EMMC Initialisation

[Shonk]

For reference i am checking emmc + sd card initialisation by various firmwares
and will post here now and then

you can check this yourself with dmesg via sshdroid from the play store

it would help if other people do the same whilst stating theyr nand chip and firmware

you need to look through dmesg fully as it does a tuning stage on the nand later in the boot process
which the h96 firmware isnt doing atm on the emmc

the end goal is to find the best firmware and to try and shame the box makers into fixing this
