Currently, the project is very badly stuck at mapping the registers
without that we can't configure the interrupts. We have tried
accessing the registers with both read/write_io_(x) and
map_physical_memory()[2](MMUIO) but both of them didn't work out,
either they are giving 0xffff or 0x0000(65535 or 0).
Not sure if it helps, but it seems eg. the Via driver is mapping
different things:
https://github.com/pdziepak/Haiku/blob/master/src/add-ons/kernel/drivers/graphics/via/driver.c#L385
Notice the use of di->pcii.u.h0.base_registers_pci, rather than
pciInfo->u.h0.base_registers in
your case. Maybe this is needed for SDHCI too? What is the difference between
these?
