seama command
=============
Synopsis
--------
::
seama <dst_addr> <index>
Description
-----------
The seama command is used to load and decode SEAttle iMAges from NAND
flash to memory.
This type of flash image is found in some D-Link routers such as
DIR-645, DIR-842, DIR-859, DIR-860L, DIR-885L, DIR890L and DCH-M225,
as well as in WD and NEC routers on the ath79 (MIPS), Broadcom
BCM53xx, and RAMIPS platforms.
This U-Boot command will read and decode a SEAMA image from raw NAND
flash on any platform. As it is always using big endian format for
the data decoding is always necessary on platforms such as ARM.
dst_addr
destination address of the byte stream to be loaded
index
the image index (0, 1, 2..) can be omitted
Example
-------
::
=> seama 0x01000000
Loading SEAMA image 0 from nand0
SEMA IMAGE:
metadata size 36
image size 8781764
checksum 054859cfb1487b59befda98824e09dd6
Decoding SEAMA image 0x01000040..0x01860004 to 0x01000000
Configuration
-------------
The command is available if CONFIG_CMD_SEAMA=y.
Return value
------------
The return value $? is set 0 (true) if the loading is succefull, and
is set to 1 (false) in case of error.
The environment variable $seama_image_size is set to the size of the
loaded SEAMA image.
