mtd: spi-nor: fix page program issue when using spi-mem driver

2019-05-03T09:56:12Z

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 ...")

dm: spi: Read default speed and mode values from DT

2019-04-12T06:24:50Z

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).

mtd: spi: Replace ad-hoc default implementation with spi_mem_op

2019-04-12T06:12:48Z

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.

mtd: spi: Add lightweight SPI flash stack for SPL

2019-02-07T10:03:21Z

Add a tiny SPI flash stack that just supports reading data/images from SPI flash. This is useful for boards that have SPL size constraints and would need to use SPI flash framework just to read images/data from flash. There is approximately 1.5 to 2KB savings with this.
