From f2717b47eac74fe262d89c6d8f6bb5a047a77229 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Tue, 22 Nov 2011 09:21:25 -0600 Subject: powerpc/85xx: clean up and document the QE/FMAN microcode macros Several macros are used to identify and locate the microcode binary image that U-boot needs to upload to the QE or Fman. Both the QE and the Fman use the QE Firmware binary format to package their respective microcode data, which is why the same macros are used for both. A given SOC will only have a QE or an Fman, so this is safe. Unfortunately, the current macro definition and usage has inconsistencies. For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address of NAND. There's no way to know by looking at a variable how it's supposed to be used. In the future, the code which uploads QE firmware and Fman firmware will be merged.
