Detailed Description

Structure containing rBoot configuration.

Note: ROM addresses must be multiples of 0x1000 (flash sector aligned). Without BOOT_BIG_FLASH only the first 8Mbit (1MB) of the chip will be memory mapped so ROM slots containing .irom0.text sections must remain below 0x100000. Slots beyond this will only be accessible via spi read calls, so use these for stored resources, not code. With BOOT_BIG_FLASH the flash will be mapped in chunks of 8MBit (1MB), so ROMs can be anywhere, but must not straddle two 8MBit (1MB) blocks.
