* get rid of BSP layer * sector_cache: init in any case * new sd-spi driver: init * Delete stm32_adafruit_sd.c.old * Delete spi_sd_hal.c.old * Storage: faster api lock primitive * Threads: priority control * Flags: correct error code * Spi: dma mode * SD-card: use DMA for big blocks of SPI data * Fix wrong SD_TOKEN_START_DATA_MULTIPLE_BLOCK_WRITE value * do not memset cache if it is NULL * remove top-level timeouts * sd hal: disable debug * Furi HAL: DMA * Furi HAL RFID: use furi_hal_dma * Furi HAL DMA: tests * Furi HAL DMA: docs * rollback "Furi HAL RFID: use furi_hal_dma" * 4 channels taken from DMA manager for core HAL. * Furi HAL DMA: live fast, die young * RPC tests: increase message buffer * SPI HAL: use second DMA instance * sd hal: new CID getter * SPI hal: use non-DMA version if kernel is not running * IR hal: generalize DMA definition * storage: add CID data to sd info * RFID hal: generalize DMA definition * SUBGHZ hal: generalize DMA definition. Core hal moved to DMA2. * Storage: small optimizations, removal of extra mutex * Storage: redundant macro * SD hal: more timeouts * SPI hal: DMA init * Target: make furi_hal_spi_dma_init symbol private * Update F18 api symbols Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
