OTA Bootloader (rboot) source module and support files.
rboot is an open source bootloader by Richard Burton:
https://github.com/raburton/rboot
Can be used to build an esp-open-rtos compatible rboot bootloader. Run 'make bootloader' in this directory to compile a new bootloader.
Compiling a new bootloader is optional, there's a prebuilt one in the "firmware_prebuilt" directory that will be used if no new bootloader was compiled.
It is also possible to use rboot from upstream verbatim, but *ensure that the `RBOOT_BIG_FLASH` option is enabled or images in slots other than 0 won't work correctly.
See the contents of the 'rboot' directory for more information on rboot.

aligned reads. It's up to the user of this attribute to ensure this.
Use the IRAM attribute for functions which are called when the
flash may not be available (for example during NMI exceptions), or
for functions which are called very frequently and need high
performance.
Usage example:

/** Internal Espressif SDK "PHY info" data structure
The data structure (sdk_phy_info_t) is used to configure the
ESP8266 PHY layer via the SDK. The fields here are not written
directly to hardware, the SDK code (mostly in libphy) parses this
structure and configures the hardware.
The structure loaded at reset time from a flash configuration
sector (see read_saved_phy_info()) (Espressif's SDK sources this
from a file "esp_init_data_default.bin"). If no valid structure is
found in the flash config sector then the SDK loads default values
(see get_default_phy_info()). It is possible to implement a custom
get_default_phy_info() to change the PHY default settings (see the
'version' field below).
@note It is possible that the SDK will quietly write a new
configuration sector to flash itself following internal
calibration, etc. However this does not seem to happen, you need to
flash it explicitly if you want it stored there.
@note Most of what is below is unconfirmed, except where a @note
says that it has been confirmed to work as expected. Please
consider submitting notes if you find behaviour here that works or
doesn't work as expected.
Information on the meaning/offset of fields comes from Espressif's
flash download tool, which uses an Excel spreadsheet (in the
init_data directory of the ZIP file) to configure and a Python
script to convert an esp_init_data_custom.bin file to flash:
http://bbs.espressif.com/viewtopic.php?f=5&t=433
Many fields remain undocumented (& disassembly of libphy suggests
that some documented fields supported undocumented values.)
A few additional notes about the phy_info fields can be found
in the ESP Arduino ESP8266 phy_init_data structure (however most of
that content is verbatim from Espressif's spreadsheet):
