Hi Christophe,

The Cyrus+ board with FSL P50x0 SoC [1] doesn't boot with the PowerPC 
updates 5.16-1 [2].

I was able to revert the new PowerPC updates 5.16-1 [2]. After a new 
compiling, the kernel boots without any problems on the Cyrus+ board.

I bisected today [3]. 52bda69ae8b5102fe08c9db10f4a1514478e07d3 
(powerpc/fsl_booke: Tell map_mem_in_cams() if init is done) [4] is the 
first bad commit.

I was able to revert the first bad commit [3]. I had to revert the 
commit d5970045cf9e266d9a43941ac0866865fd22a36a additionally because of 
a compiling error. After a new compiling, the kernel boots without any 
problems.

I created a patch for an easy reverting the bad commit (including the 
other dependent commit) [3]. With this patch we can do further our 
kernel tests.

Could you please check the first bad commit [4]?

Please find attached the kernel config.

Thanks,
Christian
