Instead of extending this, can we eventually clean this up and use C structs instead? U-Boot does not allow device accesses through a based plus offset notation.
Thanks for the review. I've given the clean-up a stab today, as a separate patch that the CuBox support series can build on.
u32 size, base, attrib;
+#ifdef MVUSB1_BASE
- u32 usb_base = (index == 0) ? MVUSB0_BASE : MVUSB1_BASE;
+#else
- u32 usb_base = MVUSB0_BASE;
+#endif
Can we please also avoid this #ifdef's ? Eventually you can use something like "base_0 + index * sizeof(struct usb_something)" ?
The two USB host controllers on Dove are separate entities at different base offsets (0x50000 vs. 0x51000). We could fill up the register struct to have a size of 0x1000, but then the next SoC to be supported could come up with a different offset.
Check drivers/usb/host/ehci-mxs.c for handling of such a case ;-)
