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.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Non volatile device variables are used to make device parameters persistent. They are like normal non volatile variables, but set the values of the device parameters with the corresponding name. Every nv variable beginning with nv.dev is a non volatile device variable. They have the form nv.dev.<devname>.<paramname> and act on the parameter <paramname> of the device named <devname>. The non volatile device variables are designated for example for video modes, ethernet device ip addresses or mtd partitioning. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Fixing the dependencies makes it possible to fully use bootm from C without enabling the bootm command support. This also removes the CMD_ prefix from the options which means we have to update the defconfigs aswell. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
