This commit removes the dependency on portUSING_MPU_WRAPPERS on the Xtensa port
of IDF FreeRTOS. This dependency was added due to a hack implemented in the
upstream port that required the usage of the "xMPUSettings" member of the TCB.
The "xMPUSettings" would be used as a pointer to the task's coprocessor save
area on the stack, even though FreeRTOS MPU support was not available.
The hack has now been removed, and the CPSA pointer is now calculated using
a combination of constant offsets values and the pxEndOfStack member of the
TCB.
Note: This impelemtation was copied from the Xtensa port of Amazon SMP FreeRTOS.
All the partition handling API functions and data-types were moved from the 'spi_flash' component to the new one named 'esp_partition'. See Storage 5.x migration guide for more details
This commit updates the esp_cpu.h API. The new API presents a new
abstraction of the CPU where CPU presents the following interfaces:
- CPU Control (to stall/unstall/reset the CPU)
- CPU Registers (to read registers commonly used in SW such as SP, PC)
- CPU Interrupts (to inquire/allocate/control the CPUs 32 interrupts)
- Memory Port (to configure the CPU's memory bus for memory protection)
- Debugging (to configure/control the CPU's debugging port)
Note: Also added FORCE_INLINE_ATTR to the DoxyFile in order to pass doc
builds for esp_cpu.h
This commit updates the watchdog documentation as follows:
- Removes IWDT API reference as it is now considered private API
- Rewrite IWDT section
- Fix headers, types, and formatting
1. Clean up clk usage in IDF, replace rtc_clk_xtal/apb_freq_get with
upper level API esp_clk_xtal/apb_freq
2. Fix small errors and wrong comments related to clock
3. Add clk_tree_defs.h to provide an unified clock id for each chip
Modify the NGed drivers to adopt new clock ids
This commit refactors the ulp component.
Files are now divided based on type of ulp, viz., fsm or risc-v.
Files common to both are maintained in the ulp_common folder.
This commit also adds menuconfig options for ULP within the ulp
component instead of presenting target specific configuations for ulp.
