mic2563 dual slot pcmcia controller

mic2563 dual slot pcmcia controller

[Lokesh Kumar]

Hi,

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.

Yes, the power controller code is board specific. I don't remember much of
it today, but I don't think I've used a power controller like that.
The pcmcia related registers like pbr0 are setup by the m8xx_setup.c-code
dynamically, so there should be no need to mess with registers like that.
Please note that the pcmcia hardware in the m8xx series is kind of limited
if you use it with two slots, see the source code for more info.

Hope this helps!

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.

Hello

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).

Cheers

Can somebody point to a similar driver code, to control mic2563, which is
memory mapped on mpc8xx board, with cs#4 as chip select? Any template driver
code would be helpful as well.
