* lib/parameter: Fix typecases to match corresponding PARAM_TYPE_*Andrey Smirnov2018-12-101-2/+2
| | | | | | | | | This change should be a no-op in terms of behavior, but it makes code less confusing when PARAM_TYPE_* matches the type used in the type cast. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* param: make parameter functions more consistentSascha Hauer2017-04-111-112/+78
| | | | | | | | | | | | | | | | | | | | | | This patch creates a consitent set of device parameter functions. With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* parameter: Give device parameters typesSascha Hauer2017-04-101-1/+29
| | | | | | | | This adds a variable type enum and adds this to the device parameters. This information gives the user a hint which values a parameter expects and also helps to organize the parameters better internally. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | param: introduce param_bitmaskSascha Hauer2016-09-221-0/+135
|/ | | | | | | | | | param_bitmask behaves similar to an enum, except that with a bitmask multiple values can be specified. On the command line the bits are represented as a space separated list of strings. In memory a unsigned long * is used as backend storage, this can be modified using the regular bitmap functions.

* Introduce non volatile device variablesSascha Hauer2016-07-061-0/+3
| | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* param_enum: protect against invalid valuesSascha Hauer2015-08-261-2/+6
| | | | | | | | Since dev_add_param_enum is passed a pointer containing the actual value it can contain an invalid value. Protect against it so that we do not access invalid array elements. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The MAC dev parameter functions would only be built when CONFIG_NET is set. This was okay as long as only network devices were using MAC dev params. This has changed with the merge of the state framework, so always compile them in if CONFIG_PARAMETER is set.
