[U-Boot-Users] get_timer on ppc and bugs related to calling it (fsl_i2c)

[Kumar Gala]

In debugging moving the bss outside of the image on 85xx I run into in  
issue with the SPD code using fsl_i2c before we are running in ram and  
setup the BSS.

It looks like i2c_wait4bus() [in fsl_i2c.c] calls get_timer().

get_timer implemented in lib_ppc/interrupts.c and uses a global  
timestamp that exists in the BSS.  This seems pretty bad in that we  
have been just getting a bogus value for timestamp out of flash.   
Luckily we don't write timestamp until interrupts are enabled and at  
that point we've relocated to memory.

However it seems like fsl_i2c.c should NOT be using get_timer().  Is  
there another global interface to get relative time that we can just  
use time base for?
