This commit gives basic mmu driver framework. Now it is able to maintain
mmu virtual address usage on esp32, esp32s2 and esp32s3. Usage to
external virtual address should rely on mmu functions to know which
address range is available, instead of hardcoded.
This commit also improves psram memory that is added to the heap
allocator. Now it's added to the heap, according to the memory
alignment.

uart: update console docs about frequency for ESP32-C2, move frequency of clock sources out of HAL
Closes IDF-5424 and IDF-4332
See merge request espressif/esp-idf!19274
esp_light_sleep_start() will stall the other CPU via esp_ipc_isr_stall_other_cpu(). After stalling the other CPU,
will call esp_clk_... API which themselves take locks. If the other stalled CPU is holding those locks, this will
result in a deadlock.
This commit adds a workaround calling esp_clk_private_lock() to take the lock before stalling the other CPU.
esp_clk used to be protected using _lock_t (i.e., a FreeRTOS Mutex). However, esp_clk API is current called from
from critical sections, thus mutex should not be used (as they can be blocking).
This commit updates esp_clk to use spinlocks for critical sections instead.
bugfix: esp32s3 DCache data memory is retention dma inaccessible
Closes IDFCI-1409, IDFCI-1410, IDFCI-1411, IDFCI-1412, and IDFCI-1413
See merge request espressif/esp-idf!19365
Since cpu retention dma use rc fast as clk source, so rc_fast_digi
will be enabled when we config to pd cpu. And cpu retention does not
need rc fast keep on during light sleep. So, if we use rc_fast_digi
to determine whether rc fast can be powered down, then cpu and and
rc fast cannot pd at the same time.
- Remove esp_cpu_in_ocd_mode() from esp_cpu.h. Users should call esp_cpu_dbgr_is_attached() instead.
- Remove esp_cpu_get_ccount() from esp_cpu.h. Users should call esp_cpu_get_cycle_count() instead.
- Remove esp_cpu_set_ccount() from esp_cpu.h. Users should call esp_cpu_set_cycle_count() instead.
- Other IDF components updated to call esp_cpu_dbgr_is_attached(), esp_cpu_get_cycle_count() and esp_cpu_set_cycle_count() as well.
This commit marks all functions in soc_hal.h and soc_ll.h as deprecated.
Users should use functions from esp_cpu.h instead.
Also added missing wrap funcions for esp_cpu_stall() in test_panic.c files.
This commit marks all functions in interrupt_controller_hal.h, cpu_ll.h and cpu_hal.h as deprecated.
Users should use functions from esp_cpu.h instead.
This function removes the following legacy atomic CAS functions:
From compare_set.h (file removed):
- compare_and_set_native()
- compare_and_set_extram()
From portmacro.h
- uxPortCompareSet()
- uxPortCompareSetExtram()
Users should call esp_cpu_compare_and_set() instead as this function hides the details
of atomic CAS on internal and external RAM addresses.
Due to the removal of compare_set.h, some missing header includes are also fixed in this commit.
esp_cpu_compare_and_set() abstracts the atomic compare-and-set instruction by
hiding the details of whether the target variable is in internal or external
RAM. This commit updates "spinlocks.h" as follows:
- esp_cpu_compare_and_set() is now called instead of "compare_set.h"
- Refactored spinlock logic to be more optimized and have more stringent sanity checks
This commit fixes esp_cpu_compare_and_set() in the following ways
- Removed call to esp_ptr_external_ram() as it incurred > 80 CPU cycles (due to multiple nested
function calls, and those functions not being in IRAM). We now check manually if the pointer
is in external RAM for increased speed.
- Fixed infinite wait when attempting to get the external_ram_cas_lock. The function should
return immediatley if any part of the compare and set call fails.
- The preprocessor conditions of esp_cpu_compare_and_set() to depend on CONFIG_SPIRAM instead
of SOC_SPIRAM_SUPPORTED. Even if the target supports SPIRAM, we only need the external RAM
compare and set feature if SPIRAM is enabled.
Also fixed incorrect inclusion of esp_intr_alloc.h in esp_cpu.h
