A problem about EMMC support

[SlarkXiao]

When flash a partition with 'sparse="true"' flag, no error returned. But device can't boot up successfully and it reports corresponding partition mount failed. According to the Windows tool, it has split image up into 4 partitions and then write 1 by 1. It seems we don't obtain such mechanism.

Test log as below from windows QFIL: xml: <program start_sector="3031040" size_in_KB="262144.0" num_partition_sectors="524288" filename="system.img" sparse="true" start_byte_hex="0x5c800000" label="system"/>

QFIL log: INFO: File system.img is a sparse file, being split up into 4 separate XML tags ...... INFO: system.img is a sparse image

Actually this is issue was caused by the sparse image format. We shall transfer it to RAW image format.

Sparse image support has been implemented since the time this issue was opened. Please file new issue if problem remains.
