44 In this document, the term 'microcode' refers to the sequence of 32-bit
45 integers that compose the actual QE microcode.
47 The term 'firmware' refers to a binary blob that contains the microcode as

60 The QE architecture allows for only one microcode present in I-RAM for each
61 RISC processor.  To replace any current microcode, a full QE reset (which
62 disables the microcode) must be performed first.
64 QE microcode is uploaded using the following procedure:
66 1) The microcode is placed into I-RAM at a specific location, using the

169 QE microcode from Freescale is typically provided as a header file.  This
170 header file contains macros that define the microcode binary itself as well as
171 some other data used in uploading that microcode.  The format of these files
