mic2563 dual slot pcmcia controller

I have 2.4.18 kernel, and is booted by u-boot 0.4. However, I do not think
that I should do any init of pcmcia controller from the u-boot, because
u-boot does not use it and hence should not init it. I want to init it
inside the kernel. I thought m8xx_setup.c and m8xx_pcmcia.c is a better
place to do all my chip select for controlling mic2563 and the other pcmcia
related settings.

I did setup the second PCMCIA Slot on a MPC855. The bootloader (u-boot)
setups the pbrX, porX, ... registers. The kernel lives with this values.
Which Kernel do you have? For me was the /drivers/ide/ide-m8xx.c the most
important file (I needed CF support).

Betreff: mic2563 dual slot pcmcia controller


I have a mpc8xx based board, which has two pcmcia slots, and uses micrel
2563a power controller. Now, I understand that I have to control this in the
file drivers/pcmcia/m8xx_setup.c file. I was wondering if anybody has done
the same and can tell me what is the right way. Also, where do I set the
other pcmcia related values for example pbr0, memory size etc? Any pointers
would be helpful.

Thanks in advance.
