+Freescale QE/FMAN Firmware Support:
+-----------------------------------
+
+The Freescale QUICCEngine (QE) and Frame Manager (FMAN) both support the
+loading of "firmware", which is encoded in the QE firmware binary format.
+This firmware often needs to be loaded during U-Boot booting, so macros
+are used to identify the storage device (NOR flash, SPI, etc) and the address
+within that device.
+
+- CONFIG_SYS_QE_FMAN_FW_ADDR
+       The address in the storage device where the firmware is located.  The
+       meaning of this address depends on which CONFIG_SYS_QE_FW_IN_xxx macro
+       is also specified.
+
+- CONFIG_SYS_QE_FMAN_FW_LENGTH
+       The maximum possible size of the firmware.  The firmware binary format
+       has a field that specifies the actual size of the firmware, but it
+       might not be possible to read any part of the firmware unless some
+       local storage is allocated to hold the entire firmware first.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_NOR
+       Specifies that QE/FMAN firmware is located in NOR flash, mapped as
+       normal addressable memory via the LBC.  CONFIG_SYS_FMAN_FW_ADDR is the
+       virtual address in NOR flash.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_NAND
+       Specifies that QE/FMAN firmware is located in NAND flash.
+       CONFIG_SYS_FMAN_FW_ADDR is the offset within NAND flash.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_MMC
+       Specifies that QE/FMAN firmware is located on the primary SD/MMC
+       device.  CONFIG_SYS_FMAN_FW_ADDR is the byte offset on that device.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_SPIFLASH
+       Specifies that QE/FMAN firmware is located on the primary SPI
+       device.  CONFIG_SYS_FMAN_FW_ADDR is the byte offset on that device.
