 ${mtdparts}; nand read.e 0x32000000 kernel 0x200000; bootm 0x32000000

 Nice work -- one thing though you have to protect the ; with backslash
 escaping, and the $ too.  That'll be why it booted on pressing enter, it
 took the ; as command separator and finished the setenv after the first ;
 then did the other commands in order.

 If you confirm you have the escaping right, you can use

 saveenv

 command to store the changed environment in NAND, then you don't need to
 do this each boot.

 AFAIK slowing the SD CLK is the only way to impact this timeout issue for
 the slow cards, because we already max out the timeout allowed by the
 Glamo internal register.  Since it counts SD Card clocks we can work
 around slow absolute card performance by slowing the clock.
