* ARM: bcm2835: add simplefb DT node during bootz/mStephen Warren2013-06-05-1/+13
| | | | | | | | | | Add a DT simple-framebuffer node to DT when booting the Linux kernel. This will allow the kernel to inherit the framebuffer configuration from U-Boot, and display a graphical boot console, and even run a full SW- rendered X server.

* ARM: rpi_b: enable SD controller, add related env/cmdsStephen Warren2013-03-20-0/+26
| | | | | | | | | | | Enable the SD controller driver for the Raspberry Pi. Enable a number of useful MMC, partition, and filesystem-related commands. Set up the environment to provide standard locations for loading a kernel, DTB, etc. Provide a boot command that loads and executes boot.scr.uimg from the SD card; this is written considering future extensibilty to USB storage.

* ARM: rpi_b: use bcm2835 mbox driver to get memory sizeStephen Warren2013-03-20-1/+20
| | | | | | | | | | | The firmware running on the bcm2835 SoC's VideoCore CPU determines how much of the system RAM is available for use by the ARM CPU. Previously, U-Boot assumed that only 128MB was available, since this was the smallest value configured by any public firmware. However, we can now query the actual value at run-time from the firmware using the mbox property protocol. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* ARM: add Raspberry Pi model B board, using BCM2835 SoCStephen Warren2012-09-01-0/+68
The Raspberry Pi model B uses the BCM2835 SoC, has 256MB of RAM, contains an SMSC 9512 USB LAN/Hub chip, and various IO connectors. For more details, see http://www.raspberrypi.org/. Various portions (cache enable, MACH_TYPE setup, RAM size limit, stack relocation to top of RAM) extracted from work by: Oleksandr Tymoshenko <gonzo@bluezbox.com>. GPIO driver enablement by Vikram Narayanan <vikram186@gmail.com>. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Tom Rini <trini@ti.com>
