Modification info

1. can work with Official SPRD U2S Diag Driver

2. after send FDL2(uboot), you need exec before using any fdl2 related command

3. (brom stage: set BEFORE send fdl1 by exec_addr 0x1234 ) overwrite an addr in stack AFTER sending fdl1 (to skip sign check of fdl1 in brom)

4. (win sprd driver only) (brom stage or FDL2 stage) set baudrate by baudrate rate

   according to researchdown，supported baudrates are 57600,115200,230400,460800,921600,1000000,2000000,3250000,4000000

   while in littlekernel code, only 115200, 230400, 460800, 921600 are listed (maybe it's internal value in lk, not for usb transfer)

5. interactive mode

6. (on emmc/ufs) auto detect sector size when reading partition list

7. (on nand) support read ubi part and calculate size according to nand 4th id, use nand_id id to set id, then use read_part part_name 0 ubi40m part.img to read

8. support write_part fixnv (this is dangerous, make sure just flash own backups, flash nvitem from official pack/other backups LEAD to lost calibration parameters)

9. change savepath by path folder

10. make full backup by read_parts partitions.xml(userdata will be skipped by read_parts), restore backup by write_parts folder (don't try write_parts .)

11. (win only)support device detect (speedup connection speed, and auto exit when device disconnected)

12. r partname/w partname file/e partname

    r only support emmc/ufs, not support nand(except ubipac), r will also calculate part size automatically

13. r/w/e/read_part/write_part support detect slot_a/_b (not include read_parts/write_parts)

14. android 10(+): enable dm-verity by verity 1, disable dm-verity by verity 0
