This patch cleans out a lot of unused variables in the ARM Kconfig files and introduces CONFIG_RAMSTAGE_BASE which is similar to CONFIG_RAMBASE on x86. This gets rid of the hard coded assumption that on ARM coreboot is always executed at the lowest DRAM address. But in fact, this might not be true because we might want coreboot to live at the end of RAM, or in SRAM Change-Id: I03e992645f9eb730e39a521aa21f702959311f74 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: https://chromium-review.googlesource.com/168645 Reviewed-by: David Hendrix <dhendrix@chromium.org> Tested-by: David Hendrix <dhendrix@chromium.org> (cherry picked from commit 15b87892eb2d5e27759c49dc6c8c7e626f651d77) Signed-off-by: Isaac Christensen <isaac.christensen@se-eng.com> Reviewed-on: http://review.coreboot.org/6634 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
