Update of scfw to 1.6.0 on imx8qm broke the phy clk

[olivergraute]

Hello,

I updated the scfw binary blob from old 1.2.5 to 1.6.0. Now the U-Boot can't find the phy clock anymore. Is there anything to consider? are there related phy/clk changes inbetween these two versions? (I checked the release note but there are only changes between the version one before 1.6.0)   

I'am using newest mainline U-Boot and not the NXP variant. But with 1.2.5 this setup worked quiet well.

U-Boot 2020.10-00039-gfc8cfe04a2 (Nov 19 2020 - 09:18:54 +0100)

This Issue is caused by the API changes 1.5.1. On my side the patch helped to get mainline U-Boot work again with scfw.

Unfortunately the version of the SCFW it is related to a version of BSP,  L5.4.47_2.2.0_SCFWKIT-1.6.0 it is the version that you need to use with  SCFW 1.6

I apologize for the inconvenience.
