+** !!!! VERY IMPORTANT NOTICE !!!! FLASH DATA STORED IN LITTLE ENDIAN FORMAT
|
||||
+**
|
||||
+** This module contains the Serial Flash access routines for the Atheros SOC.
|
||||
+** The Atheros SOC integrates a SPI flash controller that is used to access
|
||||
+** serial flash parts. The SPI flash controller executes in "Little Endian"
|
||||
+** mode. THEREFORE, all WRITES and READS from the MIPS CPU must be
|
||||
+** BYTESWAPPED! The SPI Flash controller hardware by default performs READ
|
||||
+** ONLY byteswapping when accessed via the SPI Flash Alias memory region
|
||||
+** (Physical Address 0x0800_0000 - 0x0fff_ffff). The data stored in the
|
||||
+** flash sectors is stored in "Little Endian" format.
|
||||
+**
|
||||
+** The spiflash_write() routine performs byteswapping on all write
|
||||
+** operations.
