[U-Boot] [PATCH v5 12/14] jetson-tk1: Add PSCI configuration options and reserve secure code

[Jan Kiszka]

From: Ian Campbell 

The secure world code is relocated to the MB just below the top of 4G, we
reserve it in the FDT (by setting CONFIG_ARMV7_SECURE_RESERVE_SIZE) but it is
not protected in h/w. See next patch.
