• f66f2aa26   ARM: rpi_b: power on SDHCI and USB HW modules ... Browse Code »

  Send RPC commands to the VideoCore to turn on the SDHCI and USB modules.
  For SDHCI this isn't needed in practice, since the firmware already
  turned on the power in order to load U-Boot. However, it's best to be
  explicit. For USB, this is necessary, since the module isn't powered
  otherwise. This will allow the kernel USB driver to work.

• ea697ae7e   ARM: bcm2835: add simplefb DT node during bootz/m ... Browse Code »

  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.

• 131a1e603   ARM: rpi_b: enable SD controller, add related env/cmds ... Browse Code »

  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.

• 3f397782a   ARM: rpi_b: use bcm2835 mbox driver to get memory size ... Browse Code »

  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.
