It's a VBE method which supports A, B and recovery images and permits
updating from SPL onwards. The idea is that you can safely update
without bricking a device.

I'm not sure, actually.

Needed so that VPL can use DDT

I can't remember, sorry.

The MMC needs to be accessed using its sequence number

That should say VPL...but again I'm not quite sure

This allows debugging of the jump from TPL to VPL

VPL doesn't want a separate BSS since SDRAM isn't available that early

Just something I noticed

Another thing I noticed

TPL needs to read VPL from MMC

These all help with debugging reading of VPL from the correct MMC device

We don't want this driver in TPL or VPL

Basically there are a lot of little tweaks needed.
