28 bool "Add a Remote Management Unit (RMU) binary"
30 Select this option to add a Remote Management Unit (RMU) binary
31 to the resulting U-Boot image. It is a data block (up to 64K) of
32 machine-specific code which must be put in the flash for the RMU
33 within the Quark SoC processor to access when powered up before
34 system BIOS is executed.
37 string "Remote Management Unit (RMU) binary filename"
41 The filename of the file to use as Remote Management Unit (RMU)
42 binary in the board directory.
45 hex "Remote Management Unit (RMU) binary location"
49 The location of the RMU binary is determined by a strap. It must be
50 put in flash at a location matching the strap-determined base address.
52 The default base address of 0xfff00000 indicates that the binary must
53 be located at offset 0 from the beginning of a 1MB flash device.
