fixes for issues observed when using spi_flash
This MR fixes three unrelated issues:
- Race condition in spi_flash_enable_interrupts_caches_and_other_cpu
when operations on unpinned tasks are performed.
The issue is reported in https://github.com/espressif/esp-idf/pull/258
- esp_intr_noniram_disable doesn’t disable interrupts when compiled in
release mode. This issue manifested itself with an illegal instruction
exception when task WDT ISR was called at the time when flash was
disabled.
Fixes https://github.com/espressif/esp-idf/issues/263.
- Tick hooks on CPU1 were not called if CPU0 scheduler was disabled for
significant amount of time (which could happen when doing flash erase).
The issue manifested itself as “INT WDT timeout on core 1” error.
Fixes https://github.com/espressif/esp-idf/issues/219.
