Have you tried going to the Command Prompt and using do in32 <address>
ie
>\do in32 44E10950 (Return)
Running thru some of the SPI0 pads gave the following
conf_spi0_sclk = 0x44E10950 = 0x00000020
conf_spi0_d0 = 0x44E10954 = 0x00000020
If you type
\>do ?
you get a list of available commands
(note \> is the prompt and not to be typed)
