[PATCH v3 0/4] Consolidate and clean up the arch/arm/mach-mx5/mm-*.c

[Jason Liu]

The patch-set work for consolidate and clean up the arch/arm/mach-mx5/mm-*.c

Jason Liu (4):
  ARM: i.MX5/mm: Consolidate arch/arm/mach-mx5/mm-*.c
  ARM: i.MX5/mm: Remove MX51_DEBUG related mapping
  ARM: i.MX5/mm: add the TZIC mapping resource
  ARM: i.MX5/mm: use static mapping for TZIC

---
v3: remove the TZIC for i.mx51 TO1 since there is no support for TO1 now.
    add missing static mapping comments for the i.mx53 part
    split the patches to 1) remove DEBUG mapping 2) add TZIC mapping

v2: Remove the MX51_DEBUG related mapping which is conflict with TZIC.
    MX51_DEBUG related mapping is dead code, no-one use it.

[PATCH v3 1/4] ARM: i.MX5/mm: Consolidate arch/arm/mach-mx5/mm-*.c

[Jason Liu]

We don't need one seperate file to deal with i.mx50
related stuff, which is very similar with i.mx51/53.
We can put it together into one file.So, just merge
function from mm-mx50.c to mm.c and remove mm-mx50.c

No function change by this commit.

[PATCH v3 4/4] ARM: i.MX5/mm: consolidate TZIC map code

[Jason Liu]

We can use static mapping for TZIC to get rid of the
duplicated code for ioremap and the error handling of
ioremap, which will made code more clean and consistent

This patch also removes TZIC mapping for i.mx51 TO1 since
there is no support for TO1 now since the following commit:

I'd prefer to have the i.MX50 stuff above i.MX51, not below i.MX53.
Applies to the other items, too.

Best regards

The numbers are right, but using small letters would be more consistent.
Hmm, it seems I wasn't attentive when the mx53 mapping was introduced
...

Other than that this should be folded into patch 4 IMHO.

[PATCH v3 4/4] ARM: i.MX5/mm: consolidate TZIC map code

Something like

	9ab4650 (ARM: imx: Get the silicon version from the IIM module)

instead of the full hash without shortlog is generally preferred here. I
usually use

	git one 9ab4650f718a0e1cb8792bab4ef97efca4ac75c2

to get this (after doing

	git config --global alias.one "show -s --pretty='format:%h (%s)'"

once).

Best regards
Uwe
