Thanks, works fine on r8a7791/koelsch!

Interestingly, the ECSR_MPD bit is already set for several SoCs.
Hence adding ".magic = 1" to the entry for r8a7740 instantly gave me working
WoL support on r8a7740/armadillo. Cool!

Instead of adding a new flag, perhaps you can just check for the ECSR_MPD flag
in ecsr_value?

"unsigned wol_enabled:1", to merge with the bitfield above?

It's a good practice to keep all pointers at the top of the struct, to avoid
gaps due to alignment restrictions, especially on 64-bit (I know that's not
the case here).
