The race condition is very unlikely on real hardware but can be observed with
qemu under heavy load.
Also add missing `memw` instructions which are generated by the C compiler but
absent in the assembly code.

Closes https://github.com/espressif/esp-idf/issues/11433
For RAM loadable ELF, entire firmware is running from RAM and hence the
IROM/DROM size must be treated as 0 (no cache mappings created for
code/rodata).
Memprot functions are no longer placed by default in IRAM,
selecting ESP_PANIC_HANDLER_IRAM will still force panic related memprot
functions to be placed in IRAM.
esp_rom_spiflash_attach is called in cpu_start.c when it's
CONFIG_APP_BUILD_TYPE_RAM && !CONFIG_APP_BUILD_TYPE_PURE_RAM_APP.
This function will:
- reset MSPI
- configure MSPI IOs
- configure MSPI into slow read mode
Prior to this commit, this function is put quite late. It's OK for chips
earlier than C6. On C6 and H2, MMU registers are in SPI_MEM_x, so
resetting MSPI registers will also reset MMU registers.
After this commit, this funciton is called eariler, before
cpu_start.c: bootloader_init().
esp_execute_shared_stack_function always restored the stack watchpoint
regardless of CONFIG_FREERTOS_WATCHPOINT_END_OF_STACK. This would lead
to an abondoned but active watchpoint on a former stack once the task
calling esp_execute_shared_stack_function is deleted, if
CONFIG_FREERTOS_WATCHPOINT_END_OF_STACK is inactive.
This has been fixed now.

If the TimerGroup 0 clock is disabled and then reenabled, the watchdog
registers (Flashboot protection included) will be re-enabled, and some
seconds later, will trigger an unintended reset.

usb_serial_jtag: Improve the code for the issue of usb cdc device unable to work during sleep
Closes IDFGH-6887
See merge request espressif/esp-idf!20973
1. Remove RTC_CLOCK_BBPLL_POWER_ON_WITH_USB Kconfig option
During sleep, BBPLL clock always gets disabled
esp_restart does not disable BBPLL clock, so that first stage bootloader log can be printed
2. Add a new Kconfig option PM_NO_AUTO_LS_ON_USJ_CONNECTED
When this option is selected, IDF will constantly monitor USB CDC port connection status.
As long as it gets connected to a HOST, automatic light-sleep will not happen.
Closes https://github.com/espressif/esp-idf/issues/8507
- Support SOC ROOT clock source switch
- Support CPU frequency change
- Support RTC SLOW clock source switch
- Support RTC SLOW clock + RC FAST calibration
Remove FPGA build for esp32h2
