+
+W25N01GV is a single die version of the already supported
+W25M02GV with half the capacity. Everything else is the
+same so introduce support for W25N01GV.
+
+Datasheet:http://www.winbond.com/resource-files/w25n01gv%20revl%20050918%20unsecured.pdf
+
+Tested on 8devices Jalapeno dev board under OpenWrt running 4.19-rc5.

+IMPORTANT NOTE
+==============
+
+The content of this patch has been adapted for Linux 4.19
+
+Changes were made in Linux 5.x to add the bad-block limit
+to the metadata available to the driver, adding a parameter
+
+NAND_MEMORG(1, 2048, 128, 64, 1024, 20, 1, 1, 1),
+ ^- New bad-block limit
+
+This patch omits that parameter from the upstream patch
+for compatibility with the Linux 4.19 driver.

+Subject: [PATCH 3/3] mtd: spinand: Add support for GigaDevice GD5F1GQ4UFxxG
+
+The GigaDevice GD5F1GQ4UFxxG SPI NAND is in current production devices
+and, while it has the same logical layout as the E-series devices,
+it differs in the SPI interfacing in significant ways.
+
+This support is contingent on previous commits to:
+
+ * Add support for two-byte device IDs
+ * Define macros for page-read ops with three-byte addresses
+

-W25N01GV is a single die version of the already supported
-W25M02GV with half the capacity. Everything else is the
