About u-boot CONFIG_U_QE and CONFIG_QE config options

[harnoisanne-sop]

Hello, what does the u-boot config CONFIG_U_QE mean? I suppose CONFIG_QE is for Quick engine? but no idea about CONFIG_U_QE. Is there some documentation about these options? I didn't find it.

Many thanks

The T1042 QE block is the same as the T1040/ T1020/T1022 LS1021A/LS10 20A QE block. See the QUICC Engine Block Reference Manual:

https://www.nxp.com/webapp/Download?colCode=QEIWRM&location=null&fpsp=1&WT_TYPE=Reference%20Manuals&...

The LS1021A Reference Manual names this QE block as "QUICC Engine (QE) lite block".

The u-boot uses CONFIG_U_QE and CONFIG_QE definitions for configuring of this block.

Have a great day,
