[U-Boot] A question in lowlevel_init.S

[krrish53]

Hello everybody,
I have a question pertaining to almost every lowlevel_init.S. The code goes
like

/*make r0 relative the current location so that it*/
/*reads SMRDATA out of flash rather than memory*/
ldr r0,=SMRDATA
ldr r1,_TEXT_BASE
sub r10,r0,r1

I couldn't relate the code to comments made ahead of that. I tried for quite
sometime but it went in vain.  Please enlighten me. I would greatly
appreciate any response.

Thanks,
Vamsi
