+From: Luis Araneda <luaraneda@gmail.com>
+Date: Sun, 22 Jul 2018 02:52:41 -0400
+Subject: [U-Boot] [RFC PATCH] arm: zynq: read mac address from SPI flash memory
+
+Implement a method for reading the MAC address from an
+SPI flash memory.
+In particular, this method is used by the Zybo Z7 board
+to read the MAC address from the OTP region in the SPI NOR
+memory
+
+Signed-off-by: Luis Araneda <luaraneda@gmail.com>
+---
+As of 2018-08-23, this patch has been sent to U-Boot's mailing list
+and is being reviewed. Some changes on the implementation are expected,
+but the functionality should not change
