-Subject: [PATCH] mtd: cfi_cmdset_0002: AMD chip 0x2201 - write words
-
-Buffer writes do not work with AMD chip 0x2201. The chip in question
-is a AMD/Spansion/Cypress Semiconductor S29GL256N and datasheet [1]
-talks about writing buffers being possible. While waiting for a neater
-solution resort to writing word-sized chunks only.
-
-Without the patch kernel logs will be flooded with entries like below:
-
-jffs2_scan_eraseblock(): End of filesystem marker found at 0x0
-jffs2_build_filesystem(): unlocking the mtd device...
-done.
-jffs2_build_filesystem(): erasing all blocks after the end marker...
