[U-Boot] [PATCH v3 5/7] tegra: fdt: Add NAND definitions to fdt

Simon Glass sjg at chromium.org
Tue Apr 17 20:50:12 CEST 2012


Add a flash node to handle the NAND, including memory timings and
page / block size information.

Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v2:
- Update NAND binding to add "nvidia," prefix

Changes in v3:
- Add reg property for unit address (should be used for chip select)
- Update fdt binding to make everything Nvidia-specific
