Hi, Kyungmin Park! Thank you for patch! But I have a question - how should I apply it? Sorry, I'm not very skilled in UNIX/Linux. I've saved all code from:
diff --git a/common/cmd_onenand.c b/common/cmd_onenand.c index 9090940..2b8f01b 100644
to:
if (arg_off_size(argc - o, argv + o, &ofs, &len) != 0)
into "1.patch" file. Tryed to patch -p1 < /1.patch from U-Boot directory, and get:
patching file common/cmd_onenand.c patch: **** malformed patch at line 6: return (*p != '\0' && *endptr== '\0') ? 1 : 0;
I use U-Boot2009.08.rc2.
What is wrong? Or maybe you could send me your full /common/cmd_onenand.c ?

Now OneNAND handles block operation only. With this patch OneNAND handles all read/write size.
