2023-11-07spi: Add <errno.h> to spi-mem-nodm.cTom Rini
This file uses errno return values in functions, so include <errno.h> here rather than rely on indirect inclusion. Signed-off-by: Tom Rini <trini@konsulko.com>
2021-08-03spi: spi-mem-nodm: Fix read data size issueBin Meng
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").

2021-06-28mtd: spi-nor-core: Rework hwcaps selectionPratyush Yadav
The spi-mem layer provides a spi_mem_supports_op() function to check whether a specific operation is supported by the controller or not. This is much more accurate than the hwcaps selection logic based on SPI_{RX,TX}_ flags. Rework the hwcaps selection logic to use spi_mem_supports_op(). To make sure the build doesn't break for boards not using CONFIG_DM_SPI, add a simple SPI_{RX,TX}_ based hwcaps selection logic in spi-mem-nodm similar to spi_mem_default_supports_op(). This change is only compile-tested. To avoid SPL size problems on the x530 board, the old hwcaps selection is still kept around. Leaving the code in-place was getting difficult to read and understand, so the code is restructured to have it all in one isolated function. As a result of this, the parameter hwcaps to spi_nor_setup() is no longer needed. Remove it. Based on the Linux commit c76f5089796a (mtd: spi-nor: Rework hwcaps selection for the spi-mem case, 2019-08-06) Signed-off-by: Pratyush Yadav <p.yadav@ti.com> Reviewed-by: Jagan Teki <jagan@amarulasolutions.com>
2021-06-28spi: spi-mem: allow specifying a command's extensionPratyush Yadav
In xSPI mode, flashes expect 2-byte opcodes. The second byte is called the "command extension". There can be 3 types of extensions in xSPI: repeat, invert, and hex. When the extension type is "repeat", the same opcode is sent twice. When it is "invert", the second byte is the inverse of the opcode. When it is "hex" an additional opcode byte based is sent with the command whose value can be anything. So, make opcode a 16-bit value and add a 'nbytes', similar to how multiple address widths are handled. All usages of sizeof(op->cmd.opcode) also need to be changed to be op->cmd.nbytes because that is the actual indicator of opcode size.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.
