Krzysztof Chruściński	4e880e62dc	drivers: cache: nrf: Use CONFIG_DCACHE_LINE_SIZE Use Kconfig instead of fixed value in the driver code. Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>	1 year ago
Krzysztof Chruściński	9f6567b87a	drivers: cache: nrf: Optimize operation Apply changes which significantly speed up cache operations. Removed k_busy_wait from function which polls for cache busyness. Removed spinlock from cache operation. Lock taking and releasing takes time and it is faster to check if LINEADDR changed after performing the operation. If LINEADDR changed then it indicates that current context was preempted by another cache operation. If such state is detected current operation is repeated.

Krzysztof Chruściński	b83a11281d	drivers: cache: nrf: Fix case when driver may hang Driver was disabling cache before full range operations and that was causing hanging on polling for cache busy status since state was never changing (because cache was disabled). Additionally, added flushing to data cache disabling. If flushing is not performed then execution fails since data in cache is lost.

Krzysztof Chruściński	73d4f58b98	drivers: cache: nrf: Handle issue with LINEADDR on secure builds nrf54h20 has a bug that requires to manually set 28th bit in the line address. 28th bit indicates secure memory space. Add handling to the cache driver. Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>	1 year ago
Witold Lukasik	6d3009ff2b	drivers: cache: add Nordic cache driver Add Nordic driver for cache. Signed-off-by: Witold Lukasik <witold.lukasik@nordicsemi.no>	1 year ago
