This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.NOTE: This patch depends on:

Each cpu directory currently has its own .lds file. This is only needed
in most cases because the start.o file is in a different subdir.Now that we can factor out this difference, we can move most cpus over
to the common .lds file.Signed-off-by: Simon Glass

Boards can select either the 'built-in' parser or the hush parser. We
should not call builtin_run_command() if we are using the hush parser.
We use run_command() instead, since it knows how to call the correct
parser.Signed-off-by: Simon Glass

The current run_command() is only one of the parsing options - the other

In commit 2d575e46859dd9127a9cec731ace77523e6ea2ab a separate header
file was introduced for the DM6467T EVM, include/configs/davinci_dm6467Tevm.h.
The substantial difference between the davinci_dm6467evm and the
davinci_dm6467Tevm configuration is a single bit in the hardware revision
that is passed to the Linux kernel and davinci_dm6467evm has
REFCLK_FREQ = 27000000 where as davinci_dm6467Tevm.h has a
REFCLK_FREQ = 33000000.This patch removes include/configs/davinci_dm6467Tevm.h. Instead the
include/configs/davinci_dm6467evm.h configuration is used for DM6467T EVMs and
renamed CFG_REFCLK_FREQ to CONFIG_REFCLK_FREQ and CONFIG_REFCLK_FREQ is defined
in boards.cfg.Signed-off-by: Prabhakar Lad

This patch fixes booting i.MX28 CPUs via USB download.
In this mode the CPU's bootrom implements a USB HID device that
accepts a bootstream.When downloading the bootstream via USB, first the SPL code is
received and executed. Then the u-boot image is received and
called.The USB bootmode is interrupt driven.
This patch fixes two things:
1) The ARM's fast interrupt mode is disabled when the SPL code
has been run. So save and restore the CPSR register.2) Save and restore c1 control register: the exception vector
location needs to be set back to bootrom space to make the USB
interrupts work again. The SPL code needs to change this
option for the ram size probing.Signed-off-by: Matthias Fuchs

The current implementation invalidates the data cache before turning it
off and causes problems on the hawkboard. See the discussion in
http://lists.denx.de/pipermail/u-boot/2012-January/115212.htmlAccording to the ARM926EJ-S Technical Reference Manual, the cache should
be flushed instead.Also fix the comments to match code.

This patch modifies mxcmmc.c to be used
not only by i.MX27 but also by i.MX31 boards.
Both use the same SD controller, but have different
clock set-ups.
The i.MX27 imx_get_XXXclock functions are made static to
generic.c and a public mxc_get_clock() function
is provided. Pins, base address and prototypes for
an i.MX31 specific board_init_mmc() are provided.
Some of the i.MX27 clock getters are unused and marked
as such to avoid warnings (./MAKEALL -s mx27), but
the code was left in for future use.Signed-off-by: Helmut Raiger

There are 2 locations in the power init code for the mx28 where IRQs are not being cleared because incorrect methods to clear those bits were being used. This was causing my board to get stuck waiting for POWER_CTRL_VDD5V_DROOP_IRQ to clear. Using the correct method to clear the IRQs fixes it.
