-  FPU Configuration Options
-  -------------------------
-
-  There are two version of the FPU support built into the LPC17xx port.
-
-  1. Lazy Floating Point Register Save.
-
-    This is an untested implementation that saves and restores FPU registers
-    only on context switches.  This means: (1) floating point registers are
-    not stored on each context switch and, hence, possibly better interrupt
-    performance.  But, (2) since floating point registers are not saved,
-    you cannot use floating point operations within interrupt handlers.
-
-    This logic can be enabled by simply adding the following to your .config
-    file:
-
-    CONFIG_ARCH_FPU=y
-
-  2. Non-Lazy Floating Point Register Save
-
-    Mike Smith has contributed an extensive re-write of the ARMv7-M exception
-    handling logic. This includes verified support for the FPU.  These changes
-    have not yet been incorporated into the mainline and are still considered
-    experimental.  These FPU logic can be enabled with:
-
-    CONFIG_ARCH_FPU=y
-    CONFIG_ARMV7M_CMNVECTOR=y
-
-    You will probably also changes to the ld.script in if this option is selected.
-    This should work:
-
-    -ENTRY(_stext)
-    +ENTRY(__start)         /* Treat __start as the anchor for dead code stripping */
-    +EXTERN(_vectors)       /* Force the vectors to be included in the output */
