Fix corner case in bad block table handling.

2020-08-05T03:30:02Z

In the unlikely event that both blocks 10 and 11 are marked as bad (on a 32 bit machine), then the process of marking block 10 as bad stomps on cached entry for block 11. There are (of course) other examples. Signed-off-by: Patrick Doyle Reviewed-by: Richard Weinberger

nand: Drop dm.h header file

2020-08-04T02:19:54Z

This header file should not be included in other header files. Remove it and use a forward declaration instead. Signed-off-by: Simon Glass

mtd: spi-nor: Tidy up error handling / debug code

2020-08-04T02:19:54Z

The -ENODEV error value in spi_nor_read_id() is incorrect since there clearly is a device - it just cannot be supported. Use -ENOMEDIUM instead which has the virtue of being less common. Fix the return value in spi_nor_scan(). Also there are a few printf() statements which should be debug() since they bloat the code with unused strings at present. Fix those while here.

spi: Allow separate control of SPI_FLASH_TINY for SPL/TPL

2020-08-04T02:19:54Z

In some cases SPL needs to be able to erase but TPL just needs to read. Allow these to have separate settings for SPI_FLASH_TINY. Signed-off-by: Simon Glass

mtd: spinand: micron: identify SPI NAND device with Continuous Read mode

2020-07-20T16:58:33Z

Add SPINAND_HAS_CR_FEAT_BIT flag to identify the SPI NAND device with the Continuous Read mode. Some of the Micron SPI NAND devices have the "Continuous Read" feature enabled by default, which does not fit the subsystem needs. In this mode, the READ CACHE command doesn't require the starting column address. The device always output the data starting from the first column of the cache register, and once the end of the cache register reached, the data output continues through the next page. With the continuous read mode, it is possible to read out the entire block using a single READ command, and once the end of the block reached, the output pins become High-Z state. However, during this mode the read command doesn't output the OOB area. Hence, we disable the feature at probe time. Signed-off-by: Shivamurthy Shastri Acked-by: Jagan Teki
