Review comment:
       Why don't we add this toolchain to arch/mips/src/mips32/Toolchain.defs?

+=================
+
+  CAUTION:
+
+  Currently the pre-installed bootloader of the chipKIT Wi-FIRE board
+  is not supported in this NuttX configuration. Doing the following
+  steps will erase the factory installed bootloader in the Flash
+  memory! If you are going to recover the bootloader later on your
+  chipKIT Wi-FIRE board, the original chipKIT bootloader can be found here:
+  https://reference.digilentinc.com/_media/chipkit_wifire/chipkit-wifire-v01000303.zip

Review comment:
       Can't we reserve the bootloader region in the linker script?
