Hmm, I added, the following options to my config file.

<snip> /* pass open firmware flat tree */ #define CONFIG_OF_FLAT_TREE 1

/* maximum size of the flat tree (8K) */ #define OF_FLAT_TREE_MAX_SIZE 8192

#define OF_CPU "PowerPC,MPC875" #define OF_TBCLK (CFG_8xx_CPUCLK_MAX / 16) #define CONFIG_OF_HAS_BD_T 1 #define CONFIG_OF_HAS_UBOOT_ENV 1 <snip>

make generates an error for oftree_dtb since it and oftree_dtb_len don't seem to be defined _at_all_ anywhere in U-Boot aside from four extern declarations.

My git HEAD is 392c252efd5d2e67b47ebeb3b7e4f42e7e3d5127 which I fetched roughly five minutes ago.

Have I broken my sources somehow, should I be declaring these two variables a header/source file that is board-specific, or is this a genuine error ? I admit to having a-minimally-functional-understanding (tm) of git and a <= 48 hour awareness of OpenFirmware generally so, I might have caused this somehow.

I notice this posting

http://patchwork.ozlabs.org/linuxppc/patch?id=2237 , do I need the two named files to get OpenFirmware compiling with U-Boot ?

?confused?
