It's been quite a while, but I remember when porting RZ/A1 code that
without those two functions, things didn't work right. Of course that was
many releases ago.
However, one thing that I know I need is
+ .l2c_aux_val = 0,
+ .l2c_aux_mask = ~0,
Without that, I don't get my L2C driver loaded.
Hence:
a96bb197693e ("ARM: 8660/1: shmobile: r7s72100: Enable L2 cache")
So at least for now, I would say I still need the setup file.
