Benjamin Valentin	3dd5f5c789	sys/bit: add bit_checkXX() functions	2021-06-02 14:07:17 +02:00
Marian Buschsieweke	51db33375a	sys/bit: provide CPU_HAS_SRAM_BITBAND ... CPU_HAS_SRAM_BITBAND can be used to check whether bit-banding is supported for all of SRAM. With partially supported bit-banding, this feature is more of a foot gun that a valuable tool.	2021-01-20 09:18:09 +01:00
Benjamin Valentin	e300dfe47e	sys/bit: move bit.h from cortexm_common/ to sys/ ... The bit access functions are not tied to Cortex-M CPUs, here they only provide optimisations via bit-banding. But the functions are generally useful - so move them to an arch independent location.	2020-12-08 17:07:41 +01:00
