This series allows to use it from U-Boot and boot from it. This series applies to u-boot/master. Changes since v2: - rebased on master - droped 5th path, and enabled CONFIG_SPL_DM_SEQ_ALIAS instead to have the flash on spi1 both on SPL and U-Boot proper. Changes since v1: - Changed bus number to 1 in SPL to match U-Boot proper (before it was bus 0 in SPL and bus 1 in U-Boot). - Generalization. v1 did a first soft_reset in 8_8_8_DTR but that wouldn't work since Pratyush Yadav fixed supports_op() in commit 5752d6ae8daacbd ("spi: spi-mem: add spi_mem_dtr_supports_op()"). So now we try a few protocols until 1_1_1 is supported by controller and device. Might work for more systems.
