-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
