2014-04-02cmd:gpt: randomly generate each partition uuid if undefinedPrzemyslaw Marczak
Changes: - randomly generate partition uuid if any is undefined and CONFIG_RAND_UUID is defined - print debug info about set/unset/generated uuid - update doc/README.gpt Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Piotr Wilczek <p.wilczek@samsung.com> Cc: Tom Rini <trini@ti.com> Cc: Stephen Warren <swarren@nvidia.com> Cc: Lukasz Majewski <l.majewski@samsung.com>
2014-04-02new commands: uuid and guid - generate random unique identifierPrzemyslaw Marczak
Those commands basis on implementation of random UUID generator version 4 which is described in RFC4122. The same algorithm is used for generation both ids but string representation is different as below. char: 0 9 14 19 24 36 xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx UUID: be be be be be GUID: le le le be be Commands usage: - uuid [<varname>] - guid [<varname>] The result is saved in environment as a "varname" variable if argument is given, if not then it is printed. New config: - CONFIG_CMD_UUID Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Stephen Warren <swarren@nvidia.com> Cc: Lukasz Majewski <l.majewski@samsung.com> Cc: trini@ti.com
2014-04-02lib: uuid: add functions to generate UUID version 4Przemyslaw Marczak
This patch adds support to generate UUID (Universally Unique Identifier) in version 4 based on RFC4122, which is randomly. Source: https://www.ietf.org/rfc/rfc4122.txt Changes: - new configs: - CONFIG_LIB_UUID for compile lib/uuid.c - CONFIG_RANDOM_UUID for functions gen_rand_uuid() and gen_rand_uuid_str() - add configs dependency to include/config_fallbacks.h for lib uuid. lib/uuid.c: - add gen_rand_uuid() - this function writes 16 bytes len binary representation of UUID v4 to the memory at given address. - add gen_rand_uuid_str() - this function writes 37 bytes len hexadecimal ASCII string representation of UUID v4 to the memory at given address.

2014-04-02lib: uuid: code refactor for proper maintain between uuid bin and stringPrzemyslaw Marczak
Changes in lib/uuid.c to: - uuid_str_to_bin() - uuid_bin_to_str() New parameter is added to specify input/output string format in listed functions This change allows easy recognize which UUID type is or should be stored in given string array. Binary data of UUID and GUID is always stored in big endian, only string representations are different as follows. String byte: 0 36 String char: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx string UUID: be be be be be string GUID: le le le be be This patch also updates functions calls and declarations in a whole code.

2014-04-02part_efi: move uuid<->string conversion functions into lib/uuid.cPrzemyslaw Marczak
This commit introduces cleanup for uuid library. Changes: - move uuid<->string conversion functions into lib/uuid.c so they can be used by code outside part_efi.c. - rename uuid_string() to uuid_bin_to_str() for consistency with existing uuid_str_to_bin() - add an error return code to uuid_str_to_bin() - update existing code to the new library functions.
