MCU database, allowing the hwdef.dat to be considerably simpler

Andrew Tridgell 2493cdbcb6 HAL_ChibiOS: switch to new bouncebuffer system 
this removes the dma_flush and dma_invalidate methods and uses a
common bouncebuffer system for all CPU types. This enables microSD
support on STM32F7
 2018-06-06 07:15:41 +10:00
Andrew Tridgell eec4a12cc2 HAL_ChibiOS: switched to using DTCM memory for DMA 
this uses SRAM1 and SRAM2 for main memory, which enables the use of the
data cache for faster operation, and using DTCM for all DMA operations.

Andrew Tridgell 2087354939 HAL_ChibiOS: align buffers to STM32F7 cache lines 
this allows for DMA flush and invalidate operations to work on all
dynamically allocated memory

bugobliterator 5feef04f5f HAL_ChibiOS: add support for CCM memory 
this uses DMA bounce buffers for bus transfers, and falls back to CCM
ram in allocations if the type is unspecified
