Some devices keep 2 copies of the bootloader_message in the misc
partition and write each in sequence when updating. This ensures that
there is always one valid copy of the bootloader_message. Teach u-boot
to optionally try a backup bootloader_message from a specified offset if
the primary one fails its CRC check.

It is is sometimes desired to be able to skip decrementing the number of
tries remaining in an Android A/B boot, and instead just check which
slot will be tried later. This can commonly be be the case for platforms
that want to A/B u-boot itself, but are required to boot from a FAT MBR
partition. In these cases, u-boot must do an early check that the MBR
points to the correct A/B boot partition, and if not rewrite the MBR to
point to the correct one and reboot. Decrementing the try count in this
case is not desired because it means that each u-boot might constantly
ping-pong overwriting the MBR and rebooting until all the retries are
used up.

Some Linux parameters can be set automatically by U-Boot, if it knows the
device being used. For example, since U-Boot knows the serial console
being used, it can add parameters for earlycon and console.
Add support for this.
Note that this is an experimental feature and we will see how useful it
turns out to be. It is very handy for ChromeOS, since otherwise it is very
difficult to manually determine the UART address or port number,
particularly in a script.

At present only a single menu is supported. All items are shown and a
pointer object points to the current item.
Add support for multiple menus, one of which is highlighted, indicated
by the highlight_id property in the scene.
The highlighted menu item has a SCENEOF_POINT flag, indicating that it
is currently pointed to.
The popup menu is normally closed, in which case it shows only the
current menu item. When it is opened, it shows all items, allowing the
user to select one.
Rather than requiring the menu item to have a description, require it to
have a label. Use the label (only) for the popup menu.
With this, most of the drawing and layout logic is complete.
Signed-off-by: Simon Glass <sjg@chromium.org>
The current implementation supports a 'pointer' object which points to
the currently highlighted menu item. We want to support highlighting the
label of the menu item instead, e.g. with inverse video. In this case we
will need to 'unhighlight' the old item and highlight the new one.
As a first step, move the pointer logic into a function. This fixes a
bug where the item is hidden when it should not be.
