[U-Boot] printf("%d") breaks u-boot 2015.01+

Hi!

In u-boot 2015.04-rc, as soon as execution hits printf("%d"), it hangs. (Usually, that's after "DRAM: " message).

Now, I have to admit I'm chainloading u-boot from

U-Boot 2013.01.01 (Mar 25 2015 - 15:57:21)

tftp 0x01000040 .../u-boot.bin Waiting for PHY auto negotiation to complete.. done ENET Speed is 100 Mbps - FULL duplex connection Using mii0 device TFTP from server 10.0.0.6; our IP address is 10.0.0.99 ... Bytes transferred = 325004 (4f58c hex) # go 0x01000040

...but that worked well for 2014.10, (and is nearly mandatory in my config).

I'm using cross-compiler from eldk-5.6, but eldk-5.4 crosscompiler produces same behaviour, and both seem to work for 2014.10.

Any ideas?

Thanks, Pavel
