Hi Rasmus,
Kernel 5.6-rc1 silently fails on boot.
I bisected the problem to commit b6231ea2b3c6 ("soc: fsl: qe: drop broken lazy call of cpm_muram_init()")
I get a bad_page_fault() for an access at address 8 in cpm_muram_alloc_common(), called from cpm_uart_console_setup() via cpm_uart_allocbuf()
Reverting the guilty commit on top of 5.6-rc1 is not trivial.
In your commit text you explain that cpm_muram_init() is called via subsys_initcall. But console init is done before that, so it cannot work.
Do you have a fix for that ?
Thanks Christophe
NB: Next time, can you please copy powerpc mailing list when changing such core parts of powerpc CPUs ?
