Simple flash read command is not supported if Secure DL mode is enabled on the target.
Remove reference of this from the relevant docs part.

Closes IDF-6468
Unlike COMPILE_OPTIONS, COMPILE_DEFINITIONS CMake property assumes
values without the -D prefix, such as NAME or NAME=VAL.
Previously, IDF build system was passing COMPILE_DEFINITIONS build
property to CMake COMPILE_OPTIONS property, so -D prefix was not
a problem.
Now that COMPILE_DEFINITIONS CMake property is used, -D prefix has
to be removed.
(Note that this doesn't affect 'target_compile_definitions' function,
which strips -D prefix before adding the definition to the property.)
User's custom data are not taken into account during the CRC calculation anymore.
Which means taht the retained mem structure is not systematically erased
on each reboot anymore.
The following two functions in bootloader_support are private now:
* esp_secure_boot_verify_sbv2_signature_block()
* esp_secure_boot_verify_rsa_signature_block()
They have been moved into private header files
inside bootloader_private/
* Removed bootloader_reset_reason.h and
bootloader_common_get_reset_reason() completely.
Alternative in ROM component is available.
* made esp_efuse.h independent of target-specific rom header
Adding prop and lit sections to the ELF will let the debugger and the disassembler
have more info about data bytes present in the middle of the Xtensa
instructions, usually used for padding.
The change fixes thread-local-storage size by removing .srodata section
from it. It initially was included in TLS section by mistake.
The issue was found when stack size increased after building applications
with GCC-11.1 compiler. Stack size became bigger because some new data
appeared in .srodata. See more details here:

The previously used splits between memory allocated for ROM code,
2nd stage bootloader and the app were somewhat safe and conservative.
This resulted in some space being unavailable for static allocation
in the app.
This commit increases the space available for static allocation to the
maximum possible amount.
1. Some of the ROM code static allocation is only used in UART/USB/SPI
download modes. This region ("shared buffers") has been placed at
the lower end of ROM memory area, to be reusable in flash boot
mode. The 2nd stage bootloader linker script is modified to "pack"
all sections exactly up to the end but with roughly 8K margin between
startup stacks.
2. Instead of calculating the sections placement and hardcoding the
addresses in the LD script again, rewrite it to calculate the
start address of each memory region automatically based on the
logic above.
3. Adjust the app memory layout (SRAM_IRAM_END) accordingly,
increasing the space available for static allocation.
Overall these changes increase the space available for static
allocation by about 78kB.
The downside of these changes is that the 2nd stage bootloader .data
segment is now directly adjacent to the startup stack on the PRO CPU.
Previously, there was effectively about 78kB of extra stack space for
the PRO CPU, before the stack would run into the data segment.
This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.
Moved the following kconfig options out of the target component:
* CONFIG_ESP*_DEFAULT_CPU_FREQ* -> esp_system
* ESP*_REV_MIN -> esp_hw_support
* ESP*_TIME_SYSCALL -> newlib
* ESP*_RTC_* -> esp_hw_support
Where applicable these target specific konfig names were merged into
a single common config, e.g;
CONFIG_ESP*_DEFAULT_CPU_FREQ -> CONFIG_ESP_DEFAULT_CPU_FREQ_MHZ
