[PATCH] mmc: mmc_mxc: Allow selection only for the correct platforms

From: Fabio Estevam <hidden>
Date: 2011-01-20 17:02:59

Currently MMC_MXC driver can be selected by all i.MX devices.

Restrict its use only for the appropriate processors.

I would prefer to let the architectures explicitly in Kconfig.

If someone selects IMX_HAVE_PLATFORM_MXC_MMC by mistake on a MX51 board, it will be possible to select the MXC_MMC driver in the kernel for MX51, which is incorrect.

Using the approach of explicitly marking the architectures that support MXC_MMC would avoid such problems as well.

Not likely to happen. 

Thanks,

it's not optimal, but nothing happens unless this someone registers a
corresponding device, too.

I wouldn't bet ...

Note I don't argue, if you still prefer the explicit list it's OK for
me.

Thanks for the ping -- I've pushed this to mmc-next with Sascha's ACK now.
