| * ARM: rpi_b: enable USB/DHCP/PXE in bootcmdStephen Warren2014-10-22-11/+14
| | | | | | | | | | | | | | USB support must be enabled before config_distro_bootcmd.h is included for bootcmd to include USB-related functionality. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
| * ARM: rpi_b: query internal MAC address from firmwareStephen Warren2014-10-22-0/+1
| | | | | | | | | | | | | | | | The built-in SMSC 95xx chip doesn't know its own MAC address. Instead, we must query it from the VC firmware; it's probably encoded in fuses on the BCM2835. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

* | dm: rpi: Convert GPIO driver to driver modelSimon Glass2014-10-22-0/+5
|/ | | | | | | | | Convert the BCM2835 GPIO driver to use driver model, and switch over Raspberry Pi to use this, since it is the only board. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Stephen Warren <swarren@wwwdotorg.org>
* ARM: rpi_b: use new generic $bootcmdStephen Warren2014-08-09-93/+36
| | | | | | | | | | | | | | | Replace the custom $bootcmd with that from <config_distro_bootcmd.h>. There should be no functional change, since the new generic $bootcmd was derived strongly from tegra-common-post.h, after which this part of rpi_b.h was modelled. The #defines to enable/disable U-Boot commands/features were moved earlier in rpi_b.h, so they are set up before config_distro_bootcmd.h is included, since it tests whether certain features should be included based on those defines.

* ARM: rpi_b: rework boot scripts, enable sysbootStephen Warren2014-02-22-15/+70
| | | | | | | | | | | | | | | Rework rpi_b's bootcmd (and sub-commands) to match Tegra's bootcmd as much as possible. This will aid in a future patch which will create a common header e.g. config_distro_bootcmd.h. While at it, enable booting from extlinux.conf using the sysboot command. The iteration and componentization currently makes a little more sense for Tegra than RPi, but I'd still like to keep the two as similar as possible. USB and networking support is coming to the RPi in due course, and it'll all make more sense then anyway. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* ARM: rpi_b: load /uEnv.txt from MMC at startupStephen Warren2014-02-21-0/+5
| | | | | | | | | | | The Pi has no flash to store an environment in the usual fashion. However, the user may wish to customize the environment. We know that the SD card must be present, since that's where the boot ROM has loaded U-Boot from. So, load uEnv.txt from there early during boot. This allows the user to e.g. customize boot_targets, in order to automatically select network boot. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* ARM: rpi_b: convert to use distro defaultsStephen Warren2014-02-21-16/+13
| | | | | | | | Modify the rpi_b board to include the "distro defaults" header, so that all the config options distros expect are enabled. Remove any #defines that enable the same options from the rpi_b.h. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* ARM: rpi_b: set $fdtfile in default environmentStephen Warren2014-02-13-0/+1
| | | | | | | | | | | | | | U-Boot names the Raspberry Pi board rpi_b. This means that the common expression for DTB filename ${soc}-${board}.dtb expands to bcm2835-rpi_b.dtb. However, the DTB generated by the Linux kernel is bcm2835-rpi-b.dtb. Set $fdtfile in U-Boot's environment so that scripts look for the correct DTB filename. An alternative would be to rename the U-Boot board to rpi-b. However, that change would be far more invasive, and end up affecting users (i.e they'd have to change their U-Boot build commands).

* config: remove platform CONFIG_SYS_HZ definition part 2/2Rob Herring2013-11-04-3/+0
| | | | | | Remove platform CONFIG_SYS_HZ definition for configs a-z*. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
* ARM: bcm2835: add simplefb DT node during bootz/mStephen Warren2013-06-05-0/+2
| | | | | | | | | | 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: bcm2835: fix get_timer() to return msStephen Warren2013-04-04-1/+1
| | | | | | | | | | 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>
* ARM: rpi_b: enable SD controller, add related env/cmdsStephen Warren2013-03-20-3/+65
| | | | | | | | | | | 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.

* video: add a driver for the bcm2835Stephen Warren2013-03-20-0/+16
| | | | | | | | | | | | | | | 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>
* ARM: rpi_b: disable rpi_b dcache explicitlyStephen Warren2013-03-20-0/+1
| | | | | | | | | | 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>
* ARM: add Raspberry Pi model B board, using BCM2835 SoCStephen Warren2012-09-01-0/+104
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>.
