thank you
as a small improvement (i've recently experienced), menu->active should be checked against menu->count (at the end of bootmenu_create), else it can be "outside" of the menu and selection is not visible till menu->active is below menu->count.
http://git.denx.de/?p=u-boot.git;a=blob;f=cmd/bootmenu.c;h=979ac4a638df48b9552feb82dd80ddbe74e69b8e;hb=f7bb20a53e829ce0b4d3c22c704e80b490d24016#l353
but i'm not 100% sure, how to handle it correctly, so i post it for discussion
because menu->active is initialized with 0 my preferred version is this:
if (menu->active >= menu->count)
menu->active=0; //or any other value below menu->count (maybe a const set by boardconfig, but this can also be outside the menu, so 0 is imho better)
this is a user-configured environment-var so it is not a big problem :) but a simple check avoids this issue
regards Frank
