util/intelp2m: Update output information format in the comments
Update the information format in the comments above the macros in the
generated gpio.h file:
PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE,
DISPUPD), /* LPSS_UART0_TXD */ -->(i)
/* GPIO_39 - LPSS_UART0_TXD */ --> (ii)
/* DW0: 0x44000400, DW1: 0x00003100 */ --> (ii)
/* DW0 : PAD_TRIG(OFF) - IGNORED */ --> (iii)
/* _PAD_CFG_STRUCT(GPIO_39, PAD_FUNC(NF1) | PAD_RESET(DEEP) |
PAD_TRIG(OFF), PAD_PULL(UP_20K) | PAD_IOSTERM(DISPUPD)), */ --> (iiii)
PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE,
DISPUPD),
Also, in the case of field macros:
/* GPIO_39 - LPSS_UART0_TXD */ --> (ii)
/* DW0: 0x44000400, DW1: 0x00003100 */ --> (ii)
/* DW0 : PAD_TRIG(OFF) - IGNORED */ --> (iii)
/* PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE,
DISPUPD), */ --> (iiii)
PAD_CFG_STRUCT(GPIO_39, PAD_FUNC(NF1) | PAD_RESET(DEEP) | PAD_TRIG(OFF),
PAD_PULL(UP_20K) | PAD_IOSTERM(DISPUPD)),
By default, if do not use the -i... option, then additional information
in comments will not be generated.
TEST:
git clone https://github.com/maxpoliak/inteltool-examples.git test
./intelp2m -n -file test/inteltool-asrock-h110m-stx.log
./intelp2m -fld cb -file test/inteltool-asrock-h110m-stx.log
./intelp2m -fld fsp -file test/inteltool-asrock-h110m-stx.log
./intelp2m -fld raw -file test/inteltool-asrock-h110m-stx.log
Before and after (now with -i key) the patch, gpio.h is no different.
