AMD Hudson A55E: Remove GEC firmware blob kconfig prompt
The "gigabit ethernet controller" (GEC) block was added to AMD Hudson A55E to integrate ethernet capabilities into an AMD southbridge. The GEC is designed to work with B50610 and B50610M gigabit PHY chips from Broadcom. These parts may not be generally available in small quantities for embedded development. The GEC block requires an opaque firmware blob to function. The GEC blob is controlled by AMD and Broadcom and is not available from coreboot.org. This change removes GEC support from AMD Parmer and AMD Thatcher mainboards since these boards do not have the Broadcom PHY. AMD has requested that the GEC be hidden for Hudson FCH since the PHY parts are not generally available. This Kconfig option can make it appear that this is a viable and supported way to add Ethernet to an embedded board. It is possible to use the Hudson GEC block with other PHYs, but this requires development of a custom GEC blob and a custom Ethernet driver. A custom GEC blob has been developed for a Micrel PHY, but there is no accompanying driver.
