right click-->search for--> all commands
type in there mov r32,dword ptr ds:[const]
and hit find

ollydbg will pop up another window with all those calls that matches the pattern

Code:

00401000   JMP SHORT OLLYDBG.00401012                (Initial CPU selection)
00401012   MOV EAX,DWORD PTR DS:[4B011B]             [004B011B]=00000000
00401066   MOV EAX,DWORD PTR DS:[4B0123]             [004B0123]=00000000
00401140   MOV EAX,DWORD PTR DS:[4B011B]             [004B011B]=00000000
004014EF   MOV ESI,DWORD PTR DS:[4CD280]             DS:[004CD280]=00000000
if you just prefer only those that are moved to eax
change the command to
mov eax,dword ptr ds:[const]
