    bcm4908: add testing support for kernel 5.10
    
    CONFIG_COMPAT_32BIT_TIME is a new symbol and has to be set to avoid:
    Provide system calls for 32-bit time_t (COMPAT_32BIT_TIME) [N/y/?] (NEW)
    
    CONFIG_RELOCATABLE needs to be enabled to make kernel start booting.
    That raises a question: do we really need CONFIG_EXPERT=y ?
