Subject: [PATCH v1 1/2] dt-bindings: mtd: amlogic,meson-nand: support fields for boot ROM code

Boot ROM code on Meson requires that some pages on NAND must be written
in special mode: "short" ECC mode where each block is 384 bytes and
scrambling mode is on. Such pages located with the specified interval
within specified offset. Both interval and offset are located in the
device tree and used by driver if 'nand-is-boot-medium' is set for
NAND chip.
