ARM: dts: Add basic support for isee igepv5
With omap5-board-common.dtsi, we can now easily add support for various omap5 board variants. Let's add minimal support for isee igepv5. So far I've tested that basic things work, such as serial, USB Ethernet, HDMI and WLAN. Note that like omap5-uevm, these boards seem to need to reserve 16MB for a trap section as in commit 03178c66d289 ("ARM: dts: omap5-evm: Update available memory to 2032 MB") and also noted in a u-boot commit at http://marc.info/?l=u-boot&m=134376852603255 and also at http://patchwork.ozlabs.org/patch/159881/. Not sure why this is not needed for omap5-cm-t54.dts, maybe because of different u-boot configuration. Signed-off-by: Tony Lindgren <tony@atomide.com>
