[U-Boot] is there really a "CONFIG_RAMBOOT" config option?

The  was added in commit 3a4ff8b3cd71 ("at91rm9200ek: add configure
target for RAM boot"). At the time there was a at91rm9200ek_ram target
that would enable this option. This appears to have survived through
to at91rm9200ek_ram_defconfig which has
CONFIG_SYS_EXTRA_OPTIONS="RAMBOOT" so yes CONFIG_RAMBOOT seems to be
perfectly valid for this board. Some of the other Freescale/NXP boards
also use RAMBOOT_PBL.

I think CONFIG_SYS_EXTRA_OPTIONS is on the list to be removed. Not
sure if anyone is actually working on it.
