From 364174b2d3bcad1a3ebd30c0eec9307ae5cb477a Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Mon, 26 Jul 2021 21:35:28 +0200 Subject: [PATCH] spi: nxp_fspi: Ensure width is respected in spi-mem operations 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.
