Hardware design considerations for bootloader in a STM32F103 board

I'm designing a hardware for STM32F103 and I want to be able to upgrade the firmware through GPRS later. I've already implemented a 128MByte NAND flash in the design but after a while I figured that NAND flash is probably not a source for booloader and according to documents they are USB, SPI, UART and ... so I figured to put a W25Q32 (32MBit SPI flash) as a boot source. Is that correct and enough? Or more hardware considerations have to be taken care in this phase?
