Fix usage of CONFIG_PREBOOT

2022-11-21T14:23:00+00:00

Due to usage of PREBOOT in Kconfig, macro CONFIG_PREBOOT is always defined
when CONFIG_USE_PREBOOT is enabled. In case CONFIG_PREBOOT is not
explicitly enabled it is set to empty C string and therefore
'#ifdef CONFIG_PREBOOT' guard does not work. Fix this issue by introducing
a new Kconfig symbol PREBOOT_DEFINED which cause to define new C macro
CONFIG_PREBOOT_DEFINED only when CONFIG_PREBOOT is really defined.

Change usage of '#ifdef CONFIG_PREBOOT' by '#ifdef CONFIG_USE_PREBOOT' for
code which checks if preboot code would be called and by
'#ifdef CONFIG_PREBOOT_DEFINED' for defining preboot code.

vbe: Record which phases loaded using VBE

2022-10-31T15:04:00+00:00

We expect VPL and SPL to load using VBE. Add a record of this so we can
check it in U-Boot proper.

vpl: Allow signature verification

2022-10-31T15:04:00+00:00

Add the required Kconfig option so that signatures can be verified when
loading a configuration.

vbe: Add info about the VBE device to the fwupd node

2022-10-31T15:04:00+00:00

At present we put the driver in the /chosen node in U-Boot. This is a bit
strange, since U-Boot doesn't normally use that node itself. It is better
to put it under the bootstd node.

To make this work we need to copy create the node under /chosen when
fixing up the device tree. Copy over all the properties so that fwupd
knows what to do.

Update the sandbox device tree accordingly.

vbe: Add Kconfig options for VPL

2022-10-31T15:03:59+00:00

Enable the various features needed in VPL, by adding Kconfig options.

Update the defconfig for sandbox_vpl so that the build for each phase
includes what is needed. Drop LZMA for now and make sure partition support
is omitted in SPL, since it is not needed.

vbe: Drop the U-Boot prefix from the version

2022-10-31T15:03:36+00:00

We don't need the U-Boot prefix on the version and in fact it is harmful
since pytest gets confused seeing the U-Boot banner bring displayed when
the version is printed.

Drop the prefix from the string.

We could produce an entirely new string from the component parts, but this
adds to the rodata size and would break the use of version_string as the
only thing which holds this information.

vbe: Move OS implementation into a separate file

2022-10-31T15:03:36+00:00

Move this into its own file so it can be built only by U-Boot proper.

vbe: Support reading the next SPL phase via VBE

2022-10-31T15:03:18+00:00

Add an SPL loader to obtain the next-phase binary from a FIT provided
by the VBE driver.

vbe: Use a warning for a failed requests

2022-10-31T15:03:18+00:00

Optional requests should present a warning rather than an error. Update
the log call.

vbe: Rename vbe_fixup to vbe_request

2022-10-31T15:03:18+00:00

The vbe_fixup file handles device tree fixups, but these are called OS
requests in VBE. Rename the file to reflect its wider purpose.
