Add this\nentry under a CONFIG_IS_ENABLED(PCIE_DW_AMD) guard so it is only\nincluded when the PCIe driver is configured. VERSAL2_MEM_MAP_USED is\nadjusted from 5 to 6 accordingly, keeping the DRAM bank index correct.\n\nSigned-off-by: Pranav Sanwal <pranav.sanwal@amd.com>\n---\n arch/arm/mach-versal2/cpu.c | 16 +++++++++++++++-\n 1 file changed, 15 insertions(+), 1 deletion(-)",
