[PR] mcu/stm32h7: Disable caches not enabled by configuration [mynewt-core]

["kasjer (via GitHub)" <gi...@apache.org>]

kasjer opened a new pull request, #3780:
URL: https://github.com/apache/mynewt-core/pull/3780

   hal_system_init() only enabled instruction and data cache when STM32_ENABLE_ICACHE or STM32_ENABLE_DCACHE was set. Boot loader built with caches enabled leaves them on when it starts application, so application configured with caches disabled still ran with them enabled. This breaks code that relies on caches being off, e.g. stm32_eth driver that does no cache maintenance for DMA descriptors and buffers placed in cacheable RAM.
   
   Disable cache that is not requested by configuration if it is enabled at this point.
