*
* Description:

* NOR/SRAM2 base address (0x64000000)
*
* General transaction rules. The requested AHB transaction data size can be 8-,
* 16- or 32-bit wide whereas the SRAM has a fixed 16-bit data width. Some simple
* transaction rules must be followed:
*
* Case 1: AHB transaction width and SRAM data width are equal
* There is no issue in this case.
* Case 2: AHB transaction size is greater than the memory size
* In this case, the FSMC splits the AHB transaction into smaller consecutive
* memory accesses in order to meet the external data width.
* Case 3: AHB transaction size is smaller than the memory size.
* SRAM supports the byte select feature.
* a) FSMC allows write transactions accessing the right data through its
* byte lanes (NBL[1:0])
* b) Read transactions are allowed (the controller reads the entire memory
* word and uses the needed byte only). The NBL[1:0] are always kept low
* during read transactions.
