From 6c44b157e537fc3a3c2aa4732218a5341fd43387 Mon Sep 17 00:00:00 2001 From: Josef Schlehofer Date: Thu, 18 Nov 2021 16:37:17 +0100 Subject: mvebu: kernel: enable CONFIG_BLK_DEV_NVME CONFIG_BLK_DEV_NVME [1]: - This is a kernel driver for SSD connected to PCI or PCIe bus [1]. By default, it is enabled for targets "ipq807x", "rockchip/armv8" and "x86/64". With miniPCIe adapter, there is a possibility to connect NVMe disk to Turris Omnia (cortex-a9), Turris MOX (cortex-a53). It allows to boot system from NVMe disk, because of that it can not be kmod package as you can not access the disk to be able to boot from it. CONFIG_NVME_CORE [2]: - This is selected by CONFIG_BLK_DEV_NVME It does not need to be explicitly enabled, but it is done for "ipq807", "x64_64" and rockchip/armv8", which has also enabled the previous config option as well.
