+Flash programming on the INCA-IP board is complicated because of the
+EBU swapping unit. A BDI2000 can be used for flash programming only
+if the EBU swapping unit is enabled; otherwise it will not detect the
+flash memory. But the EBU swapping unit is disadbled after reset, so
+if you program some code to flash with the swapping unit on, it will
+not be runnable with the swapping unit off.
+
+The consequence is that you have to write a pre-swapped image to
+flash using the BDI2000. A simple host-side tool "inca-swap-bytes" is
+provided in the "tools/" directory. Use it as follows:
+
+ bash$ ./inca-swap-bytes <u-boot.bin >u-boot.bin.swp
+
+Note that the current BDI config file _disables_ the EBU swapping
+unit for the flash bank 0. To enable it, (this is required for the
+BDI flash commands to work) uncomment the following line in the
+config file:
+
+ ;WM32 0xb8000260 0x404161ff ; Swapping unit enabled
+
+and comment out
+
+ WM32 0xb8000260 0x004161ff ; Swapping unit disabled
+
+Alternatively, you can use "mm 0xb8000260 <value>" commands to
+enable/disable the swapping unit manually.
+
+Just for reference, here is the complete sequence of actions we took
+to install a U-Boot image into flash.
+
+ 1. ./inca-swap-bytes <u-boot.bin >u-boot.bin.swp
+
+ 2. From BDI:
+
+ mm 0xb8000260 0x404161ff
+ erase 0xb0000000
+ erase 0xb0010000
+ prog 0xb0000000 /tftpboot/INCA/u-boot.bin.swp bin
+ mm 0xb8000260 0x004161ff
+ go 0xb0000000
