27 * "(CONFIG_SYS_MEM_SIZE - CONFIG_SYS_RESERVE_MEM_SIZE)" has been used in
28 * u-boot nanopi2-v2016.01.
29 * This is not working anymore because boot_fdt_add_mem_rsv_regions() in
30 * common/image-fdt.c has been extended:
31 * Also reserved-memory sections are marked as unusable.
32 *
33 * In friendlyArm Ubuntu 16.04 source arch/arm/boot/dts/s5p4418.dtsi:
34 * reserved-memory {
35 * #address-cells = <1>;
36 * #size-cells = <1>;

42 * };

45 * arch_lmb_reserve() of arch/arm/lib/bootm.c:
46 * "Allocate space for command line and board info - ... below the current
47 * stack pointer."
48 * --> Memory allocated would overlap with "secure_memory@b0000000"
49 * --> lmb_add_region(rgn, base==0xb0000000, size==0x1000000) fails,
50 * boot output:
