2019-06-28mtd: spinand: read returns badly if the last page has bitflipsliaoweixiong
In case of the last page containing bitflips (ret > 0), spinand_mtd_read() will return that number of bitflips for the last page while it should instead return max_bitflips like it does when the last page read returns with 0.

2019-06-27mtd: rawnand: gpmi: Implement exec_opSascha Hauer
The gpmi driver performance suffers from NAND operations being split in multiple small DMA transfers. This has been forced by the NAND layer in the former days, but now with exec_op we can use the controller as intended. With this patch gpmi_nfc_exec_op becomes the main entry point to NAND operations. Here all instructions are collected and chained as separate DMA transfers. In the end whole chain is fired and waited to be finished. gpmi_nfc_exec_op only does the hardware operations, bad block marker swapping and buffer scrambling is done by the callers. It's worth noting that the nand_*_op functions always take the buffer lengths for the data that the NAND chip actually transfers. When doing BCH we have to calculate the net data size from the raw data size in some places. This patch has been tested with 2048/64 and 2048/128 byte NAND on i.MX6q. mtd_oobtest, mtd_subpagetest and mtd_speedtest run without errors. nandbiterrs, nandpagetest and nandsubpagetest userspace tests from mtdutils run without errors and UBIFS can successfully be mounted.

2019-06-27mtd: rawnand: mtk: Improve data sampling timing for read cycleXiaolei Li
Currently, we expand RE# low level time by choosing the max value between RE# pulse width and RE# access time, and sample data at the rising edge of RE#. Then, if RE# access time is bigger than RE# pulse width, the real read cycle time may be more than NAND SPEC required. This makes read performance be worse than that expected. This patch improves data sampling timing by calculating RE# low level time according to RE# pulse width. If RE# access time is bigger than RE# pulse width, then delay sampling data timing.

2019-06-27mtd: rawnand: mtk: Correct low level time calculation of r/w cycleXiaolei Li
At present, the flow of calculating AC timing of read/write cycle in SDR mode is that: At first, calculate high hold time which is valid for both read and write cycle using the max value between tREH_min and tWH_min. Secondly, calculate WE# pulse width using tWP_min. Thridly, calculate RE# pulse width using the bigger one between tREA_max and tRP_min. But NAND SPEC shows that Controller should also meet write/read cycle time. That is write cycle time should be more than tWC_min and read cycle should be more than tRC_min. Obviously, we do not achieve that now. This patch corrects the low level time calculation to meet minimum read/write cycle time required. After getting the high hold time, WE# low level time will be promised to meet tWP_min and tWC_min requirement, and RE# low level time will be promised to meet tREA_max, tRP_min and tRC_min requirement.

2019-06-27mtd: rawnand: use longest matching patternStefan Agner
Sometimes the exec_op parser does not choose the optimal pattern if multiple patterns with optional elements are available. Since the stack automatically splits operations in multiple exec_op calls, a non-optimal pattern gets broken up into multiple calls. E.g. an OOB read using the vf610 driver: nand: executing subop: nand: ->CMD [0x00] nand: ->ADDR [5 cyc: 00 08 ea 94 02] nand: ->CMD [0x30] nand: ->WAITRDY [max 200000 ms] nand: DATA_IN [64 B] nand: executing subop: nand: CMD [0x00] nand: ADDR [5 cyc: 00 08 ea 94 02] nand: CMD [0x30] nand: WAITRDY [max 200000 ms] nand: ->DATA_IN [64 B] However, the vf610 driver has a pattern which can execute the complete command in a single go... This patch makes sure that the longest matching pattern is chosen instead of the first (potentially only partial) match. With this change the vf610 reads the OOB in a single exec_op call: nand: executing subop: nand: ->CMD [0x00] nand: ->ADDR [5 cyc: 00 08 c0 1d 00] nand: ->CMD [0x30] nand: ->WAITRDY [max 200000 ms] nand: ->DATA_IN [64 B] Reported-by: Sascha Hauer <s.hauer@pengutronix.de> Suggested-by: Boris Brezillon <boris.brezillon@collabora.com> Tested-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull SPDX fixes from Greg KH: "Here are just two small patches, that fix up some found SPDX identifier issues. The first patch fixes an error in a previous SPDX fixup patch, that causes build errors when doing 'make clean' on the tree (the fact that almost no one noticed it reflects the fact that kernel developers don't like doing that option very often...) The second patch fixes up a number of places in the tree where people mistyped the string "SPDX-License-Identifier". Given that people can not even type their own name all the time without mistakes, this was bound to happen, and odds are, we will have to add some type of check for this to checkpatch.pl to catch this happening in the future. Both of these have passed testing by 0-day" * tag 'spdx-5.2-rc3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: treewide: fix typos of SPDX-License-Identifier crypto: ux500 - fix license comment syntax error

A fix for a bug where a user requesting an unsupported branch sampling filter can corrupt PMU state, preventing the PMU from counting properly. And finally a fix for a bug in our support for kexec_file_load(), which prevented loading a kernel and initramfs. Most versions of kexec don't yet use kexec_file_load().
