Detail: * Compute module support consists of eMMC support in the SDHCI driver. The eMMC chip on the Compute module only works reliably if under-clocked to 25 MHz. * Pi 1 vs Pi 2 differences are selected at runtime by checking the CPU ID, so a single ROM image will work with both boards. * Added ARMv7 cache maintenance routine for use on Pi 2. * The physical address of the peripherals has moved in Pi 2 to make space for the 1 GB of RAM. * The ARM physical address space is mapped differently onto the GPU address space in Pi 2 because the ARM now uses the L2 cache that comes with the Cortex-A7 instead of the GPU's L2 cache. * Still waiting for confirmation on the board revision ID that will be used for Pi 2, so may require further tweaks for production releases. Version 0.40. Tagged as 'BCM2835-0_40'
