7 title: Qualcomm External Bus Interface 2 (EBI2)
11 external memory (such as NAND or other memory-mapped peripherals) whereas
14 As it says it connects devices to an external bus interface, meaning address
15 lines (up to 9 address lines so can only address 1KiB external memory space),
25 Also CS1 and CS2 has -A and -B signals. Why they have that is unclear to me.

32 CS1 GPIO39 (A) / GPIO123 (B) 0x1b000000-0x1b800000 (8MB)
