net/designware: Try configuring phy on each dw_eth_init

Phy autonegotiation works only when the ethernet cable is plugged in.
Since the phy was configured only at the init time, a plugged in cable
was necessary to initialize the phy properly.

This patch keeps a flag to check if the phy initialization has
succeeded, and calls configure_phy routine at every init if this flag
reports otherwise.

12 years agonet/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall back
Eric Miao [Wed, 18 Jan 2012 22:56:33 +0000 (22:56 +0000)]
net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall back

Ignore the return value of eth_getenv_enetaddr_by_index(), and if it
fails, fall back to use dev->enetaddr, which could be filled up by
the ethernet device driver:

With the current code, introduced with below commit, eth_write_hwaddr()
will fail immediately if there is no eth<n>addr in the environment variables.

However, e.g. for an overo based product that uses the SMSC911x ethernet
chip (with the MAC address set via EEPROM connected to the SMSC911x chip),
the MAC address is still OK.

On mx28 boards that are depending on the OCOTP bits to set the MAC address
(like the Denx m28 board), the OCOTP bits should be used instead of
failing on the environment variables.

Actually, this was the original behavior, and was later changed by
commit 7616e7850804c7c69e0a22c179dfcba9e8f3f587.

arm: Use common .lds file where possible

Each cpu directory currently has its own .lds file. This is only needed
in most cases because the start.o file is in a different subdir.

Now that we can factor out this difference, we can move most cpus over
to the common .lds file.

12 years agoarm: add a common .lds link script
Simon Glass [Thu, 23 Feb 2012 03:28:41 +0000 (03:28 +0000)]
arm: add a common .lds link script

Most ARM CPUs use a very similar link script. This adds a basic
script that can be used by most CPUs.

Two new symbols are introduced which are intended to eventually be
defined on all architectures to make things easier for generic relocation
and reduce special-case code for each architecture:

__image_copy_start is the start of the text area (equivalent to the
existing _start on ARM). It marks the start of the region which must be
copied to a new location during relocation. This symbol is called
__text_start on x86 and microblaze.

__image_copy_end is the end of the region which must be copied to a new
location during relocation. It is normally equal to the start of the BSS
region, but this can vary in some cases (SPL?). Making this an explicit
symbol on its own removes any ambiguity and permits common code to always
do the right thing.

This new script makes use of CPUDIR, now defined by both Makefile and
spl/Makefile, to find the directory containing the start.o object file,
which is always placed first in the image.

To permit MMU setup prior to relocation (as used by pxa) we add an area
to the link script which contains space for this. This is taken
from commit 7f4cfcf. CPUs can put the contents in there using their
start.S file. BTW, shouldn't that area be 16KB-aligned?

This is set by the top level Makefile anyway, so drop it. This does

fdt: Add function to allow aliases to refer to multiple nodes

Some devices can deal with multiple compatible properties. The devices
need to know which nodes to bind to which features. For example an
I2C driver which supports two different controller types will want to
know which type it is dealing with in each case.

The new fdtdec_add_aliases_for_id() function deals with this by allowing
the driver to search for additional compatible nodes for a different ID.
It can then detect the new ones and perform appropriate processing.

Another option considered was to return a tuple (node offset, compat id)
and have the function be passed a list of compatible IDs. This is more
overhead for the common case though. We may add such a function later if
more drivers in U-Boot require it.

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.

atmel-boards: add missing atmel_mci.h

commit 72fa467988e7944407a634ddc4bc6a2df685c04c moved atmel_mci_init() into
include/atmel_mci.h. Some AT91 boards are also using this interface and need
to include atmel_mci.h now.

This patch fixes MAKEALL complaints like this:
