* rsa: Use checksum algorithms from struct hash_algoRuchika Gupta2015-01-29-6/+18
| | | | | | | | | | | | | | | Currently the hash functions used in RSA are called directly from the sha1 and sha256 libraries. Change the RSA checksum library to use the progressive hash API's registered with struct hash_algo. This will allow the checksum library to use the hardware accelerated progressive hash API's once available.

* hash: Add function to find hash_algo struct with progressive hashRuchika Gupta2015-01-29-0/+14
| | | | | | | | | | | | The hash_algo structure has some implementations in which progressive hash API's are not defined. These are basically the hardware based implementations of SHA. An API is added to find the algo which has progressive hash API's defined. This can then be integrated with RSA checksum library which uses Progressive Hash API's.

* rsa: Split the rsa-verify to separate the modular exponentiationRuchika Gupta2015-01-29-0/+43
| | | | | | | | | | | | | | | | | | | | | | Public exponentiation which is required in rsa verify functionality is tightly integrated with verification code in rsa_verify.c. The patch splits the file into twp separating the modular exponentiation. 1. rsa-verify.c - The file parses device tree keys node to fill a keyprop structure. The keyprop structure can then be converted to implementation specific format. (struct rsa_pub_key for sw implementation) - The parsed device tree node is then passed to a generic rsa_mod_exp function. 2. rsa-mod-exp.c Move the software specific functions related to modular exponentiation from rsa-verify.c to this file.

* Export redesignMartin Dorwig2015-01-29-40/+83

The EXPORT_FUNC macro now has 3 fixed parameters and one variadic parameter The first is the name of the exported function, the rest of the parameters are used to format a functionpointer in the jumptable, the EXPORT_FUNC macros are expanded three times, 1. to declare the members of the struct 2. to initialize the structmember pointers 3. to call the functions in stubs.c Signed-off-by: Martin Dorwig <dorwig@tetronik.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org> (resending to the list since my tweaks are not quite trivial)

* dm: i2c: Move slave details to child platdataSimon Glass2015-01-29-2/+2
| | | | | | | | | | | | | | | | | At present we go through various contortions to store the I2C's chip address in its private data. This only exists when the chip is active so must be set up when it is probed. Until the device is probed we don't actually record what address it will appear on. However, now that we can support per-child platform data, we can use that instead. This allows us to set up the address when the child is bound, and avoid the messy contortions. Unfortunately this is a fairly large change and it seems to be difficult to break it down further.

* dm: core: Allow uclass to set up a device's child before it is probedSimon Glass2015-01-29-0/+15
| | | | | | | | | Some buses need to set up their devices before they can be used. This setup may well be common to all buses in a particular uclass.

* dm: core: Allow the uclass to set up a device's child after bindingSimon Glass2015-01-29-0/+2
| | | | | | | | | | | | For buses, after a child is bound, allow the uclass to perform some processing. This can be used to figure out the address of the child (e.g. the chip select for SPI slaves) so that it is ready to be probed. This avoids bus drivers having to repeat the same process, which really should be done by the uclass, since it is common.

* dm: core: Allow uclasses to specify private data for a device's childrenSimon Glass2015-01-29-0/+4
| | | | | | | | | | | | | | In many cases the per-child private data for a device's children is defined by the uclass rather than the individual driver. For example, a SPI bus needs to store information about each of its children, but all SPI drivers store the same information. It makes sense to allow the uclass to define this data. If the driver provides a size value for its per-child private data, then use it. Failng that, fall back to that provided by the uclass.

* dm: core: Add a flag to control sequence numberingSimon Glass2015-01-29-0/+5
| | | | | | | | | | | | | | | | At present we try to use the 'reg' property and device tree aliases to give devices a sequence number. The 'reg' property is often actually a memory address, so the sequence numbers thus-obtained are not useful. It would be better if the devices were just sequentially numbered in that case. In fact neither I2C nor SPI use this feature, so drop it. Some devices need us to look up an alias to number them within the uclass. Add a flag to control this, so it is not done unless it is needed.

| | | | | | | | | | | | | For boards which use multiple I2C devices, or for SOCs which support multiple boards, we might want to convert these to driver model at different times. At present this is difficult because we need to either use CONFIG_DM_I2C for a board or not.

* dm: gpio: Add better functions to request GPIOsSimon Glass2015-01-29-0/+199
| | | | | | | | | | | | | | | | | | | | | | | At present U-Boot sort-of supports the standard way of reading GPIOs from device tree nodes, but the support is incomplete, a bit clunky and only works for GPIO bindings where #gpio-cells is 2. Add new functions to request GPIOs, taking full account of the device tree binding. These permit requesting a GPIO with a simple call like: gpio_request_by_name(dev, "cd-gpios", 0, &desc, GPIOD_IS_IN); This will request the GPIO, looking at the device's node which might be this, for example: cd-gpios = <&gpio TEGRA_GPIO(B, 3) GPIO_ACTIVE_LOW>; The GPIO will be set to input mode in this case and polarity will be honoured by the GPIO calls.

* dm: gpio: Add a native driver model APISimon Glass2015-01-29-0/+16
| | | | | | | | | | | | | | | | | | | | | | | So far driver model's GPIO uclass just implements the existing GPIO API. This has some limitations: - it requires manual device tree munging to support GPIOs in device tree (fdtdec_get_gpio() and friends) - it does not understand polarity - it is somewhat slower since we must scan for the GPIO device each time - Global GPIO numbering can change if other GPIO drivers are probed - it requires extra steps to set the GPIO direction and value The new functions have a dm_ prefix where necessary to avoid name conflicts but we can remove that when it is no-longer needed. The new struct gpio_desc holds all required information about the GPIO. For now this is intended to be stored by the client requesting the GPIO, but in future it might be brought into the uclass in some way. With these changes the old GPIO API still works, and uses the driver model API underneath. Signed-off-by: Simon Glass <sjg@chromium.org>
