[U-Boot-Users] TI PCI1620 PC Card Controller

[David Clark]

Does anyone have experience supporting the TI PCI1620 PC Card Controller
in U-boot and Linux?  I am working with a custom board that uses this
controller.  I am able to use 32-bit Cardbus card in Linux but not
16-bit cards.  The error I get is "unable to allocate memory" but I have
traced it down to the kernels inability to access the CIS on 16-bit
cards.  I believe that the PCI1620 is not being configured correctly to
allow access.  It is my understanding that it is U-Boot's responsibility
to setup the controller.  The PCI1620 contains ExCA Compatible Registers
that are register-compatible with the Intel 82365.  I have found that
U-boot has a driver for the 82365 so is it as simple as configuring
U-Boot to use this driver?  That is the path that I'm going to explore
but if anybody with past experience can offer some guidance it would be
mush appreciated.
