From 1cf407b4f8d56035816efaf936a40553441eca46 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Fri, 10 Nov 2017 20:18:23 +0100 Subject: spi_master: Introduce SPI_MASTER_4BA feature flag Add a feature flag SPI_MASTER_4BA to `struct spi_master` that advertises programmer-side support for 4-byte addresses in generic commands (and read/write commands if the master uses the default implementations). Set it for all masters that handle commands address-agnostic. Don't prefer native 4BA instructions if the master doesn't support them.
