[Bug 1905274] Re: enable u-boot spl for riscv64

[Dimitri John Ledkov]

Groovy will not receive these changes. There will not be a point release
of groovy to make a new image. Focal images will be provided at next
point release which will only be supported to upgrade to hirsute or next
LTS.

** Description changed:

- enable u-boot spl for riscv64
+ [Impact]
  
- 1) backport opensbi 0.8 to focal
- https://bugs.launchpad.net/ubuntu/focal/+source/opensbi/+bug/1905456
+  * To build bootable uboot-sifive package, it must be built with
+ opensbi. Currently those are missbuilt and not packaged.
  
- 2) build u-boot with opensbi specified
+ [Test Case]
  
- 3) ship uboot-spl in the cloud image
+  * Download u-boot buildlog for riscv64
+ 
+ and Look for:
+ 
+ /<<PKGBUILDDIR>>/"arch/riscv/lib/mkimage_fit_opensbi.sh" \
+ arch/riscv/dts/hifive-unleashed-a00.dtb > u-boot.its
+ WARNING: OpenSBI binary "fw_dynamic.bin" not found, resulting binary is not functional.
+ 
+ 
+ * A missbuilt package will have the Warning emitted by mkimage_fit_opensbi.sh, whereas fixed u-boot package will not.
+ 
+ * Check that uboot-sifive riscv64 .deb provides
+ 
+ ./usr/lib/u-boot/sifive_fu540/u-boot-spl.bin
+ ./usr/lib/u-boot/sifive_fu540/u-boot.bin
+ ./usr/lib/u-boot/sifive_fu540/u-boot.itb
+ ./usr/lib/u-boot/sifive_fu540/uboot.elf
+ 
+ As those will be consumed by livecd-rootfs when building bootable
+ preinstalled images.
+ 
+ [Where problems could occur]
+ 
+  * u-boot build embedds FU540 dtb and OpenSBI at a particular interface
+ versions. It is unknown if these components will be compatible with
+ future board revisions or may require changes and rebuilds. Specifically
+ kernel interfaces with opensbi and uboot and hardware and has certain
+ dtb expectation. Currently it has been verified that the dtb vendored in
+ opensbi u-boot and kernel are all identical. But hardware issues may
+ arise when these will change out of sync - for example opensbi installed
+ shutdown/reboot handler resulting in a reboot hang.
+ 
+ I expect all of these components needing changes and rebuilds to support
+ FU740.
+ 
+ [Other Info]
+  
+  * Anything else you think is useful to include
+  * Anticipate questions from users, SRU, +1 maintenance, security teams and the Technical Board
+  * and address these questions in advance
