2020-03-23mtd: spi-nor: controllers: aspeed-smc: Replace zero-length array with ↵Gustavo A. R. Silva1-1/+1
flexible-array member The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-03-23mtd: spi-nor: Clear WEL bit when erase or program errors occurTudor Ambarus1-0/+22
When an Erase or Program error occurs on a spansion/cypress or a micron flash, the WEL bit remains set to one and should be cleared with a WRDI command in order to protect against inadvertent writes that can possible corrupt the contents of the memory. Winbond, macronix, gd, etc., do not support the E_ERR and P_ERR bits in the Status Register and always clear the WEL bit regardless of the outcome of the erase or page program operation (ex w25q40bw, MX25L25635E). Issue a WRDI command when erase or page program errors occur. Reported-by: John Garry <[email protected]> Signed-off-by: Tudor Ambarus <[email protected]> Tested-by: John Garry <[email protected]>

Commit a0900d0195d2 ("mtd: spi-nor: Prepare core / manufacturer code split") moved all SPI NOR controller drivers to a controllers/ sub-directory. However, the moved nxp-spifi.c file was referenced in the ARM/LPC18XX ARCHITECTURE entry in MAINTAINERS.

The SPI NOR controllers drivers must not be able to use structures that are meant just for the SPI NOR core. struct spi_nor_flash_parameter is filled at run-time with info gathered from flash_info, manufacturer and sfdp data. struct spi_nor_flash_parameter should be opaque to the SPI NOR controller drivers, make sure it is. spi_nor_option_flags, spi_nor_read_command, spi_nor_pp_command, spi_nor_read_command_index and spi_nor_pp_command_index are defined for the core use, make sure they are opaque to the SPI NOR controller drivers.

Rename (*set_4byte)() to (*set_4byte_addr_mode)() for a better differentiation between the 4 byte address mode and opcodes. Rename macronix_set_4byte() to spi_nor_set_4byte_addr_mode(), it will be the only 4 byte address mode method exposed to the manufacturer drivers. Here's how the manufacturers enter and exit the 4 byte address mode: - eon, gidadevice, issi, macronix, xmc use EN4B/EX4B - micron-st needs WEN. st_micron_set_4byte_addr_mode() will become a private method, as they are the only ones that need WEN before the EN4B/EX4B commands. - newer spansion have a 4BAM opcode (this translates to a new, public command). Older spansion flashes use the BRWR command (legacy in core.c -> spansion_set_4byte_addr_mode()) - winbond's method is hackish and may be reason for just a flash fixup hook -> private method Signed-off-by: Tudor Ambarus <[email protected]> Reviewed-by: Vignesh Raghavendra <[email protected]>

spi: Rewrite mtk-quadspi spi-nor driver with spi-mem This patchset from Chuanhong Guo <[email protected]> adds a spi-mem driver for Mediatek SPI-NOR controller, which already has limited support by mtk-quadspi. This new driver can make use of full quadspi capability of this controller. The mtk-quadspi driver is replaced by the new spi-mtk-nor driver. Merge it in spi-nor/next to avoid conflicts during the release cycle.

spi-mtk-nor is a driver to replace mtk-quadspi and they have almost the same device-tree bindings. Reuse this binding documentation and convert it for new driver: 1. "Mediatek SoCs" -> "Mediatek ARM SoCs" because MTK MIPS SoCs use different controllers. 2. document "interrupts" as a required property because it's available on all SoCs with this controller and new driver takes advantages of it. It's implemented as optional only to maintain backward compatibility. 3. add a dummy interrupt binding in example.

2020-03-11spi: add support for mediatek spi-nor controllerChuanhong Guo3-0/+700
This is a driver for mtk spi-nor controller using spi-mem interface. The same controller already has limited support provided by mtk-quadspi driver under spi-nor framework and this new driver is a replacement for the old one. Comparing to the old driver, this driver has following advantages: 1. It can handle any full-duplex spi transfer up to 6 bytes, and this is implemented using generic spi interface. 2. It take account into command opcode properly. The reading routine in this controller can only use 0x03 or 0x0b as opcode on 1-1-1 transfers, but old driver doesn't implement this properly. This driver checks supported opcode explicitly and use (1) to perform unmatched operations. 3. It properly handles SFDP reading. Old driver can't read SFDP due to the bug mentioned in (2). 4. It can do 1-2-2 and 1-4-4 fast reading on spi-nor. These two ops requires parsing SFDP, which isn't possible in old driver. And the old driver is only flagged to support 1-1-2 mode. 5. It takes advantage of the DMA feature in this controller for long reads and supports IRQ on DMA requests to free cpu cycles from polling status registers on long DMA reading. It achieves up to 17.5MB/s reading speed (1-4-4 mode) which is way faster than the old one. IRQ is implemented as optional to maintain backward compatibility.

2020-03-11spi: make spi-max-frequency optionalChuanhong Guo1-7/+2
We only need a spi-max-frequency when we specifically request a spi frequency lower than the max speed of spi host. This property is already documented as optional property and current host drivers are implemented to operate at highest speed possible when spi->max_speed_hz is 0. This patch makes spi-max-frequency an optional property so that we could just omit it to use max controller speed.

spi_nor_spimem_xfer_data() being a helper function for the data reads/ writes contains 3 fragments that depend on the data direction; and I'm going to add another one to call the SPI dirmap API... I think this function should be split so that the common fragments are put into 2 functions, spi_nor_spimem_bounce() and spi_nor_spimem_exec_op() called from spi_nor_spimem_{read|write}_data(), and the data direction dependent bits moved back into those read/write functions -- that way we would be able to avoid *goto*s otherwise needed in the next patch adding the SPI dirmap support...
