2019-02-15mtd: rawnand: gpmi: fix MX28 bus master lockup problemMartin Kepplinger
commit d5d27fd9826b59979b184ec288e4812abac0e988 upstream. Disable BCH soft reset according to MX23 erratum #2847 ("BCH soft reset may cause bus master lock up") for MX28 too. It has the same problem. Observed problem: once per 100,000+ MX28 reboots NAND read failed on DMA timeout errors: [ 1.770823] UBI: attaching mtd3 to ubi0 [ 2.768088] gpmi_nand: DMA timeout, last DMA :1 [ 3.958087] gpmi_nand: BCH timeout, last DMA :1 [ 4.156033] gpmi_nand: Error in ECC-based read: -110 [ 4.161136] UBI warning: ubi_io_read: error -110 while reading 64 bytes from PEB 0:0, read only 0 bytes, retry [ 4.171283] step 1 error [ 4.173846] gpmi_nand: Chip: 0, Error -1 Without BCH soft reset we successfully executed 1,000,000 MX28 reboots. I have a quote from NXP regarding this problem, from July 18th 2016: "As the i.MX23 and i.MX28 are of the same generation, they share many characteristics. Unfortunately, also the erratas may be shared. In case of the documented erratas and the workarounds, you can also apply the workaround solution of one device on the other one. This have been reported, but I’m afraid that there are not an estimated date for updating the Errata documents. Please accept our apologies for any inconveniences this may cause."

commit 2a9d92fb3a1282a4659f1bb6d5684018846537b7 upstream. I ran into a link-time error with the atmel-quadspi driver on the EBSA110 platform: drivers/mtd/built-in.o: In function `atmel_qspi_run_command': :(.text+0x1ee3c): undefined reference to `_memcpy_toio' :(.text+0x1ee48): undefined reference to `_memcpy_fromio' The problem is that _memcpy_toio/_memcpy_fromio are not available on that platform, and we have to prevent building the driver there. In case we want to backport this to older kernels: between linux-4.8 and linux-4.20, the Kconfig entry was in drivers/mtd/spi-nor/Kconfig but had the same problem.

2018-12-24mtd: gpmi: fsl,legacy-bch-geometry independent of nand-on-flash-bbtMax Krummenacher
The device tree property fsl,legacy-bch-geometry was only evaluated when nand-on-flash-bbt was also defined. This looks wrong. In mainline (as of 4.12) fsl,legacy-bch-geometry doesn't exist, its functionality seems to be taken over by the fsl,use-minimum-ecc property and it is used independent of nand-on-flash-bbt.

2018-11-21mtd: docg3: don't set conflicting BCH_CONST_PARAMS optionArnd Bergmann
commit be2e1c9dcf76886a83fb1c433a316e26d4ca2550 upstream. I noticed during the creation of another bugfix that the BCH_CONST_PARAMS option that is set by DOCG3 breaks setting variable parameters for any other users of the BCH library code. The only other user we have today is the MTD_NAND software BCH implementation (most flash controllers use hardware BCH these days and are not affected). I considered removing BCH_CONST_PARAMS entirely because of the inherent conflict, but according to the description in lib/bch.c there is a significant performance benefit in keeping it. To avoid the immediate problem of the conflict between MTD_NAND_BCH and DOCG3, this only sets the constant parameters if MTD_NAND_BCH is disabled, which should fix the problem for all cases that are affected. This should also work for all stable kernels. Note that there is only one machine that actually seems to use the DOCG3 driver (arch/arm/mach-pxa/mioa701.c), so most users should have the driver disabled, but it almost certainly shows up if we wanted to test random kernels on machines that use software BCH in MTD.

[ Upstream commit 6c6bc9ea84d0008024606bf5ba10519e20d851bf ] The first checks in mtdchar_read() and mtdchar_write() attempt to limit `count` such that `*ppos + count <= mtd->size`. However, they ignore the possibility of `*ppos > mtd->size`, allowing the calculation of `count` to wrap around. `mtdchar_lseek()` prevents seeking beyond mtd->size, but the pread/pwrite syscalls bypass this. I haven't found any codepath on which this actually causes dangerous behavior, but it seems like a sensible change anyway.

2018-08-24ENGR00279980 ubi: attach: do not return -EINVAL if the mtd->numeraseregions is 1Huang Shijie
If the master mtd does not have any slave mtd partitions, and its numeraseregions is one(only has one erease block), and we attach the master mtd with : ubiattach -m 0 -d 0 We will meet the error: ------------------------------------------------------- root@freescale ~$ ubiattach /dev/ubi_ctrl -m 0 -d 0 UBI: attaching mtd0 to ubi0 UBI error: io_init: multiple regions, not implemented ubiattach: error!: cannot attach mtd0 error 22 (Invalid argument) ------------------------------------------------------- In fact, if there is only one "erase block", we should not prevent the attach. This patch fixes it.
