2018-09-19mtd: nand: pxa3xx: Fix READOOB implementationBoris Brezillon
In the current driver, OOB bytes are accessed in raw mode, and when a page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the driver must read the whole spare area (64 bytes in case of a 2k page, 16 bytes for a 512 page). The driver was only reading the free OOB bytes, which was leaving some unread data in the FIFO and was somehow leading to a timeout. We could patch the driver to read ->spare_size + ->ecc_size instead of just ->spare_size when READOOB is requested, but we'd better make in-band and OOB accesses consistent. Since the driver is always accessing in-band data in non-raw mode (with the ECC engine enabled), we should also access OOB data in this mode. That's particularly useful when using the BCH engine because in this mode the free OOB bytes are also ECC protected.

2018-09-19mtd: nand: pxa3xx_nand: add support for partial chunksOfer Heifetz
This commit is needed to properly support the 8-bits ECC configuration with 4KB pages. When pages larger than 2 KB are used on platforms using the PXA3xx NAND controller, the reading/programming operations need to be split in chunks of 2 KBs or less because the controller FIFO is limited to about 2 KB (i.e a bit more than 2 KB to accommodate OOB data). Due to this requirement, the data layout on NAND is a bit strange, with ECC interleaved with data, at the end of each chunk. When a 4-bits ECC configuration is used with 4 KB pages, the physical data layout on the NAND looks like this: | 2048 data | 32 spare | 30 ECC | 2048 data | 32 spare | 30 ECC | So the data chunks have an equal size, 2080 bytes for each chunk, which the driver supports properly. When a 8-bits ECC configuration is used with 4KB pages, the physical data layout on the NAND looks like this: | 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 64 spare | 30 ECC | So, the spare area is stored in its own chunk, which has a different size than the other chunks. Since OOB is not used by UBIFS, the initial implementation of the driver has chosen to not support reading this additional "spare" chunk of data. Unfortunately, Marvell has chosen to store the BBT signature in the OOB area. Therefore, if the driver doesn't read this spare area, Linux has no way of finding the BBT. It thinks there is no BBT, and rewrites one, which U-Boot does not recognize, causing compatibility problems between the bootloader and the kernel in terms of NAND usage. To fix this, this commit implements the support for reading a partial last chunk. This support is currently only useful for the case of 8 bits ECC with 4 KB pages, but it will be useful in the future to enable other configurations such as 12 bits and 16 bits ECC with 4 KB pages, or 8 bits ECC with 8 KB pages, etc. All those configurations have a "last" chunk that doesn't have the same size as the other chunks. In order to implement reading of the last chunk, this commit: - Adds a number of new fields to the pxa3xx_nand_info to describe how many full chunks and how many chunks we have, the size of full chunks and partial chunks, both in terms of data area and spare area. - Fills in the step_chunk_size and step_spare_size variables to describe how much data and spare should be read/written for the current read/program step. - Reworks the state machine to accommodate doing the additional read or program step when a last partial chunk is used.

2018-09-19mtd: pxa3xx_nand: Fix initial controller configurationOfer Heifetz
The Data Flash Control Register (NDCR) contains two types of parameters: those that are needed for device identification, and those that can only be set after device identification. Therefore, the driver can't set them all at once and instead needs to configure the first group before nand_scan_ident() and the second group later. Let's split pxa3xx_nand_config in two halves, and set the parameters that depend on the device geometry once this is known.

2018-09-19mtd: pxa3xx_nand: Increase the initial chunk sizeOfer Heifetz
The chunk size represents the size of the data chunks, which is used by the controllers that allow to split transferred data. However, the initial chunk size is used in a non-split way, during device identification. Therefore, it must be large enough for all the NAND commands issued during device identification. This includes NAND_CMD_PARAM which was recently changed to transfer up to 2048 bytes (for the redundant parameter pages). Thus, the initial chunk size should be 2048 as well. On Armada 370/XP platforms (NFCv2) booted without the keep-config devicetree property, this commit fixes a timeout on the NAND_CMD_PARAM command: [..] pxa3xx-nand f10d0000.nand: This platform can't do DMA on this device pxa3xx-nand f10d0000.nand: Wait time out!!! nand: device found, Manufacturer ID: 0x2c, Chip ID: 0x38 nand: Micron MT29F8G08ABABAWP nand: 1024 MiB, SLC, erase size: 512 KiB, page size: 4096, OOB size: 224 This commit is taken from Linux: 'commit c7f00c29aa8' ("mtd: pxa3xx_nand: Increase the initial chunk size") Signed-off-by: Chris Packham <judge.packham@gmail.com> Signed-off-by: Ofer Heifetz <oferh@marvell.com> Reviewed-by: Igal Liberman <igall@marvell.com> Cc: Stefan Roese <sr@denx.de> Cc: Simon Glass <sjg@chromium.org> Signed-off-by: Stefan Roese <sr@denx.de>

2018-09-19mtd: nand: pxa3xx_nand: Increase initial buffer sizeOfer Heifetz
The initial buffer is used for the initial commands used to detect a flash device (STATUS, READID and PARAM). ONFI param page is 256 bytes, and there are three redundant copies to be read. JEDEC param page is 512 bytes, and there are also three redundant copies to be read. Hence this buffer should be at least 512 x 3. This commits rounds the buffer size to 2048.

2018-09-19phy: marvell: Support changing SERDES map in board fileMarek Behún
This adds a weak definition of comphy_update_map to comphy_core, which does nothing. If this function is defined elsewhere, for example in board file, the board file can change some parameters of SERDES configuration. This is needed on Turris Mox, where the SERDES speed on lane 1 has to be set differently when SFP module is connected and when Topaz Switch module is connected. This is a temporary solution. When the comphy driver for armada-3720 will be added to the kernel, the comphy driver in u-boot shall also be updated and this should be done differently then.
