mpc85xx/T4240EMU: Remove T4240EMU board

T4240 SoC has been available for a long time. Emulator support is no longer needed.

Applied to u-boot-mpc85xx master. Awaiting upstream.

I wonder if such emulator support is generally usable for custom made boards using T4240? If so I think you should leave in u-boot, possibly adjust it so it is usable for other boards too.

Jocke,

Emulator "board" is highly customized to fit the capacity of such emulator platform. This board was added to support early adopters with Freescale support. After rev2 SoC was released, such support was dropped and no effort has been made to continue supporting emulator model.

Customers are welcome to use T4240QDS as a reference design. It is a fraction of the cost of an emulator system, and it runs thousands times faster.

Given the availability of emulator model, QDS board (and RDB board) and the performance, I believe there is no user of T4240EMU board.
