mtd: cqspi: Fix division by zero

2021-10-04T12:51:14Z

Both dummy.nbytes and dummy.buswidth may be zero. By not checking the later, it is possible to trigger division by zero and a crash. This does happen with tiny SPI NOR framework in SPL. Fix this by adding the check and returning zero dummy bytes in such a case.

pci: Drop DM_PCI

This option has not effect now. Drop it, using PCI instead where needed. Signed-off-by: Simon Glass

spi: zynqmp_gqspi: Fix dma alignment issue

2021-09-03T07:15:01Z

DMA is aligned to ARCH_DMA_MINALIGN(64 bytes), but as per spec, alignment required is 4bytes only. Change DMA alignment from ARCH_DMA_MINALIGN to GQSPI_DMA_ALIGN. Remove alignment of data length in non-exponential case. Some minor improvements in the initialization to initialize gen_fifo threshold and disable qspi controller while setting config register.

spi: zynqmp_gqspi: Switch genfifo start to manual mode

2021-09-03T07:14:58Z

Current implementation uses auto mode for starting generic FIFO. The recommendation from IP designers is to use manual mode, hence change to manual start mode. In fill genfifo first write to genfio and then trigger manual start. Also enable and check for genfifo empty interrupt status in place of genfifo not full interrupt.

spi: nxp_fspi: Ensure width is respected in spi-mem operations

2021-08-18T10:25:15Z

Import linux commit 007773e16a6f ("spi: nxp-fspi: Ensure width is respected in spi-mem operations") to fix SPI access on boards which don't have all SPI I/O lines connected to the flash. Since commit 71025f013ccb ("mtd: spi-nor-core: Rework hwcaps selection") u-boot figures out the capabilities by looking at spi_mem_supports_op(). The FlexSPI driver doesn't take the board layout into account. Fix that.

spi: rockchip_sfc: add support for Rockchip SFC

2021-08-12T01:34:11Z

This patch adds support for the Rockchip serial flash controller found on the PX30 SoC. It should work for versions 3-5 of the SFC IP, however I am only able to test it on v3. This is adapted from the WIP SPI-MEM driver for the SFC on mainline Linux. Note that the main difference between this and earlier versions of the driver is that this one does not support DMA. In testing the performance difference (performing a dual mode read on a 128Mb chip) is negligible. DMA, if used, must also be disabled in SPL mode when using A-TF anyway.

spi: spi-mem-nodm: Fix read data size issue

2021-08-03T06:20:37Z

When slave drivers don't set the max_read_size, the spi-mem should directly use data.nbytes and not limit to any size. But current logic will limit to the max_write_size. This commit mirrors the same changes in the dm version done in commit 535b1fdb8e5e ("spi: spi-mem: Fix read data size issue"). Signed-off-by: Bin Meng Reviewed-by: Jagan Teki

spi: ich: Limit slave->max_read_size

2021-08-02T07:11:40Z

Since commit 43c145b8b3ee ("spi: ich: Correct max-size bug in ich_spi_adjust_size()") (in v2020.04-rc1), SPI flash read no longer works with ICH SPI controller in software sequencer mode. ICH controller can only transfer a small number of bytes at once. Before commit 43c145b8b3ee, the logic happens to make sure data.nbytes is limited to slave->max_write_size but after commit 43c145b8b3ee data.nbytes is no longer limited because slave->max_read_size is not initialized with a valid number.
