5113ee706d powerpc/85xx:Fix lds for nand boot debug info
Currently "u-boot", the elf file generated via u-boot-nand.lds does not
contain required debug information i.e. .debug_{line, info, abbrev, aranges,
ranges} into their respective _global_ sections.

The original ld script line arch/powerpc/cpu/mpc85xx/start.o
KEEP(*(.bootpg)) is not entirely correct because the start.o file is already
processed by the linker,therefore the file wildcard in "KEEP(*(.bootpg))" will
not process start.o again for bootpg.

So Fix u-boot-nand.lds to generate these debug information.

After relocation of vector table in SDRAM's lower address, IVORs value should
be updated with new handler addresses.

As vector tables are relocated to 0x100,0x200... 0xf00 address in DDR.IVORs
are updated with 0x100, 0x200,....f00  hard-coded values.

For e500 and e500v2 architecturees processor IVPR address should be alinged on
64K boundary.

in start.S, CONFIG_SYS_MONITOR_BASE is stored blindly in IVPR assuming it to be

not point to an exception handler.

96666a39ae DMA: Split the APBH DMA init into block and channel init
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:

219872c8fe ARM1136: add cache flush and invalidate operations
Since commit 5c1ad3e6f8
(net: fec_mxc: allow use with cache enabled) the FEC_MXC
driver uses flush_dcache_range() and invalidate_dcache_range()
functions. This driver is also configured for ARM1136 based
'flea3' and 'mx35pdk' boards which currently do not build
as there are no ARM1136 specific flush_dcache_range() and
invalidate_dcache_range() functions. Add various ARM1136
cache functions to fix building for 'flea3' and 'mx35pdk'.

dde3b70dcf arm: add a common .lds link script
Most ARM CPUs use a very similar link script. This adds a basic
script that can be used by most CPUs.

Two new symbols are introduced which are intended to eventually be
defined on all architectures to make things easier for generic relocation
and reduce special-case code for each architecture:

__image_copy_start is the start of the text area (equivalent to the
existing _start on ARM). It marks the start of the region which must be
copied to a new location during relocation. This symbol is called
__text_start on x86 and microblaze.

__image_copy_end is the end of the region which must be copied to a new
location during relocation. It is normally equal to the start of the BSS
region, but this can vary in some cases (SPL?). Making this an explicit
symbol on its own removes any ambiguity and permits common code to always
do the right thing.

This new script makes use of CPUDIR, now defined by both Makefile and
spl/Makefile, to find the directory containing the start.o object file,
which is always placed first in the image.

To permit MMU setup prior to relocation (as used by pxa) we add an area
to the link script which contains space for this. This is taken
from commit 7f4cfcf. CPUs can put the contents in there using their
start.S file. BTW, shouldn't that area be 16KB-aligned?

2866903b3e arm: Check for valid FDT after console is up
When using CONFIG_OF_CONTROL, add a check that we have a valid FDT
and panic() if not. This must be done after the console is ready.

87f938c9f7 tegra: usb: Add support for Tegra USB peripheral
This adds basic support for the Tegra2 USB controller. Board files should
call board_usb_init() to set things up.

Configuration is performed through the FDT, with aliases used to set the
order of the ports, like this fragment:

        aliases {
		/* This defines the order of our USB ports */
                usb0 = "/usb@0xc5008000";
                usb1 = "/usb@0xc5000000";
        };

ed2974493e tegra: fdt: Add function to return peripheral/clock ID
A common requirement is to find the clock ID for a peripheral. This is the
second cell of the 'clocks' property (the first being the phandle itself).

1c1cce99d4 tegra: usb: fdt: Add additional device tree definitions for USB ports
This adds clock references to the USB part of the device tree for U-Boot,
and marks USB1 as supporting legacy mode (which we disable in the driver).

The USB timing information may vary between boards sometimes, but for
now we hard-code it in C. This is because all current T2x boards use
the same values, we will deal with T3x later and we first need to agree
on the format for this timing information in the fdt and may in fact
decide that it has no place there.

1f1a02123c tegra: fdt: Add clock bindings
This adds a basic binding for the oscillator and peripheral clocks. The
second cell is the clock number, defined as the bit number within the clock
enable register if the peripheral clock.

This uses the RFC clock bindings from Grant Likely so may change later:

d8bd820935 arm: Tegra2: Fix ELDK42 gcc failure with inline asm stack pointer load
The 4.2.2 gcc in the ELDK42 release doesn't like the direct SP
load using a constant in tegra2_start. Change it to use a load
thru another reg using mov sp, %0 : : "r"(CONST).

Tested on my Seaboard T20-A03, U-Boot loads and runs OK. Also
compiled all tegra2 builds with both gcc 4.2.2 and 4.4.1 OK.
