+Subject: [PATCH 1/2] chromium: Check for __ARM_FP & 2 before using __fp16
+
+The __fp16 type denotes half-precision (16-bit) floating-point.
+The recommended way to test for this hardware support is to test bit 1 in __ARM_FP
+and
+If 16-bit floating-point is available, one of __ARM_FP16_FORMAT_IEEE and
+__ARM_FP16_FORMAT_ALTERNATIVE will be defined to indicate the format in use
+
+Upstream-Status: Pending
