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.
