2019-11-03nand: mxs_nand: add API for switching different BCH layoutsIgor Opaniuk
On i.MX7 in a sake of reducing the disturbances caused by a neighboring cells in the FCB page in the NAND chip, a randomizer is enabled when reading the FCB page by ROM bootloader. Add API for setting BCH to specific layout (and restoring it back) used by ROM bootloader to be able to burn it in a proper way to NAND using nandbcb command.

2019-10-25drivers: nand: brcmnand: fix nand_chip ecc layout structureWilliam Zhang
The current brcmnand driver is based on 4.18 linux kernel which uses mtd_set_ooblayout to set ecc layout. But nand base code in u-boot is from old kernel which does not use this new API and expect nand_chip.ecc.layout structure to be set. This cause nand_scan_tail function running into a bug check if the device has a different oob size than the default ones. This patch ports the brcmstb_choose_ecc_layout function from kernel 4.6.7 that supports the ecc layout struture and replaces the mtd_set_ooblayout method Signed-off-by: William Zhang <william.zhang@broadcom.com> Reviewed-by: Philippe Reynes <philippe.reynes@softathome.com>

2019-10-25mtd: spi: Clean up usage of CONFIG_SPI_FLASH_MTDFrieder Schrempf
Most boards currently use SPI_FLASH_MTD only in U-Boot proper, not in SPL. They often rely on hacks in the board header files to include this option conditionally. To be able to fix this, we previously introduced a separate option SPL_SPI_FLASH_MTD. Therefore we can now adjust the Makefile and change the code in sf_probe.c and sf_internal.h to use CONFIG_IS_ENABLED(SPI_FLASH_MTD). We also need to move all occurences of CONFIG_SPI_FLASH_MTD from the header files to the according defconfigs. The affected boards are socfpga, aristainetos, cm_fx6, display5, ventana, rcar-gen2, dh_imx6 and da850evm. We do this all in one patch to guarantee bisectibility. This change was tested with buildman to make sure it does not introduce any regressions by comparing the resulting binary sizes.

Some users of static UBI volumes implement their own integrity check, thus making the volume CRC check done at open time useless. For instance, this is the case when one use the ubiblock + dm-verity + squashfs combination, where dm-verity already checks integrity of the block device but this time at the block granularity instead of verifying the whole volume.

2019-07-19i.MX6: nand: add nandbcb command for imxShyam Saini
Writing/updating boot image in nand device is not straight forward in i.MX6 platform and it requires boot control block(BCB) to be configured. It becomes difficult to use uboot 'nand' command to write BCB since it requires platform specific attributes need to be taken care of. It is even difficult to use existing msx-nand.c driver by incorporating BCB attributes like mxs_dma_desc does because it requires change in mtd and nand command. So, cmd_nandbcb implemented in arch/arm/mach-imx BCB contains two data structures, Firmware Configuration Block(FCB) and Discovered Bad Block Table(DBBT). FCB has nand timings, DBBT search area, page address of firmware. On summary, nandbcb update will - erase the entire partition - create BCB by creating 2 FCB/DBBT block followed by 1 FW block based on partition size and erasesize. - fill FCB/DBBT structures - write FW/SPL on FW1 - write FCB/DBBT in first 2 blocks for nand boot, up on reset bootrom look for FCB structure in first block's if FCB found the nand timings are loaded for further reads. once FCB read done, DTTB will load and finally firmware will be loaded which is boot image.

2019-07-09ubispl: add support for loading volumes by nameHamish Guthrie
The motivation is to use the UBI atomic volume rename functionality to allow double copy software updates on UBI. To that end the SPL is configured to always load the same volume name (e.g. "u-boot"), whereas a software updater always installs into the secondary volume "u-boot_r". After successful installation, these two volume names are switched. This extension is protected by #ifdefs as it will somewhat slow down loading of volumes by id. This is because the code needs to disable the optimization of ignoring all volume ids which are not to-be-loaded, since these can only be resolved after attaching. This adds two vtbl related functions from Linux, which are taken from the same kernel version as the current main U-Boot UBI code (Linux 4.2 64291f7db5bd8).

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.
