2020-09-11mtd: nand: Fix nand write error with bad block addresses above 32-bitT Karthik Reddy
Nand writes should skip the bad blocks with "nand write" command. In case of bad blocks with above 32-bit address, nand_block_isbad() returns false due to truncated bad block address. In below code segment, if (nand_block_isbad(mtd, offset & ~(mtd->erasesize - 1))) offset is 64-bit and mtd->erasesize is 32-bit, hence the truncation is happening. Cast 'mtd->erasesize' with loff_t to fix this issue. Signed-off-by: T Karthik Reddy <t.karthik.reddy@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>

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.

The types of "offset" and "size" of "struct mtd_partition" are uint64_t, while mtd_parse_partitions() uses int to work with these values. When the offset reaches 2GB, it is interpreted as a negative value, which leads to error messages like mtd: partition "<partition name>" is out of reach -- disabled eg. when using the "ubi part" command.

2020-07-09core: add support for U_BOOT_DRIVER_ALIASWalter Lozano
Currently when using OF_PLATDATA the binding between devices and drivers is done trying to match the compatible string in the node with a driver name. However, usually a single driver supports multiple compatible strings which causes that only devices which its compatible string matches a driver name get bound. To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro, which generates no code at all, but allows an easy way to declare driver name aliases. Thanks to this, dtoc could be improve to look for the driver name based on its alias when it populates the U_BOOT_DEVICE entry.

2020-06-29spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*Lukasz Majewski
This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

2020-06-01sf: Drop spl_flash_get_sw_write_protJagan Teki
The get_sw_write_prot API is used to get the write-protected bits of flash by reading the status register and other wards it's API for reading register bits. 1) This kind of requirement can be achieved using existing flash operations and flash locking API calls instead of making a separate flash API. 2) Technically there is no real hardware user for this API to use in the source tree. 3) Having a flash operations API for simple register read bits also make difficult to extend the flash operations. 4) Instead of touching generic code, it is possible to have this functionality inside spinor operations in the form of flash hooks or fixups for associated flash chips. Considering all these points, this patch drops the get_sw_write_prot and associated code bases.

[ Linux commit 9afbe7c0140f663586edb6e823b616bd7076c00a ] If the write protect signal from this IP is connected to the NAND device, this IP can handle the WP# pin via the WRITE_PROTECT register. The Denali NAND Flash Memory Controller User's Guide describes this register like follows: When the controller is in reset, the WP# pin is always asserted to the device. Once the reset is removed, the WP# is de-asserted. The software will then have to come and program this bit to assert/de-assert the same. 1 - Write protect de-assert 0 - Write protect assert The default value is 1, so the write protect is de-asserted after the reset is removed. The driver can write to the device unless someone has explicitly cleared register before booting the kernel. The boot ROM of some UniPhier SoCs (LD4, Pro4, sLD8, Pro5) is the case; the boot ROM clears the WRITE_PROTECT register when the system is booting from the NAND device, so the NAND device becomes read-only. Set it to 1 in the driver in order to allow the write access to the device. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
