I'm just curious about the size here: how it ended up as 0x0338?
While looking at the TRM of AM335x I can come up with 0x0238 (0x44e10800 -
0x44e10a38), but I don't see any sings of the remaining 0x0100 to be
documented at least.

No, pinmux registers are available till 0x44E10B38, look at AM335x latest TRM
or pinmux utility (we cannot find the exact offsets but pins we can find after
0x0A38, conf_ddr_resetn) at http://www.ti.com/tool/pinmuxtool

If you have a hole inbetween the registers it sounds like you also have core and
wkup domains? In that case those should be set up as separate controllers as other
SCM registers may be inbetween those domains.
