"""QFIL tools for qualcomm IC based on https://github.com/bkerler/edl
by LyuOnLine
QFIL tools for qualcomm ICs.
- Detail logs for sahara and firehose communications.
- Support config xml file samed as qualcomm tools.
Args:
- firehose： firehose images, such as prog_firehose_ddr.elf.
- rawprogram : rawprogram config xml, such as rawprogram_unsparse.xml or rawprogram*.xml.
- patch : patch config xml, such as patch0.xml or patch*.xml.
- imagedir : directory name of images resides.
