We fixed some flash bugs in bootloader, but for the users used the old
vrsion bootloader, they can not fix these bugs via OTA, the solution is
add these updates in app startup.
These updates include:
1. SPI flash gpio matrix and drive strength configuration
2. SPI flash clock configuration
3. SPI flash read dummy configuration
4. SPI flash cs timing configuration
5. Update flash id of g_rom_flashchip
When flash work in DIO Mode, in order to ensure the fast read mode of flash
is a fixed value, we merged the mode bits into address part, and the fast
read mode value is 0 (the default value).
Fixed the case when the first part of log was missed
this was happened when:
* CONFIG_CONSOLE_UART_CUSTOM option is selected (UART1)
* The selected CONSOLE_UART port is used also for the console component
* in code esp_restart() or abort() functions were called.
In the situation when bootloader was compiled for 240MHz, and app was
compiled for 160MHz, and the chip is a revision 0 chip, the
bootloader will assume that the application has also been running at
240MHz. This will cause the chip to lock up later. Modify this to use
a run time check of DPORT_CPUPERIOD_SEL, which indicates which of the
PLL frequencies was used.

Bootloader used to calculate the number of cache pages assuming that
load address was aligned, while in reality load address for DROM and
IROM was offset by 0x20 bytes from the start of 64kB page. This
caused the bootloader to map one less page if the size of the image
was 0x4..0x1c less than a multiple of 64kB.
Reported in https://esp32.com/viewtopic.php?f=13&t=6952.
If zero-overhead loop buffer is enabled, under certain rare conditions
when executing a zero-overhead loop, the CPU may attempt to execute an invalid instruction. Work around by disabling the buffer.
Allows OTA updates to be secured via signature checks, without requiring the overhead or complexity
of a full secure boot implementation.
Uses same signing mechanisms (build system and/or espsecure.py as Secure Boot).
Requires:
* [ ] More testing
* [ ] Documentation
If we have the partition table without any ota_apps but in ota_data have
valide entry, in this case we get an error(hang). This commit fix this
case. If bs->app_count is zero when selecting the factory app.

Because address space is mapped in 64KB pages, it was possible for unauthenticated data after the
app .bin to become mapped into the flash cache address space.
This problem is solved by 2 changes:
* "esptool elf2image --secure-pad" will pad the image so that the signature block ends close to the
64KB boundary. Due to alignment constraints it will be 12 bytes too short after signing (but
with flash encryption, these 12 bytes are still encrypted as part of the last block and can't be
arbitrarily changed).
* By default, secure boot now requires all app partitions to be a multiple of 64KB in size.
Moved useful functions from wrapped assert functions, because option `CONFIG_OPTIMIZATION_ASSERTIONS_DISABLED=y` will remove this functions.

IDF had two defines ESP_PARTITION_TABLE_OFFSET and ESP_PARTITION_TABLE_ADDR. They were the same and equal by 0x8000.
A define ESP_PARTITION_TABLE_ADDR was removed from IDF.
A define ESP_PARTITION_TABLE_OFFSET depends on option CONFIG_PARTITION_TABLE_OFFSET in Kconfig.
Now using only #define ESP_PARTITION_TABLE_OFFSET CONFIG_PARTITION_TABLE_OFFSET
Allows you to move the partition table, it gives more space for the bootloader.
Added a new utility - parttool.py. This utility can search for the offset and/or size of the partitions by name and type/subtype. Use for getting APP_OFFSET and PHY_DATA_OFFSET.
The linker(esp32.bootloader.ld) made changes that allow you to write a custom bootloader code more.

Added feature:
- reset firmware to Factory app.(by long pressing of the button)
- boot Test app. (by long pressing of the button)
- Added feature erase data partitions from factory reset.

The following mbedTLS APIs have been deprecated and replaced with the
new ones which return error codes:
mbedtls_shaX_starts -> mbedtls_shaX_starts_ret
mbedtls_shaX_update -> mbedtls_shaX_update_ret
mbedtls_shaX_finish -> mbedtls_shaX_finish_ret
mbedtls_shaX_process -> mbedtls_shaX_internal_process
Update hardware implementations of SHA functions, and other IDF
components which used above functions, to use new versions.
* Philosophical: "explicit is better than implicit".
* Practical: Allows useful errors if invalid directories given in components as the defaults aren't
always used. Also trims the -I path from a number of components that have no actual include
directory.
* Simplifies knowing which components will be header-only and which won't
