This adds clock references to the USB part of the device tree for U-Boot,
and marks USB1 as supporting legacy mode (which we disable in the driver).

The USB timing information may vary between boards sometimes, but for
now we hard-code it in C. This is because all current T2x boards use
the same values, we will deal with T3x later and we first need to agree

12 years agofdt: Add basic support for decoding GPIO definitions
Simon Glass [Mon, 27 Feb 2012 10:52:36 +0000 (10:52 +0000)]
fdt: Add basic support for decoding GPIO definitions

This adds some support into fdtdec for reading GPIO definitions from
the fdt. We permit up to FDT_GPIO_MAX GPIOs in the system. Each GPIO
is of the form:

gpio-function-name = <phandle gpio_num flags>;

where:

phandle is a pointer to the GPIO node
gpio_num is the number of the GPIO (0 to 223)
flags is a flag, as follows:

   bit    meaning
   0      0=polarity normal, 1=active low (inverted)

An example is:

enable-propounder-gpios = <&gpio 43 0>;

which means that GPIO 43 is used to enable the propounder (setting the
GPIO high), or that you can detect that the propounder is enabled by
checking if the GPIO is high (the fdt does not indicate input/output).

Two main functions are provided:

fdtdec_decode_gpio() reads a GPIO property from an fdt node and decodes it
into a structure.

fdtdec_setup_gpio() sets up the GPIO by calling gpio_request for you.

Both functions can cope with the property being missing, which is taken to
mean that that GPIO function is not available or is not needed.

[For reference, from Stephen Warren <swarren@nvidia.com>. It may be that
we add this extra complexity later if needed:

The correct way to parse such a GPIO property in general is:

* Read the first cell.
* Find the node referenced by the phandle (the controller).
* Ensure property gpio-controller is present in the controller node.
* Read property #gpio-cells from the controller node.
* Extract #gpio-cells from the original property.
* Keep processing more cells from the original property; there may be
multiple GPIOs listed.

According to the binding documentation in the Linux kernel, Samsung
Exynos4 doesn't use this format, and while all other chips do have a
flags cell, about 50% of the controllers indicate the cell is unused.

At the moment, both the IPU and VPU libraries provided by Freescale
in the "imx-lib" package contain routines which scrape the system
revision from /proc/cpuinfo. In the VPU library, this information is
used to load the proper firmware, allowing a single binary to be used
across various i.MX processors.

Dirk Behme [Wed, 22 Feb 2012 22:50:19 +0000 (22:50 +0000)]
imximage: Remove overwriting of flash_offset

The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).

The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().

Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.

If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.
