I asked yesterday about GPU access documentation - if only simple read/write to a framebuffer after 'something' sets up said framebuffer.
Further to this, is the SD card accessed via the GPU or the CPU? The reason for asking is the implication of the GPU having control over the SD card due to the booting mechanism (or have both devices have some form of shared access?).
Is the method SD card access going to be made public (even if it requires bit banged IO)?
