common: Move ARM cache operations out of common.h

2019-12-02T23:24:58Z

These functions are CPU-related and do not use driver model. Move them to cpu_func.h Signed-off-by: Simon Glass Reviewed-by: Daniel Schwierzeck Reviewed-by: Tom Rini

common: Move get_ticks() function out of common.h

spi: Add support for memory-mapped flash

2019-11-02T23:20:26Z

On x86 platforms the SPI flash can be mapped into memory so that the contents can be read with normal memory accesses. Add a new SPI method to find the location of the SPI flash in memory. This differs from the existing device-tree "memory-map" mechanism in that the location can be discovered at run-time. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

spi: mt7621-spi: restore default register value after each xfer

2019-10-25T15:20:44Z

Currently this driver uses a different way to implement the spi xfer, by modifying some fields of two registers, which is incompatible with the MTK's original SDK linux driver. This will cause the flash data being damaged by the SDK driver. This patch lets the mt7621_spi_set_cs() restore the original register fields after cs deactivated.

spi: mt7621-spi: remove data cache and rewrite its xfer function

2019-10-25T15:20:44Z

The mt7621 spi controller supports continuous generic half-duplex spi transaction. There is no need to cache xfer data at all. To achieve this goal, the OPADDR register must be used as the first data to be sent. And follows the eight generic DIDO registers. But one thing different between OPADDR and DIDO registers is OPADDR has a reversed byte order. With this patch, any amount of data can be read/written in a single xfer function call.

spi: mt7621-spi: use clock frequency from clk driver

2019-10-25T15:20:44Z

This patch lets the spi driver to use clock provided by the clk driver since the new clk-mt7628 driver provides accurate sys clock frequency. Signed-off-by: Weijie Gao
