+# GCC uses -G 0 -mabicalls -fpic as default. We don't want PIC in the kernel
+# code since it only slows down the whole thing. At some point we might make
+# use of global pointer optimizations but their use of $28 conflicts with
+# the current pointer optimization.
+#
+# The DECStation requires an ECOFF kernel for remote booting, other MIPS
+# machines may also. Since BFD is incredibly buggy with respect to
+# crossformat linking we rely on the elf2ecoff tool for format conversion.

+# On the other hand, we want PIC in the U-Boot code to relocate it from ROM
