| * video: add VPL ioctl to get bus formatPhilipp Zabel2016-08-251-0/+1
| | | | | | | | | | | | | | | | | | The i.MX specific DI_MODE VPL ioctl already allows to query the encoder input bus format. This patch also allows non-i.MX specific encoder drivers to report their input bus format. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * video: switch to media bus formatsPhilipp Zabel2016-08-252-151/+137
| | | | | | | | | | | | | | | | | | | | | | V4L2 pixel formats are supposed to describe video frames in memory. To describe the pixel format on the hardware bus between display interface and encoders, use media bus formats, which are more expressive. This allows to get rid of the custom GBR24 and LVDS666 fourccs. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * nv: Save nv variables on shutdownSascha Hauer2016-07-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch nv variables are automatically saved whenever barebox shuts down (that is 'reset' is executed or a kernel is started). With this the additional 'saveenv' step becomes unnecessary. The nv variables are stored in the environment and the estasblished behaviour is that files in the environment must be manually saved using 'saveenv'. This behaviour shall be kept for now, so this patch cannot just call 'saveenv' since that would save the modified environment files aswell. Instead we read the environment from the device, modifiy the nv variables and save the environment back. Since this changes a long existing behaviour messages are printed the first time a nv variable is modified and during shutdown when the variables are actually saved.

| * | ARM i.MX31: add SPI supportAlexander Kurz2016-08-031-0/+7
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i.MX31 SPI interface was refered by freescale as spi_ver_0_4 in one of their older vendor extended linux releases. spi_ver_0_4 differs only in minor aspects to spi_ver_0_7 (i.MX35) which is already supported by barebox. Regarding barebox, the differences boil down to the location and length of the CHIP SELECT and BIT COUNT/BURST LENGTH elements of CONREG. The spi_ver_0_4 variant is limited to single word bursts with a maximum of 32 bits_per_word. Add support for the i.MX31 SPI interface to the barebox spi_ver_0_7 implementation.

| | | | | | | | | | | | | | | | | | This completes the separation of the blspec code from the boot code.

* | bootentries: Add title/descriptionSascha Hauer2016-07-261-0/+4
| | | | | | | | | | | | | | | | | | | | We currently have to special case blspec entries vs. boot scripts in the common boot code since we want to print different informations about them. This adds a 'title' and 'description' which can be filled in with different information by bootscripts and blspec entries and so we get rid of the special handling.

* | blpec: rename struct lspec -> bootentriesSascha Hauer2016-07-261-19/+19
| | | | | | | | | | | | | | | | | | | | | | The code in common/boot.c collects the different boot entries in lists of type struct blspec, eventhough many of them may not be bootloader spec entries but for example boot scripts. This is the first step of separating the data structures from boot entries and bootloader spec: As struct blspec is merely a container for collecting boot entries We simply rename struct blspec to struct bootentries.

Unfortunately the architecture and abstractions disappeared during this period. This patch refactors the framework to recreate the abstractions. The main focus was the backend with its storage. The main use-case was to offer better NAND support with less erase cycles and interchangeable data formats (dtb,raw). The general architecture now has a backend which consists of a data format and storage. The storage consists of multiple storage buckets each holding exactly one copy of the state data. A data format describes a data serialization for the state framework. This can be either dtb or raw. A storage bucket is a storage location which is used to store any data. There is a (new) circular type which writes changes behind the last written data and therefore reduces the number of erases. The other type is a direct bucket which writes directly to a storage offset for all non-erase storage. Furthermore this patch splits up all classes into different files in a subdirectory. This is currently all in one patch as I can't see a good way to split the changes up without having a non-working state framework in between. The following diagram shows the new architecture roughly: .----------. | state | '----------' | | v .----------------------------. | state_backend | |----------------------------| | + state_load(*state); | | + state_save(*state); | | + state_backend_init(...); | | | | | '----------------------------' | | The format describes | | how the state data | '-------------> is serialized | .--------------------------------------------. | | state_backend_format <INTERFACE> | | |--------------------------------------------| | | + verify(*format, magic, *buf, len); | | | + pack(*format, *state, **buf, len); | | | + unpack(*format, *state, *buf, len); | | | + get_packed_len(*format, *state); | | | + free(*format); | | '--------------------------------------------' | ^ ^ | * * | * * | .--------------------. .--------------------. | | backend_format_dtb | | backend_format_raw | | '--------------------' '--------------------' | | | v .----------------------------------------------------------. | state_backend_storage | |----------------------------------------------------------| | + init(...); | | + free(*storage); | | + read(*storage, *format, magic, **buf, *len, len_hint); | | + write(*storage, *buf, len); | | + restore_consistency(*storage, *buf, len); | '----------------------------------------------------------' | The backend storage is responsible to manage multiple data copies and distribute them onto several buckets.
