Even with Dominik's great work, I suspect that PCMCIA may suffer the same problem as USB in this respect, and require a delay before trying to mount the root filesystem. We'll have to see when folk start using this. > Wishes and non-wishes: > * It would be nice to be able to replace the CF > without rebooting. That's an interesting one. Alan Cox may have done some work on IDE to resolve this, but there seems to be some issue preventing it (and Alan's other IDE patches) being merged. > * It can be assumed that the PC card CF adapter > is present during boot. > * There is no need to support hotplugging of the PC card CF adapter. > (i.e. the PC card CF adapter could be treated as a static, > builtin device, with its driver linked into the kernel). The CF adapter is a dumb piece of hardware which just converts the socket pins from PCMCIA format to CF format. It's completely transparent to software. In fact, software doesn't even know it's there. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core
