Since memory on 32mb ipod videos is mapped twice, a 64mb build still has codecs and plugins mapped in a usable area. This means that all that needs to be done to support 32mb and 64mb boards with the same build is to adjust audiobufend to avoid using more than the actually present RAM.

This adds proper full speed charging support for iPod 4G, Color, Mini 1G, Mini 2G, Nano 1G, and Video. Nano 2G already has support, so now all ipods charge (except 1G-3G whose hardware doesn't support USB charging).
USB charging defaults to on, but will only charge at full speed from a USB host. To charge from an AC charger, you need to set the USB charging mode to "force". It may be possible to detect AC chargers in a future version, at least on some models.

The cost of LBA48 support is very small and it means that upgraded drives/CF cards which are over 128GiB will just work with no custom build required. There should be no runtime effect on disks which do not require it.

DMA is only used for reading because writing seems to be slower with DMA.
Only requests which are cacheline aligned (16 bytes) will use DMA, so many
requests will still use PIO at this point; a later change will align more
reads.
Part of FS#9708, original DMA code by Boris Gjenero (dreamlayers).
