[U-Boot] [PATCH v2 1/4] mxs: Remove not required explicit iomux-mx28.h include

[Otavio Salvador]

The iomux header is included on sys_proto.h so to avoid SoC specific
header inclusion.

[U-Boot] [PATCH v2 2/4] mxs: Remove not required include of iomux-mx28.h

[Otavio Salvador]

The iomux-mx28.h include is not required on spl_mem_init.c so it has
been droped.

[U-Boot] [PATCH v2 3/4] mxs: rename regs-clkctrl.h to regs-clkctrl-mx28.h

[Otavio Salvador]

The CLKCTRL registers are SoC specific so we ought to have it clear on

[U-Boot] [PATCH v2 4/4] mxs: Convert sys_proto.h prefixes to 'mxs'

[Otavio Salvador]

The sys_proto.h functions (except the boot modes) are compatible with
i.MX233 and i.MX28 so we use 'mxs' prefix for its methods.

Well, this is not clear - maybe because I do not know your plan. I
suppose that general header, that is imx-regs.h, and drivers such as
ehci-mxs should not include SOC specific headers, so that they can be
used with both SOCs. The indirection should be done in a deeper level.

Both includes currently headers referred to the specific function (gpmi,
bch, base, ...), not to a specific SOC. Then I am expecting that inside
regs-clkctrl.h (or another header) there are details for both SOCs, or
if you want to split they completely, regs-clkctrl.h is something like

regs-clkctrl.h:

#ifdef MX28
include <asm/arch/regs-clkctrl-mx28.h>
#else #ifdef MX23
include <asm/arch/regs-clkctrl-mx23.h>
....

This is indeed the idea; I didn't include this change yet to add it
when including mx23 changes. If you prefer I can send a new version of
it moving the .h to a deeper level. I am OK in doing that as it'd be
done anyway later.

Well, this is not a stop point - I wanted only to understand which is
the final result. I think we agree all what we want. I have no problem
to take this as temporary patch, fixed by another patch later.

Great; so please take this one and I send new patches once I finish
the mx23 addition.
