This series adds base support for ST-Ericsson's Ux500 series of Cortex-A9 based
SoCs. Several peripherals are shared with the Nomadik family, for which
support already exists in U-Boot.
Note: The series must be applied on top of the patch "[PATCH V4] Nomadik: fix
reset_timer()" posted by Alessandro Rubini on 2009-11-25:
http://lists.denx.de/pipermail/u-boot/2009-November/064800.html
Cc: Alessandro Rubini <rubini@unipv.it>
Rabin Vincent (8):
Nomadik: move timer code to drivers/misc
Nomadik: move gpio driver to drivers/gpio
nomadik_gpio: get base address from platform code
nomadik_mtu: support configurable clock rates
ARM Cortex A8: ifdef code calling lowlevel init
ux500: add SoC-specific code
pl01x: add support for Ux500 variant of pl011
mop500: add board-specific files

Change the Nomadik GPIO driver to get the base addresses from platform
specific code, since it will be used on multiple platforms with
different base addresses.

the config file. Also remove the hardcoded divisors and do the
calculations based on the configured rate.

Add the base SoC code for ST-Ericsson's Ux500 series of Cortex A9 based
SoCs.
Even though this is a Cortex A9, we put it under Cortex A8 to avoid code
duplication, since the CPU specific code can be used unmodified across
the two CPUs.

The Ux500 variants of the pl011 have separate LCRH registers for RX and
TX. The TX register is at the same offset as the unmodified pl011, so
we need to additionally program only the RX register.

The big change I would like to see with this patchset is for
the arm_cortexa9 cpu be added.

Move the nomadik_gpio.h and nomadik_mtu.h into nomadik.h
Just to have 1 nomadik *.h

May want to just strip the path '(uses ....)' from the comment

It would be better if the #include was not in config file.
Can this be moved to the C files that need it ?

Should a check on the input.
(gpio / 32) < NMK_GPIO_BASE_INDEX_MAX
Add
#define NMK_GPIO_BASE_INDEX_MAX 4
Different values per board
Ok to change the name NMK_GPIO_BASE_INDEX_MAX
to something you like.

TICKS_TO_HZ is only used once.
This macro should be expanded in get_timer() and removed
TICKS_PER_HZ is only used in TICKS_PER_HZ, it should be expanded and removed
TIMER_CLOCK is a remapping of CONFIG_NOMADIK_MTU_CLOCK.
CONFIG_NOMADIK_MTU_CLOCK should just be used

Move this change to the cpu/arm_cortexa9/start.S
That will be created from comment on 6/8

I would rather have arm_cortexa9 be created.
Minimize the duplication by only copying the arm_cortexa8 files
that are needed.
Make this initial copying of a8->a9 its own patch

0 ?
If this is an exception, it should be checked for.
Should also have a comment.
Expected to have U8500_CLKRSTR4_BASE.

Could these structures be added to an arch or board *.h ?

Checking that some of the parameters are expected to be bad.
This function should be split.

This is serial and not ARM.
My opinion is that the board specific #if-def could be cleaner.

nomadik.h is currently used for 8815-specific addresses. If Alessandro
has no objections, I will move it to, say, nmdk8815.h and then combine
the common peripheral headers into nomadik.h.

I believe it's here because this is used by soft_i2c.c. I'll leave it
to Alessandro to decide if he wants to move it out, because this is
8815-specific.

While I preferred the original patch (each peripheral has an header file,
usually), I have no problem with this approach.
Actually, now that "nomadik" is the name of common code (not the
individual cpu), it's correct for "nomadik.h" to have "8815" in the name.

The three arguments to this function come from a table in the SoC
manual. -1 corresponds to the "not used" cells in the table. The
function is better unsplit since the majority of peripherals require
both the register writes to enable their clock.

I've changed this in the other places you mentioned, but for these
GPIOs, I'd prefer to use the pin numbers directly.

Maybe you do, but we don't. Please don't use magic numbers.
