I wanted to choose boot location for P2040. Does P2040 supports GPCM 16 bit NOR boot?

Yes, P2040 supports GPCM 16 bit NOR boot. It can be done by configuring 4 bits (bit 192 to 195) of RCW source location to 1101.

If I use NOR FLASH as boot device, can NOR FLASH be used as RCW storage device? Do I need an extra SPI flash is required or not?

Yes, you can use NOR flash and the options are 0x1100 and 0x1101 (listed in the table 4-26 in P2040 Reference Manual).

Does P2040 support to boot from SPI flash?
