+Subject: mtd: eLBC NAND: fix subpage write support
+
+From: Pekon Gupta <pekon@ti.com>
+
+commit f034d87def51f026b735d1e2877e9387011b2ba3 upstream.
+
+As subpage write is enabled by default for all drivers, nand_write_subpage_hwecc
+causes a crash if the driver did not register ecc->hwctl or ecc->calculate.
+This behavior was introduced in
+ commit 837a6ba4f3b6d23026674e6af6b6849a4634fff9
+ "mtd: nand: subpage write support for hardware based ECC schemes".
+
+This fixes a crash by emulating subpage write support by padding sub-page data
+with 0xff on either sides to make it full page compatible.

+Subject: mtd: nand: omap: fix BCHx ecc.correct to return detected bit-flips in erased-page
+
+From: pekon gupta <pekon@ti.com>
+
+commit f306e8c3b667632952f1a4a74ffb910bbc06255f upstream.
+
+fixes: commit 62116e5171e00f85a8d53f76e45b84423c89ff34
+ mtd: nand: omap2: Support for hardware BCH error correction.
+
+In omap_elm_correct_data(), if bitflip_count in an erased-page is within the
+correctable limit (< ecc.strength), then it is not indicated back to the caller
+ecc->read_page().
+
+This mis-guides upper layers like MTD and UBIFS layer to assume erased-page as
+perfectly clean and use it for writing even if actual bitflip_count was
+dangerously high (bitflip_count > mtd->bitflip_threshold).
+
+This patch fixes this above issue, by returning 'stats' to caller
+ecc->read_page() under all scenarios.
