NVMe is a non-volatile storage media attached via PCIe.
As NVMe has much higher throughput than other block devices like
SATA it is a must have for RISC-V. Enable CONFIG_BLK_DEV_NVME.
The HiFive Unmatched is a board providing M.2 slots for NVMe drives.
Enable CONFIG_PCIE_FU740.

The EFI system partition uses the FAT file system. Many distributions add
an entry in /etc/fstab for the ESP. We must ensure that mounting does not
fail.
The default code page for FAT is 437 (cf. CONFIG_FAT_DEFAULT_CODEPAGE).
The default IO character set is "iso8859-1" (cf. CONFIG_NLS_ISO8859_1).
So let's enable NLS_CODEPAGE_437 and NLS_ISO8859_1 in defconfig.

Thanks, these are on for-next.
