9240bbb708 esp32: remove ROM functions redefined in IDF from LD script
In some cases, linker could choose to use ROM functions instead of the
ones defined in IDF.
For functions used in ROM stub table, this would lead to infinite
recursion when the corresponding function was called from ROM.
For crypto functions, some of these were modified in IDF, and
incompatible with ROM counterparts.

4a987dacca bootloader: keep bootloader_common code to retention region
It is possible to utilize some of the routines related to otadata
partition validation, after firmware image is downloaded to RAM. Hence
these routines should be part of app cpu cache, so that they do not
get overwritten by firmware.

b364f23e17 secure boot: Support secure boot signatures without hardware secure boot
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

f0d74b1c64 bootloader: Ensure bootloader never returns to caller
* Fixes some "noreturn" functions in bootloader utils which did return (causing fatal CPU
  exceptions).
* Marks bootloader entry as "noreturn", preventing "user code done" from stalling boot
  Partial fix for https://github.com/espressif/esp-idf/issues/1814 TW20016
  (Comprehensive fix for this issue will be enabling WDT during bootloader, coming shortly.)

57b601ab7f secure boot: Pad to avoid data after the signature mapping into the address space
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.

5551b3f616 bootloader: move iram_seg 1k up to have better looking idf_monitor output
When 2nd stage bootloader loads the ROM bootloader, it prints a
message similar to "entry 0x40080xxx", which idf_monitor decodes
(using application ELF file) as one of the reset vectors (xxx is <
400h). This moves the iram_seg of bootloader 1k up to prevent overlap
of bootloader .text and application vectors, making the output look
nicer. There is still a chance that the entry point decodes as some
symbol in application ELF file, but at least it won't have
"Exception" in its name.

3e0ac4db79 partition_table: Expanding the space under the bootloader
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.

This commit adds support for CPU max freqeuency rating
bits in CPU. Bootloader will now print an error if attempting
to 160MHz rated ESP32 at 240MHz.

EFUSE_CHIP_VER_RESERVE has been replaced by the
frequency rating bits. Dependancies on EFUSE_CHIP_VER_RESERVE
have been changed to use EFUSE_CHIP_VER_PKG
