From c39f44dc6f5ae843d5def511f6e71d4b012dc598 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Mon, 31 Jan 2011 22:18:47 -0600 Subject: [PATCH] powerpc/8xxx: Refactor fsl_ddr_get_spd into common code from board Move fsl_ddr_get_spd into common mpc8xxx/ddr/main.c as most boards pretty much do the same thing. The only variations are in how many controllers or DIMMs per controller exist. To make this work we standardize on the names of the SPD_EEPROM_ADDRESS defines based on the use case of the board. We allow boards to override get_spd to either do board specific fixups to the SPD data or deal with any unique behavior of how the SPD eeproms are wired up.
