Add img2simg tool that splits a large image into <n> sparse files
img2simg can take a large binary and chop it into multiple sparse
images. Each sparse image that is output has two chunks: a Don't
Care chunk to offset to where the data should be placed, and a
Raw chunk that actually contains the data to be placed there.
So, for example, if you have a 12 GB random file that you want to
place into userdata for testing e-MMC, you can run img2simg on it
to chop it into multiple sparse files and then "fastboot flash
userdata" on each of the sparse files.
Usage: img2simg [OPTIONS] <raw_image_file>
The <raw_image_file> will be split into as many sparse
files as needed. Each sparse file will contain a single
DONT CARE chunk to offset to the correct block and then
a single RAW chunk containing a portion of the data from
the raw image file. The sparse files will be named by
appending a number to the name of the raw image file.
OPTIONS (Defaults are enclosed by square brackets):
-s SUFFIX Format appended number with SUFFIX [%03d]
-B SIZE Use a block size of SIZE [4K]
-C SIZE Use a chunk size of SIZE [64M]
SIZE is a decimal integer that may optionally be
followed by a suffix that specifies a multiplier for
the integer:
c 1 byte (the default when omitted)
w 2 bytes
b 512 bytes
kB 1000 bytes
K 1024 bytes
MB 1000*1000 bytes
M 1024*1024 bytes
GB 1000*1000*1000 bytes
G 1024*1024*1024 bytes
