[U-Boot] MPC5121 MSCAN Peripheral in U-Boot

[Matteo Canella]

Hi Wolfgang,
I need the CAN driver in the boot loader because I need to handle a CAN
request in a very short time...
I doubt I can boot Linux and make the CAN driver work in the order of a few
hundreds of milliseconds...

What would be the purpose of such a driver? In the boot loader?

Wouldn't it make much more sense to focus on accelerating the Linux
boot time and use the existing socketcan driver there?

Best regards,
