Subject: [PATCH v4 03/12] dt-bindings: mtd: brcmnand: Add ecc strap property

Add brcm,nand-ecc-use-strap to get ecc and spare area size settings from
board boot strap for broadband board designs because they do not specify
ecc setting in dts but rather using the strap setting.

Signed-off-by: William Zhang <william.zhang@...adcom.com>

Changes in v4:
- Move ecc strap property to this separate patch and remove some
