From: Dinh Nguyen <redacted> The SOCFPGA's SMP code uses 0x0 for as the location for the trampoline to bring secondary cores online. This patch adds a /memreserve/ section to reserve the first 4K for the SMP trampoline code.

Actually, comment here explaining that ROM code uses 0x0 for the trampoline would be nice here... if I understand it correctly.
