Bootmenu on Nokia N900 is broken (on both HW and in qemu emulator). Bootmenu just prints garbage on the screen. I run git bisect and the result is:
72a0dd8bed010bef78028ae528763f9807758e6b is the first bad commit commit 72a0dd8bed010bef78028ae528763f9807758e6b Author: Simon Glass sjg@chromium.org Date: Fri Jan 6 08:52:29 2023 -0600
video: Enable VIDEO_ANSI by default only with EFI
This is not generally needed unless EFI_LOADER is used. Adjust the default setting to reduce the size of the U-Boot build.

Change was relatively simple:

On master branch with CONFIG_VIDEO_ANSI=y is bootmenu rendering again.
CONFIG_VIDEO_ANSI needs to be by default enabled also when CONFIG_CMD_BOOTMENU is enabled (not only for EFI).
Simon, would you fix it?
