2013-06-05ARM: bcm2835: add simplefb DT node during bootz/mStephen Warren
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.

2013-04-04ARM: bcm2835: fix get_timer() to return msStephen Warren
Apparently, CONFIG_SYS_HZ must be 1000. Change this, and fix the timer driver to conform to this. Have the timer implementation export a custom API get_timer_us() for use by the BCM2835 MMC API, which needs us resolution for a HW workaround. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
2013-03-20ARM: rpi_b: enable SD controller, add related env/cmdsStephen Warren
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.

2013-03-20video: add a driver for the bcm2835Stephen Warren
The firmware running on the bcm2835 SoC's VideoCore CPU manages the display controller. Add a simple "LCD" driver that communicates with the firmware using the property mailbox protocol. This configures the display and frame-buffer to match whatever physical resolution the firmware chosen when booting, which is typically the native resolution of the attached display device, presumably unless otherwise specified in config.txt on the boot media. Enable this driver in the Raspberry Pi board configuration. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2013-03-20ARM: rpi_b: disable rpi_b dcache explicitlyStephen Warren
There appears to be no implementation of flush_dcache_range() for ARM1176, so explicitly disable dcache support to avoid references to that function from the LCD core in the next patch. This was presumably not noticed before simply because no drivers for the rpi_b were attempting DMA. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
2012-09-01ARM: add Raspberry Pi model B board, using BCM2835 SoCStephen Warren
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>.
