BDK will allow developers to use the full collection of drivers,
with limited editing, if any, for making payloads for Nintendo Switch.
Using a single source for everything will also help decoupling
Switch specific code and easily port it to other Tegra X1/X1+ platforms.
And maybe even to lower targets.
Everything is now centrilized into bdk folder.
Every module or project can utilize it by simply including it.
This is just the start and it will continue to improve.
hekate main always runs in compatibility mode (SDR82).
This ensures speed on boot process.
Nyx will first try SDR104.
If the sd card is a sandisk U1 and fails, it will try the compatibility mode.
After that it fallbacks to lower bus speeds.
Both support 1bit mode for broken sd card readers.
Having the new error checking in the sdmmc driver, allows for all that to work.
It can now fail instead of continuing, like how HOS reacts.
Some Sandisk U1 sd cards do not behave nicely if they power cycle too fast. A min 100ms wait, is enough to mitigate that.
Fortunately, because of how the code paths are structured, this was never hit.
