Subject: [PATCH V1] ARM: dts: tegra: Modify pcie memory space size
Date: Thu, 20 Jun 2013 12:44:51 +0530 [thread overview]
Message-ID: <1371712491-31070-1-git-send-email-jagarwal@nvidia.com> (raw)
- decrease non-prefetch memory size to 128 MB
- increase prefetch memory size to 384 MB
- above change is done because most pcie devices
prefetch memory size requirement is quite higher
compared to non-prefetch memory space.
