T1022 SPI Boot

We are working on a custom board with a T1022 processor and would like to boot from SPI flash memory.


We require 128MB of memory but the processor only supports 24-bit addressing when booting from SPI restricting addressable space to 16MB.


Is it possible to load the boot data using 24-bit addressing and then re-configure the SPI interface to use 32-bit addressing after so we can use 128MB of memory?
