2019-06-06mtd: Fix get_mtdparts()Patrice Chotard
When ENV_IS_IN_UBI is enable, get_mtdparts is called before relocation. During first get_mtdparts() call, mtdparts is not available in environment, it can be retrieved by calling board_mtdparts_default(), but following env_set() do nothing as we are before relocation. Finally mtdparts is still not available in environment. At second get_mtdparts() call, use_defaults is false, but mtdparts is still not in environment and is NULL. Remove use_defaults bool, only mtdparts criteria is useful.

2019-05-03mtd: spi-nor: fix page program issue when using spi-mem driverWeijie Gao
Some SPI controllers can't write nor->page_size bytes in a single step because their TX FIFO is too small, but when that happens we should make sure a WRITE_EN command before each write access and READ_SR command after each write access is issued. We should allow nor->write() to return a size that is smaller than the requested write size to gracefully handle this case. Also, the spi_nor_write_data() should return the actual number of bytes that were written during the spi_mem_exec_op() operation. This patch is a combination of two commits backported from kernel: commit 630d6bd8a3b4 ("mtd: spi-nor: Support controllers with limit ...") commit 3baa8ec88c2f ("mtd: devices: m25p80: Make sure WRITE_EN is ...")

2019-04-12dm: spi: Read default speed and mode values from DTPatrick Delaunay
This patch update the behavior introduced by commit 96907c0fe50a ("dm: spi: Read default speed and mode values from DT") In case of DT boot, don't read default speed and mode for SPI from CONFIG_* but instead read from DT node. This will make sure that boards with multiple SPI/QSPI controllers can be probed at different bus frequencies and SPI modes. Remove also use in boards of the value speed=0 (no more supported) for ENV in SPI by using CONFIG_ENV_SPI_MAX_HZ=0. DT values will be always used when available (full DM support of SPI slave with available DT node) even if speed and mode are requested; for example in splash screen support (in splash_sf_read_raw) or in SPL boot (in spl_spi_load_image). The caller of spi_get_bus_and_cs() no more need to force speed=0. But the current behavior don't change if the SPI slave is not present (device with generic driver is created automatically) or if platdata is used (CONFIG_OF_PLATDATA).

Replace the ad-hoc erase operation implementation with a simple spi_mem_op implementation of the same functionality. This is a minor optimization and removal of the ad-hoc code. This however also changes the behavior of the execution of the erase opcode from two separate transfer requests to the SPI NOR driver to one transfer request to the SPI NOR driver. The former was how U-Boot behaved before the SPI NOR framework was imported and the later was introduced by the SPI NOR framework. The former is more optimal, so keep that.

2019-04-12mtd: fix Coverity integer handling issueMiquel Raynal
A Coverity robot reported an integer handling issue (OVERFLOW_BEFORE_WIDEN) in the potentially overflowing expression: (mtd_div_by_ws(mtd->size, mtd) - mtd_div_by_ws(offs, mtd)) * mtd_oobavail(mtd, ops) While such overflow will certainly never happen due to the numbers handled, it is cleaner to fix this operation anyway. The problem is that all the maths include 32-bit quantities, while the result is stored in an explicit 64-bit value. As maxooblen will just be compared with a size_t, let's change the type of the variable to a size_t. This will not fix anything but will clarify a bit the situation. Then, do an explicit cast to fix Coverity warning. Addresses-Coverity-ID: 184180 ("Integer handling issues") Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

2019-03-13MTD: mxs_nand_spl: Redo the way nand_init initializesAdam Ford
Currently the spl system calls nand_init which does nothing. It isn't until an attempt to load from NAND that it gets initialized. Subsequent attempts to load just skip the initialization because NAND is already initialized. This moves the contents of mxs_nand_init to nand_init. In the event of an error, it clears the number of nand chips found. Any attempts to use nand will check if there are nand chips available instead of actually doing the initialization at that time. If there are none, it will return an error to the higher level calls. Signed-off-by: Adam Ford <aford173@gmail.com>
