improve device parameter types

improve device parameter types

[Sascha Hauer]

This series improves the device parameter types and also the
global/nv variables. So far we only had 'int' both for signed
and unsigned variables. This series adds support for explicitly
signed or unsigned variables.
Until now the globalvars were all read/write, but some should really
be readonly (like the barebox version for example). This series
adds support for readonly globalvars.

[PATCH 01/10] ARM: socfpga: change param_type struct name

[Sascha Hauer]

We are going to introduce a "enum param_type" in barebox, so
rename the struct type of the same name in the socfpga sequencer
code.

[PATCH 02/10] parameter: Give device parameters types

[Sascha Hauer]

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.

Hi Sascha.

Nitpick mode...

It hurts my eyes to see the missing space between if  and "(".

simple_strtol() suffer from the same issue, but in the rest of the file
there is a space between if and "("

And on top I did not see simple_strtoull() used in the patch series.
But then I may have missed it as I just skimmed the patches.
Everything else I saw looked good.

You're right. The whitespace placing throughout the file doesn't help
reading it. I just sent a patch cleaning it up and also fixed the
whitespaces in this patch.

I'm pretty sure it's used ;)

[PATCH 08/10] param: make parameter functions more consistent

[Sascha Hauer]

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.

[PATCH 09/10] globalvar: make globalvar functions more consistent

[Sascha Hauer]

Similar to the device parameter functions also make the globalvar
functions more consistent. This also adds support for readonly
globalvars and changes several existing globalvars which should
really be readonly to readonly.
