* dm: exynos: Convert SPI to driver modelSimon Glass2014-10-22-336/+190
| | | | | | | | | | Move the exynos SPI driver over to driver model. This removes quite a bit of boilerplate from the driver, although it adds some for driver model. A few device tree additions are needed to make the SPI flash available. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>

* dm: spi: Remove SPI_INIT featureSimon Glass2014-10-22-8/+0
| | | | | | | | | | | | This feature provides for init of a single SPI port for the soft SPI feature. It is not really compatible with driver model since it assumes a single SPI port. Also, inserting SPI init into the driver by means of a #define is not very nice. This feature is not used by any active boards, so let's remove it.

* dm: sandbox: Add a SPI emulation uclassSimon Glass2014-10-22-0/+62
| | | | | | | | | | | | | | | | | U-Boot includes a SPI emulation driver already but it is not explicit, and is hidden in the SPI flash code. Conceptually with sandbox's SPI implementation we have a layer which creates SPI bus transitions and a layer which interprets them, currently only for SPI flash. The latter is actually an emulation, and it should be possible to add more than one emulation - not just SPI flash. Add a SPI emulation uclass so that other emulations can be plugged in to support different types of emulated devices on difference buses/chip selects.

| | | | | | | | | | | | | | | | Add a uclass which provides access to SPI buses and includes operations required by SPI. For a time driver model will need to co-exist with the legacy SPI interface so some parts of the header file are changed depending on which is in use. The exports are adjusted also since some functions are not available with driver model. Boards must define CONFIG_DM_SPI to use driver model for SPI.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

SEC block protects data in a data structure called a Blob, which provides both confidentiality and integrity protection. Encapsulating data as a blob Each time that the Blob Protocol is used to protect data, a different randomly generated key is used to encrypt the data. This random key is itself encrypted using a key which is derived from SoC's non volatile secret key and a 16 bit Key identifier. The resulting encrypted key along with encrypted data is called a blob. The non volatile secure key is available for use only during secure boot. During decapsulation, the reverse process is performed to get back the original data. Commands added -------------- blob enc - encapsulating data as a cryptgraphic blob blob dec - decapsulating cryptgraphic blob to get the data Commands Syntax --------------- blob enc src dst len km Encapsulate and create blob of data $len bytes long at address $src and store the result at address $dst. $km is the 16 byte key modifier is also required for generation/use as key for cryptographic operation.
