62b0d51c02 Enable secure boot only after encrypting flash
This prevents a device from being bricked in case when both secure boot & flash encryption are enabled and encryption gets interrupted during first boot. After interruption, all partitions on the device need to be reflashed (including the bootloader).

List of changes:
* Secure boot key generation and bootloader digest generation logic, implemented inside function esp_secure_boot_permanently_enable(), has been pulled out into new API esp_secure_boot_generate_digest(). The enabling of R/W protection of secure boot key on EFUSE still happens inside esp_secure_boot_permanently_enable()
* Now esp_secure_boot_permanently_enable() is called only after flash encryption process completes
* esp_secure_boot_generate_digest() is called before flash encryption process starts

178e5b25e6 bootloader: check previously used clock frequency at run time
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.

Closes https://github.com/espressif/esp-idf/issues/2731.

96d0f7f5e2 bootloader: account for load address when mapping cache pages
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.

3b9cb25fe1 esp32: Add firmware version to app
Added a new structure esp_app_desc_t. It has info about firmware:
version, secure_version, project_name, time/date build and IDF version.
Added the ability to add a custom structure with a description of the firmware.

The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t.

app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe).

Add API to get app_desc from partition.

a1f809fcc5 bootloader: provide implementation of abort
ROM definition of `abort` was removed in 9240bbb. The old definition
resulted in a panic due to a jump to a null pointer (abort member in
ROM stub table was zero). The new definition triggers a debug
exception if JTAG is connected, or goes into an infinite loop to be
reset by the WDT.

22b840f3df bootloader: don’t reload RTC_FAST DRAM after deep sleep
When CONFIG_ESP32_RTCDATA_IN_FAST_MEM is enabled, RTC data is placed
into RTC_FAST memory region, viewed from the data bus. However the
bootloader was missing a check that this region should not be
overwritten after deep sleep, which caused .rtc.bss segment to loose
its contents after wakeup.

117c79eae5 app_update: Add API for getting sha256_of_partition
Added bootloader_common_get_sha256_of_partition() and esp_partition_get_sha256() - get or calculate SHA-256
digest for app and data partitions.
Added bootloader_sha256_hex_to_str() - helps to print SHA-256 digest
Added esp_partition_check_identity() - compares two partitions by SHA-256 digest

Refactoring a function esp_image_load() in bootloader space to esp_image_verify() and
bootloader_load_image(). Old name function esp_image_load is deprecated
and will remove in V4.0 version.
