We want to read and write the card's DMA through PCIe
There are some problems we met.
1. Is it okay for us to use XDMA to achieve this goal?
2. Why does the XDMA interrupt_out affect kernel booting? And how can we debug?
After kernel config the following item
-> PCI host controller drivers
-> Xilinx XDMA PL PCIe host bridge support
Kernel booting will hang up on the console_init()
