From f37af2760ea92cec3fbdcfceb6df7be57a618165 Mon Sep 17 00:00:00 2001 From: Abdellatif El Khlifi Date: Mon, 17 Apr 2023 10:11:52 +0100 Subject: drivers/mtd/nvmxip: introduce NVM XIP block storage emulation add block storage emulation for NVM XIP flash devices Some paltforms such as Corstone-1000 need to see NVM XIP raw flash as a block storage device with read only capability. Here NVM flash devices are devices with addressable memory (e.g: QSPI NOR flash). The implementation is generic and can be used by different platforms. Two drivers are provided as follows. nvmxip-blk : a generic block driver allowing to read from the XIP flash nvmxip Uclass driver : When a device is described in the DT and associated with UCLASS_NVMXIP, the Uclass creates a block device and binds it with the nvmxip-blk. Platforms can use multiple NVM XIP devices at the same time by defining a DT node for each one of them.
