Andrew Tridgell 6c712c9001 HAL_ChibiOS: use SRAM1 as first ram segment on H7 
this is needed to give the linker more than 128k for static variables
with double precision maths.

Andrew Tridgell 6b9e4161cb HAL_ChibiOS: removed UDID_START from all MCU defs 
use UID_BASE from ChibiOS headers

Andrew Tridgell 61c829d624 HAL_ChibiOS: only use SRAM4 for DMA for now 
we can enable others when we have an allocation interface that
specifies the peripheral type

Iampete1 2377d33417 AP_HAL_ChibiOS: H7 set SRAM4 to no cache and allow DMA 2021-04-07 17:10:45 +10:00
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 61d036acf3 HAL_ChibiOS: added build time check for right system clock 
this helps prevent cases where we underclock a chip due to mistake in
headers or hwdef.dat

Andrew Tridgell 7a812a5516 HAL_ChibiOS: use cortex m7 instructions on F7/H7 2020-01-25 08:50:09 +11:00
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

Andrew Tridgell 50b7b7beb5 HAL_ChibiOS: disable DTCM on H7 for now 
DTCM doesn't allow for DMA yet
