Upstream xtensa exception handling will save PS, PC, and a0 registers
together when saving a minimal context. This commit ppdates the xtensa
exception handling to match upstream behavior.
The following files were deleted:
- components/esp_hw_support/include/soc/cpu.h
- components/soc/esp32s3/include/soc/cpu.h
The following functions are deprecated:
- get_sp()
The following functions declared in soc/cpu.h are now moved to esp_cpu.h:
- esp_cpu_configure_region_protection()
The following functions declared in soc/cpu.h are now moved to components/xtensa/include/esp_cpu_utils.h:
- esp_cpu_process_stack_pc()
All files with soc/cpu.h inclusion are updated to include esp_cpu.h instead.

peripheral enable/disable usually should be managed by driver itself,
so make it as espressif private APIs, not recommended for user to use it
in application code.
However, if user want to re-write the driver or ports to other platform,
this is still possible by including the header in this way:
"esp_private/peripheral_ctrl.h"
esp_restart()/panic_restart() never resets the Digital system (so far required only by the Memprot feature) as there's a typo in the corresponding #define:
it checks CONFIG_ESP_SYSTEM_CONFIG_MEMPROT_FEATURE instead of CONFIG_ESP_SYSTEM_MEMPROT_FEATURE.
Issue fixed.
IDF-4094
There was race condition where interrupt entries set by APP cpu core
could have been cleared during PRO cpu startup.
This was observed while setting up "cache access error" interrupt in
SMP mode for ESP32-S3.
This fix allows to NOT modify or clear any entries set by other core
(APP or PRO) and thus avoiding any race conditions during startup code.
As branches/jumps on Xtensa have a maximum range for the destination, it is
unsafe to refer to a label to another compilation unit in a branch/jump instruction.
The labels have been replaced by absolute addresses.
components/os: Move ETS_T1_WDT_INUM, ETS_CACHEERR_INUM and ETS_DPORT_INUM to l5 interrupt
components/os: high level interrupt(5)
components/os: hli_api: meta queue: fix out of bounds access, check for overflow
components/os: hli: don't spill registers, instead save them to a separate region
Level 4 interrupt has a chance of preempting a window overflow or underflow exception.
Therefore it is not possible to use standard context save functions,
as the SP on entry to Level 4 interrupt may be invalid (e.g. in WindowUnderflow4).
Instead, mask window overflows and save the entire general purpose register file,
plus some of the special registers.
Then clear WindowStart, allowing the C handler to execute without spilling the old windows.
On exit from the interrupt handler, do everything in reverse.
components/bt: using high level interrupt in lc
components/os: Add DRAM_ATTR to avoid feature `Allow .bss segment placed in external memory`
components/bt: optimize code structure
components/os: Modify the BT assert process to adapt to coredump and HLI
components/os: Disable exception mode after saving special registers
To store some registers first, avoid stuck due to live lock after disabling exception mode
components/os: using dport instead of AHB in BT to fix live lock
components/bt: Fix hli queue send error
components/bt: Fix CI fail
