0b304a2494 sandbox: dts: Add a SPI device and cros_ec device
Add a SPI device which can be used for testing SPI flash features in
sandbox.

Also add a cros_ec device since with driver model the Chrome OS EC
emulation will not otherwise be available.

The pinctrl bindings used by Linux are an incomplete description of the

fix this, and avoid adding a table to U-Boot for every single Exynos

f887cb6d86 dm: add of_match_ptr() macro
The driver model supports two ways for passing device parameters;
Device Tree and platform_data (board file).
Each driver should generally support both of them because some
popular IPs are used on various platforms.

Assume the following scenario:
  - The driver Foo is used on SoC Bar and SoC Baz
  - The SoC Bar uses Device Tree control (CONFIG_OF_CONTROL=y)
  - The SoC Baz does not support Device Tree; uses a board file

In this situation, the device driver Foo should work with/without
the device tree control.  The driver should have .of_match and
.ofdata_to_platdata members for SoC Bar, while they are meaningless
for SoC Baz; therefore those device-tree control code should go
inside #ifdef CONFIG_OF_CONTROL.

The driver code will be like this:

  #ifdef CONFIG_OF_CONTROL
  static const struct udevice_id foo_of_match = {
          { .compatible = "foo_driver" },
          {},
  }

  static int foo_ofdata_to_platdata(struct udevice *dev)
  {
          ...
  }
  #endif

  U_BOOT_DRIVER(foo_driver) = {
          ...
          .of_match = of_match_ptr(foo_of_match),
          .ofdata_to_platdata = of_match_ptr(foo_ofdata_to_platdata),
          ...
  }

This idea has been borrowed from Linux.
(In Linux, this macro is defined in include/linux/of.h)

29a1bedbf3 dm: do not check the existence of uclass operation
The function uclass_add() checks uc_drv->ops as follows:

        if (uc_drv->ops) {
                dm_warn("No ops for uclass id %d\n", id);
                return -EINVAL;
        }

It seems odd because it warns "No ops" when uc_drv->ops has
non-NULL pointer.  (Looks opposite.)

Anyway, most of UCLASS_DRIVER entries have no .ops member.
This check makes no sense.

aeb3fcb359
ARM: tegra: Use mem size from MC rather than ODMDATA

In addition to the move of using the Tegra memory controller (MC)
register rather than ODMDATA for T20, T30 and T114 as well it further
uses the generic get_ram_size() function (see "common/memsize.c")
<supposed to be used in each and every U-Boot port>TM. Added benefit is
that it should <catch 99% of hardware related (i. e. reliably
reproducible) memory errors> as well.

Thoroughly tested on the various Toradex line of Tegra modules
available which unfortunately does not include T114 and T124 (yet at
least) plus on the Jetson TK1.

09fb73611f mmc: Tegra: Fix timeout issue seen on certain eMMC parts
During rigorous testing of our latest update infrastructure I came
across quite consistent timeouts on certain eMMC parts (e.g. Hynix
H26M21001ECR) when writing big (e.g. in excess of 400 MB) file system
images:

MMC write: dev # 0, block # 40960, count 944128 ...
 mmc_send_cmd_bounced: MMC Timeout
    Interrupt status        0x00000001
    Interrupt status enable 0xdfff003b
    Interrupt signal enable 0xdfff0002
    Present status          0x01870106
mmc write failed

Comparing the various data sheets I came across the following timeout
specification:

Secure Erase/TRIM Timeout=300ms*2*10=6000ms

Unfortunately empirical testing still failed albeit much more rarely.
Increasing the timeout to 8000ms made it finally disappear entirely.
This patch allows us writing various eMMC parts without seeing any
further issues.

bf78b2717d arm: tegra: initial support for apalis t30
This patch adds board support for the Toradex Apalis T30 a computer on
module which can be used on different carrier boards.

For the sake of ease of use we do not distinguish between different
carrier boards for now as the base module features are deemed
sufficient enough for regular booting.

The following functionality is working so far:
- eMMC boot and environment storage
- Gigabit Ethernet (once Thierry's PCIe as well as my E1000 resp. i210
  fixes hit mainline)
- MMC/SD cards (both 8-bit as well as 4-bit slot)
- USB client/host (dual role port as client e.g. for DFU/UMS, other two
  ports as host)
