Hi list,
This pair of patches is a byproduct of discussion on my earlier patchset (Patchwork series #357953), which had simply disabled this initialization where SUNXI_SRAMC_BASE was set to null. It is true that this initialization is not needed on newer devices, but not because the SRAMC (now called "SYSCON") has been removed, so a null SRAMC base was not the appropriate fix.
Of the two patches here, only the first is an actual fix; the second is a mostly-cosmetic cleanup, which also adds a TODO to make this function independent of SUNXI_SRAMC_BASE altogether, per the aforementioned prior discussion.
I do not have an A10, A10s, A13, GR8, or A20 against which to test this change; a reviewer with access to one of these should verify that USB-OTG functionality is still working. That ought to be a sufficient regression test. :)
A note to committers: If patch 1 is acceptable but patch 2 is not, go ahead and commit only patch 1 (unless the U-Boot project specifically avoids doing this).
Thanks for your time, Sam
