Qemu with the secure extension enabled will insert a secram node into
the device tree:
secram@e000000 {
secure-status = "okay";
status = "disabled";
reg = <0x0 0xe000000 0x0 0x1000000>;
device_type = "memory";
};
Barebox would previously parse this node, add it as a memory bank and
than reinsert an enabled node into the fixed up device tree.
Fix this by skipping disabled memory nodes.
