[U-Boot] Boot failure - Latest master and Raspberry Pi

Previous I've added these two definitions to use u-boot witht he raspberry pi, into include/configs/rpi.h

#define CONFIG_SYS_MAXARGS              32      /* dch doubled from 16    */ #define CONFIG_SYS_BARGSIZE             1540    /* dch added, default 512 */

However on the most recent master, the raspberry pi fails to boot with or without these definitions.

Two questions:

1. How to I determine where the pi's use of u-boot is failing? I don't even get the 2 second countdown before u-boot runs bootcmd.

2. Are these constants still effective in the current master? If not are there replacements?

Thanks
