Michael (XIAO Xufeng) 44bd6f72bc spi: fix the crash when callbacks are not in the IRAM ... Introduced in 9c23b8e5 and 4f87a62f. To get higher speed, menuconfig options are added to put ISR and other functions into the IRAM. The interrupt flag ESP_INTR_FLAG_IRAM is also mistakenly set when the ISR is put into the IRAM. However callbacks, which are wrote by the user, are called in the master and slave ISR. The user may not be aware of that these callbacks are not disabled during flash operations. Any cache miss during flash operation will cause panic. Essentially IRAM functions and intrrupt flag ESP_INTR_FLAG_IRAM are different, the latter means not disabling the ISR during flash operations. New bus_config flag intr_flags is offered to help set the interrupt attribute, including priority level, SHARED, IRAM (not disabled during flash operations). It introduced a small BREAK to IDFv3.1 (but the same as IDFv3.0) that the user has to manually set IRAM flag now (therefore he's aware of the IRAM thing) to void the ISR being disabled during flash operations.		2018-12-04 21:35:20 +08:00
