Subject: [PATCH v3 3/3] ARM: dts: tegra: Add support for 256 MB Colibri-T20 (plus such board on Iris)
Colibri-T20 can come in 256 MB RAM (with 512 MB NAND) or 512 MB RAM
(with 1024 MB NAND) flavors. Add support for the 256 MB version on Iris
evaluation board.
Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>
---
Changes since v2:
1. Do not add new compatible but use everywhere existing
"toradex,colibri_t20-512" (suggested by Rob).
Changes since v1:
1. Fix memory size in tegra20-colibri-256.dtsi (was working fine because
my bootloader uses mem= argument).
