[U-Boot] [PATCH v2] vexpress64: use 2nd DRAM bank only on juno
by Ryan Harkin 13 Nov '15

13 Nov '15

This patch makes the 2nd DRAM bank available on Juno only and not on other vexpress64 targets, eg. the FVP models. The commit below added a 2nd bank of NOR flash for Juno, but also for all vexpress64 targets: commit 2d0cee1ca2b9d977fa3214896bb2e30cfec77059 Author: Liviu Dudau <Liviu.Dudau(a)foss.arm.com> Date: Mon Oct 19 11:08:31 2015 +0100 vexpress64: Juno: Declare all 8GB of RAM and make them visible to the kernel.

[U-Boot] [PATCH v2] fdt_support: Check for bank size before updating memory node
by Lokesh Vutla 13 Nov '15

13 Nov '15

In case if one of the bank that is passed is of size zero, then u-boot will be updating memory node with a bank of size zero. There is no need to update memory node if size is zero, so check for bank size before updating.
