Update the existing overlay which configures PCIE0 instance of PCIe on J721E-EVM in Endpoint mode of operation, in order to configure PCIE1 instance of PCIe as well in Endpoint mode of operation. Hence, change the name of the overlay to reflect its updated functionality. Signed-off-by: Siddharth Vadapalli <s-vadapalli@xxxxxx> --- Hello, This patch is based on linux-next tagged next-20240220.
