MTD: nand: mxs_nand: Allow driver to auto setup ECC in SPL

2019-02-15T11:42:13Z

The initialization of the NAND in SPL hard-coded ecc.bytes, ecc.size, and ecc.strength which may work for some NAND parts, but it not appropriate for others. With the pending patch "mxs_nand: Fix BCH read timeout error on boards requiring ECC" the driver can auto configure the ECC when these entries are blank. This patch has been tested in NAND flash with oob 64 and oob 128. Signed-off-by: Adam Ford Tested-by: Jörg Krause Acked-by: Tim Harvey Tested-by: Tim Harvey

MTD: NAND: mxs_nand_init_dma: Make mxs_nand_init_dma static

2019-02-15T11:36:44Z

mxs_nand_init_dma is only referenced from mxs_nand.c. It's not referenced in any headers or outside code, so this patch defines it as static. Signed-off-by: Adam Ford

MTD: mxs_nand: Fix BCH read timeout error on boards requiring ECC

2019-02-15T11:36:08Z

The LogicPD board uses a Micron Flash with ECC. To boot this from SPL, the ECC needs to be correctly configured or the BCH engine times out. Signed-off-by: Adam Ford Acked-by: Stefan Agner Tested-by: Jörg Krause Acked-by: Tim Harvey Tested-by: Tim Harvey

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.

mtd: spi: sf_probe: Add "jedec, spi-nor" compatible string

2019-02-07T10:03:21Z

Linux uses "jedec,spi-nor" as compatible string for JEDEC compatible SPI Flash device nodes. Therefore make U-Boot also to look for the same compatible string so that we can use Linux DTS files as is.
