From 9cbc90a1f6e197258ed47bc44016640f2b1e5a31 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Mon, 25 Jul 2016 11:30:43 -0500 Subject: soc/nvidia/tegra124: remove cache_policiy option All mainboards (nyans) utilizing the cache_policy option has it set to DCACHE_WRITETHROUGH. This option is for setting the framebuffer's cache attribute. However, this option is reliant on an architecture-specific enumeration. Just remove the option and use DCACHE_WRITETHROUGH across the board. If someone wants to reconfigure it at a later date one can introduce a non-architecture specific option.
