2020-05-28mtd: spinand: toshiba: Rename function name to change suffix and prefix (8Gbit)Yoshio Furuyama
The suffix was changed from "G" to "J" to classify between 1st generation and 2nd generation serial NAND devices (which now belong to the Kioxia brand). As reference that's 1st generation device of 1Gbit product is "TC58CVG0S3HRAIG" 2nd generation device of 1Gbit product is "TC58CVG0S3HRAIJ". The 8Gbit type "TH58CxG3S0HRAIJ" is new to Kioxia's serial NAND lineup and the prefix was changed from "TC58" to "TH58". Thus the functions were renamed from tc58cxgxsx_*() to tx58cxgxsxraix_*().

2020-05-22mtd: rawnand: denali: deassert write protect pinMasahiro Yamada
[ Linux commit 9afbe7c0140f663586edb6e823b616bd7076c00a ] If the write protect signal from this IP is connected to the NAND device, this IP can handle the WP# pin via the WRITE_PROTECT register. The Denali NAND Flash Memory Controller User's Guide describes this register like follows: When the controller is in reset, the WP# pin is always asserted to the device. Once the reset is removed, the WP# is de-asserted. The software will then have to come and program this bit to assert/de-assert the same. 1 - Write protect de-assert 0 - Write protect assert The default value is 1, so the write protect is de-asserted after the reset is removed. The driver can write to the device unless someone has explicitly cleared register before booting the kernel. The boot ROM of some UniPhier SoCs (LD4, Pro4, sLD8, Pro5) is the case; the boot ROM clears the WRITE_PROTECT register when the system is booting from the NAND device, so the NAND device becomes read-only. Set it to 1 in the driver in order to allow the write access to the device. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

[2] if the (N <= threshold) is true, we continue to read out the page with ECC disabled. and we count the bitflips again, assume it is N2. (We read out the whole page, not just a chunk, this makes the check more strictly, and make the code more simple.) [3] if the (N2 <= threshold) is true again, we can regard this is a erased page. This is because a real erased page is full of 0xFF(maybe also has several bitflips), while a page contains the 0xFF data will definitely has many bitflips in the ECC parity areas.

2020-05-10mtd: gpmi: change the BCH layout setting for large oob NANDYe Li
The code change updated the NAND driver BCH ECC layout algorithm to support large oob size NAND chips(oob > 1024 bytes) and proposed a new way to set ECC layout. Current implementation requires each chunk size larger than oob size so the bad block marker (BBM) can be guaranteed located in data chunk. The ECC layout always using the unbalanced layout(Ecc for both meta and Data0 chunk), but for the NAND chips with oob larger than 1k, the driver cannot support because BCH doesn’t support GF 15 for 2K chunk. The change keeps the data chunk no larger than 1k and adjust the ECC strength or ECC layout to locate the BBM in data chunk. General idea for large oob NAND chips is 1.Try all ECC strength from the minimum value required by NAND spec to the maximum one that works, any ECC makes the BBM locate in data chunk can be chosen. 2.If none of them works, using separate ECC for meta, which will add one extra ecc with the same ECC strength as other data chunks. This extra ECC can guarantee BBM located in data chunk, of course, we need to check if oob can afford it. Previous code has two methods for ECC layout setting, the legacy_calc_ecc_layout and calc_ecc_layout_by_info, the difference between these two methods is, legacy_calc_ecc_layout set the chunk size larger chan oob size and then set the maximum ECC strength that oob can afford. While the calc_ecc_layout_by_info set chunk size and ECC strength according to NAND spec. It has been proved that the first method cannot provide safe ECC strength for some modern NAND chips, so in current code, 1. Driver read NAND parameters first and then chose the proper ECC layout setting method. 2. If the oob is large or NAND required data chunk larger than oob size, chose calc_ecc_for_large_oob, otherwise use calc_ecc_layout_by_info 3. legacy_calc_ecc_layout only used for some NAND chips does not contains necessary information. So this is only a backup plan, it is NOT recommended to use these NAND chips.

This is caused by comparing NAND_CMD_NONE (int) with end_cmd (u8). end_cmd will be promoted by the int value -1 and therefore is not equal to 0xFF.

2020-02-01mtd: rawnand: denali-spl: Add missing hardware init on SoCFPGAMarek Vasut
On Altera SoCFPGA, upon either cold-boot or power-on reset, the Denali NAND IP is initialized by the BootROM ; upon warm-reset, the Denali NAND IP is NOT initialized by BootROM. In fact, upon warm-reset, the SoCFPGA BootROM checks whether the SPL image in on-chip RAM is valid and if so, completely skips re-loading the SPL from the boot media. This does sometimes lead to problems where the software left the boot media in inconsistent state before warm-reset, and because the BootROM does not reset the boot media, the boot media is left in this inconsistent state, often until another component attempts to access the boot media and fails with an difficult to debug failure. To mitigate this problem, the SPL on Altera SoCFPGA always resets all the IPs on the SoC early on boot. This results in a couple of register values, pre-programmed by the BootROM, to be lost during this reset. To restore correct operation of the IP on SoCFPGA, these values must be programmed back into the controller by the driver. Note that on other SoCs which do not use the HW-controlled bootstrap, more registers may have to be programmed. This also aligns the SPL behavior with the full Denali NAND driver, which sets these values in denali_hw_init().
