Before:
The cache won't be disabled when XIP on psram. But during flash
erasing/programming, read data will be courrupt.
When XIP in psram is enabled, the image is not mapped to the cache so
usually there will be no flash access. The only way to read from flash
is via the driver or use mmap. The driver has protection during erasing,
while th mmap region not.
Now:
Mmap APIs provide a flag to make mmap->unmap region mutually exclusive
to flash erase/programming when XIP from psram. SPI Flash write APIs
will benefit from this. When the flag is used, no concurrent access to
mapped region will happen while writing; otherwise the cache will be
disable to avoid data corruption.
Most ESP-IDF APIs calls mmap with this flag. As for users calling
mmap-like APIs directly, they can choose whether to enable this by a
flag.

Trim bootloader size by moving some logs to DEBUG. Allows
compiling bootloader on P4 with CONFIG_ESPTOOLPY_FLASHMODE_QIO
without changing partition table offset
MMU_LL_END_DROM_ENTRY_VADDR is an int-typed constant on several targets,
so logging it with PRIx32 (uint32_t) triggered -Werror=format=. Use the
plain %x specifier which matches the int type.
Closes https://github.com/espressif/esp-idf/issues/18857
For the SoCs that support configurable MMU page size, it is possible
that the bootloader and application are built with different MMU page
size configuration. This mismatch is not supported at the moment and
application verification fails (at bootup or during OTA update).
Configuring MMU page size helps to optimize the flash space by having
smaller alignment and padding (secure) requirements. Please note that
the MMU page size is tied with the flash size configuration at the
moment (`ESPTOOLPY_FLASHSIZE_XMB`).
This MR ensures that application verification happens using the MMU page
size configured in its binary header. Thus, bootloader and application
can now have different MMU page sizes and different combinations shall
be supported.
There are some register description errors in parts of rom/gpio.h
This commit update the incorrect comments in rom/gpio.h And now
esp_rom_gpio.h is recommend instead of rom/gpio.h. So this commit adds
macro SIG_GPIO_OUT_IDX in esp_rom_gpio_connect_out_signal
function and removes the reference to gpio.h in some source files.
Closes https://github.com/espressif/esp-idf/issues/11737
