From 329031fdedb332f75b2d3ce6c165bb62d9631600 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Fri, 19 Aug 2016 16:35:22 -0700 Subject: gru: Make SDRAM parameters individual struct files in CBFS This patch changes Gru SDRAM parameters from structures that just get compiled into the romstage to individual CBFS files. This allows us to only load the parameter set we need for the board we're booting from flash, which reduces our boot time and the SRAM memory footprint required to hold the romstage. TEST=Booted Kevin.
