Intel Pad to Macro (intelp2m) converter Intel Pad to Macro (intelp2m) converter
======================================= =======================================
This utility allows to convert the configuration DW0/1 registers value This utility allows one to convert the configuration DW0/1 register
from [inteltool](../inteltool/description.md) dump to coreboot macros. values from an inteltool dump to coreboot macros.

It is possible to use templates for parsing files of excellent inteltool.log. It is possible to use templates for parsing inteltool.log files.
To specify such a pattern, use the option -t <template number>. For example, To specify such a pattern, use the option `-t <template number>`.
using template type # 1, you can parse gpio.h from an already added board in
the coreboot project. ```text
```bash
(shell)$ ./intelp2m -h
-t -t
template type number template type number
0 - inteltool.log (default) 0 - inteltool.log (default)
1 - gpio.h 1 - gpio.h
2 - your template 2 - your template
(shell)$ ./intelp2m -t 1 -file coreboot/src/mainboard/yourboard/gpio.h
``` ```
You can also add a template to 'parser/template.go' for your file type with
the configuration of the pads. For example, using template type 1, you can parse gpio.h from an
existing board in the coreboot project.
```bash
./intelp2m -t 1 -file coreboot/src/mainboard/yourboard/gpio.h
```
You can also add a template to 'parser/template.go' for your file type
with the configuration of the pads.
