Subject: [PATCH] Eliminate user-selectable CONFIG_MV643XX_ETH_[012]

From: Dale Farnsworth <dale@...nsworth.org>

Remove the use of CONFIG_MV643XX_ETH_[012] variables on most
platforms.  Instead, platform-specific code enables the ports
supported by the hardware.  After this patch, these config
variables are only used in arch/ppc, so also move them from
drivers/net/Kconfig to arch/ppc/Kconfig.

Signed-off-by: Dale Farnsworth <dale@...nsworth.org>

---
It was a mis-feature that the supported ports were ever user-selectable.
Which ports the hardware supports should be specified by platform-specific
code, not by the user.
