/* With this Intel bootloader only the hardware variant and device

*
* The firmware filename is ibt-<hw_variant>-<dev_revid>.sfi.
*
* Currently the supported hardware variants are:
* 11 (0x0b) for iBT 3.0 (LnP/SfP)
+ * 12 (0x0c) for iBT 3.5 (WsP)
+ *
+ * For ThP/JfP and for future SKU's, the FW name varies based on HW
+ * variant, HW revision and FW revision, as these are dependent on CNVi
+ * and RF Combination.
+ *
+ * 18 (0x12) for iBT3.5 (ThP/JfP)
+ *
+ * The firmware file name for these will be
+ * ibt-<hw_variant>-<hw_revision>-<fw_revision>.sfi.
