2020-10-08cfi_flash: Fix devicetree address determinationAndre Przywara1-18/+6
The cfi-flash driver uses an open-coded version of the generic algorithm to decode and translate multiple frames of a "reg" property. This starts off the wrong foot by using the address-cells and size-cells properties of *this* very node, and not of the parent. This somewhat happened to work back when we were using a wrong default size of 2, but broke about a year ago with commit 0ba41ce1b781 ("libfdt: return correct value if #size-cells property is not present"). Instead of fixing the reinvented wheel, just use the generic function that does all of this properly. This fixes U-Boot on QEMU (-arm64), which was crashing due to decoding a wrong flash base address: DRAM: 1 GiB Flash: "Synchronous Abort" handler, esr 0x96000044 elr: 00000000000211dc lr : 00000000000211b0 (reloc) elr: 000000007ff5e1dc lr : 000000007ff5e1b0 x0 : 00000000000000f0 x1 : 000000007ff5e1d8 x2 : 000000007edfbc48 x3 : 0000000000000000 x4 : 0000000000000000 x5 : 00000000000000f0 x6 : 000000007edfbc2c x7 : 0000000000000000 x8 : 000000007ffd8d70 x9 : 000000000000000c x10: 0400000000000003 x11: 0000000000000055 ^^^^^^^^^^^^^^^^ Signed-off-by: Andre Przywara <andre.przywara@arm.com> Reviewed-by: Stefan Roese <sr@denx.de>

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.

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.

2020-06-29spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*Lukasz Majewski2-3/+3
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.

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.
