rpi: add support for Raspberry Pi 2 model B
USB doesn't seem to work yet; the controller detects the on-board Hub/ Ethernet device but can't read the descriptors from it. I haven't investigated yet. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

/*

* Memory layout for where various images get loaded by boot scripts:
|
||||
*
|
||||
* scriptaddr can be pretty much anywhere that doesn't conflict with something
|
||||
* else. Put it low in memory to avoid conflicts.
|
||||
*
|
||||
* pxefile_addr_r can be pretty much anywhere that doesn't conflict with
|
||||
* something else. Put it low in memory to avoid conflicts.
|
||||
*
|
||||
* kernel_addr_r must be within the first 128M of RAM in order for the
|
||||
* kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
|
||||
* decompress itself to 0x8000 after the start of RAM, kernel_addr_r
|
||||
* should not overlap that area, or the kernel will have to copy itself
|
||||
* somewhere else before decompression. Similarly, the address of any other
|
||||
* data passed to the kernel shouldn't overlap the start of RAM. Pushing
|
||||
* this up to 16M allows for a sizable kernel to be decompressed below the
|
||||
* compressed load address.
|
||||
*
|
||||
* fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
|
||||
* the compressed kernel to be up to 16M too.
|
||||
*
|
||||
* ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
|
||||
* for the FDT/DTB to be up to 1M, which is hopefully plenty.
