How can I test this entire Boot loader receiving application software over SPI for STM32F207 X and Y version chip , and how to check if my IC is STM32F207 X and Y version .
I am working with STM32F207 as making it as Slave SPI and using another Master SPI microcontroller to update STM32F207 Application software using inbuilt bootloader of STM32F207
For this I need to have to check if my STM32F207 is version X and Y and to use inbuilt Boot Loader and update application over SPI as mentioned below
STM32F2xxxx devices bootloader
Two bootloader versions are available on STM32F2xxxx devices:
• V2.x supporting USART1 and USART3
This version is embedded in STM32F2xxxx devices revision B.
• V3.x supporting USART1, USART3, CAN2 and DFU (USB FS Device)
This version is embedded in STM32F2xxxx devices revision X and Y.
PAGE 65 of the following pdf will explain the same .

The version is marked on the top of the chip, and also readable via DBGMCU->IDCODE the Reference Manual should breakdown the chip versions and how they are decoded.
The System Loader can report its version number.
