This adds a PCI UFS controller support and enables the support on
QEMU RISC-V for testing.

Requiring QEMU v8.2+.

This series is avaiable at u-boot-x86/ufs for testing.

Changes in v2:
- fix a build warning

Bin Meng (9):
  ufs: Correct the UFS terminlogy
  ufs: Add a line feed to the end of some dev_xxx() messages
  cmd: kconfig: Make ufs prompt look similar to other commands
  cmd: ufs: Correct the help text
  pci_ids: Add Red Hat vendor and device IDs
  ufs: Allow mmio registers on the PCI bus
  ufs: Add a PCI based UFS controller driver
  ufs: Handle UFS 3.1 controllers
  qemu: riscv: Enable UFS support

At present the 'ufs' command prompt does not look similar like other
commands. Update it.

Remove the additional space and use "sub-system" for consistency
with other commands like "scsi" and "usb".

Red Hat, Inc. donates a part of its device ID range [1] to QEMU,
to be used for virtual devices. This commit adds several typical
devices that are useful in U-Boot.

Check if the UFS controller is on the PCI bus, and get its register
base address accordingly.
