the top level logic tries hard to find a good LDSCRIPT default.  do you need 
to set this yourself anymore ?

if this is coming from the linker script, then it should be:
extern char __bss_end[];

pretty sure you dont need this anymore as common/cmd_version.c takes care of 
it.  so just delete this code.

err, is that barrier really needed ?  sounds like a bug in your compiler.

as for the memset, it should be:
memset((void *)gd, 0, GENERATED_GBL_DATA_SIZE);

sizeof(bd_t) -> GENERATED_BD_INFO_SIZE

this shows up multiple times

also, did i miss something, or do you not zero out your board info ?

> +	addr_sp -= sizeof(gd_t);

sizeof(gd_t) -> GENERATED_GBL_DATA_SIZE

this shows up multiple times
