解決"UBoot Failed to map physical memory"問題
參考資訊:

問題如下(將SPI Flash讀取到0x00000000的位置):
=> sf read 0 0 1024 device 0 offset 0x0, size 0x1024 Failed to map physical memory
解法如下(UBoot不允許Map記憶體0x00000000,但是可以使用cp.b複製到0x00000000):
=> sf read 0x80000000 0 1024 device 0 offset 0x0, size 0x1024 SF: 4132 bytes @ 0x0 Read: OK => cp.b 0x80000000 0 1024
