Enable platforms to omit some bootloaders
If a platform doesn't specify a BLx_SOURCE variable, then building of the corresponding bootloader isn't attempted. Also allow BL3-3 to be omitted from the FIP. Note, this change also removes support for PLAT=all and the 'fip' target from the 'all' recipe. Fixes ARM-software/tf-issues#30 Change-Id: Ibdfead0440256eaf364617ecff65290ca6fe6240 Signed-off-by: Jon Medhurst <tixy@linaro.org>
