From 52acef175e42374d463214427678e3e7828960c3 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Wed, 8 Aug 2018 12:46:18 +0200 Subject: soc/cavium/cn81xx: Fix minor things * Move cbmem.c to cn81xx folder * Store CBMEM below 4 GiB * Make sure CBMEM doesn't overlap with ATF scratchpad * Fix ATF scratchpad not marked as reserved due to wrong calculation * The scratchpad is the last 1 MiB at the end of DRAM. Tested on Cavium CN81xx EVB: The ATF scratchpad is now marked reserved and the configuration tables are located below 4 GiB. Linux still boots.
