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.

drivers/mtd/nvmxip: introduce QSPI XIP driver add nvmxip_qspi driver under UCLASS_NVMXIP The device associated with this driver is the parent of the blk#<id> device nvmxip_qspi can be reused by other platforms. If the platform has custom settings to apply before using the flash, then the platform can provide its own parent driver belonging to UCLASS_NVMXIP and reuse nvmxip-blk driver. The custom driver can be implemented like nvmxip_qspi in addition to the platform custom settings. Platforms can use multiple NVM XIP devices at the same time by defining a DT node for each one of them.
