2018-06-27mtd: nand: mxs_nand_spl: add mxs_flash_full_identJörg Krause
For now, the existing SPL MXS NAND driver only supports to identify ONFi-compliant NAND chips. In order to allow identifying non-ONFi-compliant chips add `mxs_flash_full_ident()` which uses the `nand_get_flash_type()` functionality from `nand_base.c` to lookup for supported NAND chips in the chip ID list. For compatibility reason the full identification support is only available if the config option `CONFIG_SPL_NAND_IDENT` is enabled. The lookup was tested on a custom i.MX6ULL board with a Toshiba TC58NVG1S3HTAI0 NAND chip. Signed-off-by: Jörg Krause <joerg.krause@embedded.rocks>
2018-06-27mtd: nand: mxs_nand_spl: refactor mxs_flash_identJörg Krause
The existing `mxs_flash_ident()` is limited to identify ONFi compliant NAND chips only. In order to support non-ONFi NAND chips refactor the function and rename it to `mxs_flash_onfi_ident()`. A follow-up patch will add `mxs_flash_full_ident()` which allows to use the chip ID list to lookup for supported NAND flashs. Signed-off-by: Jörg Krause <joerg.krause@embedded.rocks>
2018-06-27spl, nand: add option CONFIG_SPL_NAND_IDENT to lookup for supported NAND chipsJörg Krause
Add the config option `CONFIG_SPL_NAND_IDENT` for using the NAND chip ID list to identify the NAND flash in SPL. Signed-off-by: Jörg Krause <joerg.krause@embedded.rocks>
2018-06-27mtd: nand: export nand_get_flash_type functionJörg Krause
`nand_get_flash_type()` allows identification of supported NAND flashs. The function is useful in SPL (like mxs_nand_spl.c) to lookup for a NAND flash (which does not support ONFi) instead of using nand_simple.c and hard-coding all required NAND parameters.

Since commit 1da1938d57b3 ("spl: Add default values for ARCH_MX7") CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_USE_SECTOR is selected by default on i.MX7 platforms, so remove it from the board defconfig. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com>
2018-06-27imx6ul: geam: Fix fdt_file mismatchJagan Teki
fdt_file is looking for imx6ul-geam-kit.dtb but Linux has imx6ul-geam.dtb, since Linux skipped -kit on file name by below commit. "ARM: dts: imx6ul-geam: Skip suffix -kit from dts name" (sha1: 182de5ebce71e469cfa686fcdf08c9cbe11ece97) So, due to this mismatch U-Boot failed to pick the proper dtb which eventually break the Linux boot. This patch fixed this mismatch by - renaming dts files - update config option to use new dtb file - update fdt_file to new dtb file name Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com>
2018-06-27power: pmic: Let PFUZE3000 see all 256 registersTrent Piepho
The PFUZE3000 uses registers addresses up to 0xff. The DM pfuze100 driver supports both pfuze100 and pfuze3000. Allow it to use the device type to return the correct number of registers. Also rename the too generic PMIC_NUM_OF_REGS enumeration value for pfuze3000 to match the other "PFUZE3000_" prefixed enumerations and the pfuze100 enumeration value PFUZE100_NUM_OF_REGS.

2018-06-27mtd: nand: mxs_nand: add support for specific ECC strengthStefan Agner
Add support for specified ECC strength/size using device tree properties nand-ecc-strength/nand-ecc-step-size. This aligns behavior with the mainline driver, such that: - If fsl,use-minimal-ecc is requested it will use data from data sheet/ONFI. If this is not available the driver will fail. - If nand-ecc-strength/nand-ecc-step-size are specified those value will be used. - By default maximum possible ECC strength is used Signed-off-by: Stefan Agner <stefan.agner@toradex.com>

2018-06-27mtd: nand: mxs_nand: report correct ECC parametersStefan Agner

2018-06-18mx6cuboxi: fix 4GB ddr memory detectionJon Nettleton
The soms with 4GB ddr have a rowaddr of 16 not 15, this allows the detection mechanism to properly identify them as 4GB. However these soms can be populated with whatever amount of memory the customer requests therefor we need a ram stride test. We can not use the get_ram_size() function because not all 4GB's of DDR is addressable on a 32-bit architecture. Therefore instead we use a memory stride of 128MB's and look for the address that the memory wraps. This function is used for all som types to catch most memory configurations. This is a revised version of Rabeeh Khoury's original code.
