[Bug 2140344] Re: [SRU] drivers/usb/cdns3 module path missing

[Heinrich Schuchardt]

With initramfs-tools (0.142ubuntu25.8) the following files are included
in the initrd on riscv64:

./usr/lib/modules/6.17.0-14-generic/kernel/drivers/usb/cdns3
./usr/lib/modules/6.17.0-14-generic/kernel/drivers/usb/cdns3/cdns3-pci-wrap.ko.zst
./usr/lib/modules/6.17.0-14-generic/kernel/drivers/usb/cdns3/cdns3-starfive.ko.zst
./usr/lib/modules/6.17.0-14-generic/kernel/drivers/usb/cdns3/cdns-usb-common.ko.zst
./usr/lib/modules/6.17.0-14-generic/kernel/drivers/usb/cdns3/cdnsp-udc-pci.ko.zst
./usr/lib/modules/6.17.0-14-generic/kernel/drivers/usb/cdns3/cdns3.ko.zst

The Milk-V Mars CM Lite is able to boot from USB.

Bug description:
  [ Impact ]

  The RISC-V StarFive JH7110 SoC uses the drivers in drivers/usb/cdns3
  for booting from USB. Some JH7110 have no SD-card (e.g. Milk-V Mars CM
  eMMC). We need USB support for installation.

  [ Test Plan ]

  Check that on riscv64 the following modules are included into the
  initrd when running update-initramfs:

  * cdns3_starfive
  * cdns_usb_common
  * cdns3

  Check that booting from USB on a JH7110 board is possible with the
  initrd.

  [ Where problems could occur ]

  If there were a syntax error, creation of initrds might fail.
  The addition of further drivers increases the initrd size.
  Module dependencies for the cdns3 driver might be missing in the initrd.

  [ Other Info ]
