FlexSPI_A QSPI boot using secondary pinmux

I am using a 1021 device and want to use a 'standard' FlexSPI QSPI as a boot device, but I want to configure it as FlexsSPI_A onto GPIO_AD_B1_00 .. 05 rather than the more conventional (based on EVK & other designs) GPIO_SD_B1_06 .. 11 pinning.

 

Is there anything special I need to do it order to enable this, or is it just a case of setting BOOT_CFG2[2:0] to 111b (From table 8-9 of the reference manual and Table 71 of the Datasheet)? I assume this means I cannot use a QSPI device that supports 0x4B read, only 0x3B read?

 

I don't want to go spin a board and then find I can't boot it for some reason!

DAVE
