* hi_read_r_xcorr.v: avoid overflows during accumulation and truncation
* explicitely cast unsigned ADC samples to signed
any memory from BigBuf[]. This is required because FpgaDownloadAndGo() might
allocate, use, and free most of BigBuf[] when decompressing FPGA configs.
- cleanup: remove rests of deprecated "end of trace markers" (0x44)
CHG: USB_CMD_DATA_SIZE is now used as maxsize for transfer of data between client and pm3device
CHG: suggested a fix for the underscore problem in ioclass\fileutils.c
ADD: tnp3xx support
ADD: nxp tag idents.
ADD: identifiction of chinese backdoor commands to hf 14a reader.
