13Description
14-----------
15
16The seama command is used to load and decode SEAttle iMAges from NAND
17flash to memory.
18
19This type of flash image is found in some D-Link routers such as
20DIR-645, DIR-842, DIR-859, DIR-860L, DIR-885L, DIR890L and DCH-M225,
21as well as in WD and NEC routers on the ath79 (MIPS), Broadcom
22BCM53xx, and RAMIPS platforms.
23
24This U-Boot command will read and decode a SEAMA image from raw NAND
25flash on any platform. As it is always using big endian format for
26the data decoding is always necessary on platforms  such as ARM.

28dst_addr
29    destination address of the byte stream to be loaded
30
31index
32    the image index (0, 1, 2..) can be omitted

48Configuration
49-------------
50
51The command is available if CONFIG_CMD_SEAMA=y.
52
53Return value
54------------
55
56The return value $? is set 0 (true) if the loading is succefull, and
57is set to 1 (false) in case of error.
58
59The environment variable $seama_image_size is set to the size of the
60loaded SEAMA image.
