* ARM: prevent misaligned array initsAlbert ARIBAUD2012-10-15-0/+3
| | | | | | | | | | | | | | Under option -munaligned-access, gcc can perform local char or 16-bit array initializations using misaligned native accesses which will throw a data abort exception. Fix files where these array initializations were unneeded, and for files known to contain such initializations, enforce gcc option -mno-unaligned-access.

* OMAP: networking support for SPLIlya Yanok2012-10-01-2/+9
| | | | | | | | | | | | | | This patch adds support for networking in SPL. Some devices are capable of loading SPL via network so it makes sense to load the main U-Boot binary via network too. This patch tries to use existing network code as much as possible. Unfortunately, it depends on environment which in turn depends on other code so SPL size is increased significantly. No effort was done to decouple network code and environment so far.

* lib: zlib: remove the limitation for cannot using 0 as startLei Wen2012-09-29-3/+1
| | | | | | | | | | We often need the requirement that compressing those memory range start from 0, but the default deflate code in zlib prevent us to do this. Considering the special case of uboot, that it could access all memory range, it is reasonable to be able to also take the address space from 0 into compression.

* tegra: Add tegra keyboard driverRakesh Iyer2012-05-15-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Add support for internal matrix keyboard controller for Nvidia Tegra platforms. This driver uses the fdt decode function to obtain its key codes. Support for the Ctrl modifier is provided. The left and right ctrl keys are dealt with in the same way. This uses the new keyboard input library (drivers/input/input.c) to decode keys and handle most of the common input logic. The new key matrix library is also used to decode (row, column) key positions into key codes. The intent is to make this driver purely about dealing with the hardware. Key detection before the driver is loaded is supported. This key will be picked up when the keyboard driver is initialized.

* | fdt: Add function to allow aliases to refer to multiple nodesSimon Glass2012-03-29-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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. ] Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* | fdt: Add functions to access phandles, arrays and boolsSimon Glass2012-03-29-0/+67
| | | | | | | | | | | | | | | | | | | | | | | | Add a function to look up a property which is a phandle in a node, and another to read a fixed-length integer array from an fdt property. Also add a function to read boolean properties, although there is no actual boolean type in U-Boot.

* | fdt: Tidy up a few fdtdec problemsSimon Glass2012-03-29-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes five trivial issues in fdtdec.c: 1. fdtdec_get_is_enabled() doesn't really need a default value 2. The fdt must be word-aligned, since otherwise it will fail on ARM 3. The compat_names[] array is missing its first element. This is needed only because the first fdt_compat_id is defined to be invalid. 4. Added a header prototype for fdtdec_next_compatible() 5. Change fdtdec_next_alias() to only increment its 'upto' parameter on success, to make the display error messages in the caller easier.

* | fdt: Add tests for fdtdecSimon Glass2012-03-29-0/+227
| | | | | | | | | | | | | | | | | | | | | | | | The fdtdec_find_aliases_for_id() function is complicated enough that it really should have some tests. This does not necessarily need to be committed to U-Boot, but it might be useful. (note there are a few minor inconsistencies with this patch which will be cleaned up when the USB series is applied) Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* | fdt: Add fdtdec_find_aliases() to deal with alias nodesSimon Glass2012-03-29-0/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stephen Warren pointed out that we should use nodes whether or not they have an alias in the /aliases section. The aliases section specifies the order so far as it can, but is not essential. Operating without alisses is useful when the enumerated order of nodes does not matter (admittedly rare in U-Boot). This is considerably more complex, and it is important to keep this complexity out of driver code. This patch creates a function fdtdec_find_aliases() which returns an ordered list of node offsets for a particular compatible ID, taking account of alias nodes.

* | SPL: Add YMODEM over UART load supportMatt Porter2012-03-26-0/+3
|/ | | | | | | | | | Adds support for loading U-Boot from UART using YMODEM protocol. If YMODEM support is enabled in SPL and the romcode indicates that SPL loaded via UART then SPL will wait for start of a YMODEM transfer via the console port.

* bootstage: Define an optional microsecond timerSimon Glass2012-03-18-0/+17
| | | | | | | | | | | | Define timer_get_boot_us() which returns the number of microseconds since boot. If undefined then we use get_timer() * 1000. We can fit this in a 32-bit register which keeps everyone happy on the efficiency side. It will wrap around after about an hour. If we are still looking at it after an hour then we had better not be timing the boot. Signed-off-by: Simon Glass <sjg@chromium.org>
