Cervantes 3 model detection is incorrect about koreader-base HOT 2 CLOSED

Ooh, got it. 0x4040462e is also MXCFB_SEND_UPDATE_OLD for the old Cervantes devices. In ffi/framebuffer_mxcfb.lua we check if the self.device.model is a Cervantes3, but it's actually a Cervantes 3! I'll open a PR :).

@frio: thanks for your feedback!. It is really nice seeing others using KOReader on these devices.

I copied this from original device kernel sources but seems unused, so I will remove that and use MXCFB_SEND_UPDATE for all the lineup, just like qt driver does.

check if the self.device.model is a Cervantes3

The check logic is flawed. There is a tiny little room for optimization in newer devices (ie: using REGAL waveforms in partial/ui updates & set the flags accordly). I got good results in my cervantes4 which I think will work on cervantes3, so If you're willing to try, I will push those changes and leave cervantes2013 as an old device until somebody comes in with that device to test.

BTW, regarding your original comment about the switching page bug on developers firmware, this was fixed upstream in bq/cervantes#9 thanks to @avsej
