09743ba635 tegra2: Always build with USE_PRIVATE_LIBGCC=yes.
The AVP on Tegra2 doesn't boot properly when U-Boot is linked against
the GCC provided libgcc. To work around this, always build and link
against a private libgcc for Tegra2-based boards.

e2132c29d8 arm: Tegra: fix undefined instruction hang immediately after reset
commit 0d479b53 (Aneesh V) added code for OMAP4 that doesn't
execute on Tegra, due to the AVP (ARM7TDI) not having a CP15.
Result was an undefined instruction hang just after reset.

18936ee2ad i.mx: introduce the armv7/imx-common folder
In order to support the coming MX6 platform and to reducde
the duplicated code, we had better move some common files
or functions to the imx-common folder for sharing.

This patch does the following:
- move speed.c file from armv7/mx5/speed.c to armv7/imx-common/speed.c
- move armv7/mx5/timer.c to armv7/imx-common/timer.c, no any new feature
  added but just fix the checkpatch errors in the old file and remove
  the CONFIG_SYS_MX5_CLK32 reference in the file
- create one new file cpu.c file to store the common function with i.mx5/6

In board_init_f() the gd->bd pointer is not valid when dram_init() is called.
This only avoids dying because DRAM is at zero on Tegra2. The common ARM

80433c9ac6 arm: Move CP15 init out of cpu_init_crit()
Some SOCs have do not start up with their 'main' CPU. The first U-Boot
code may then be executed with a CPU which does not have a CP15, or not a
useful one.

Here we split the initialization of CP15 into a separate call, which can
be performed later if required.

Once the main CPU is running, you should call cpu_init_cp15() to perform
this init as early as possible.

Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not
need to change, this CP15 init is still skipped in that case. The only
impact for these boards is that the cpu_init_cp15() will be available
even if it is never used on these boards.

210576fc5e tegra2: Simplify tegra_start() boot path
The Tegra2 boot path is more complicated than it needs to be. Since we want
to move to building most of U-Boot with ARMv7 and only a small part with
ARMv4T (for AVP) it should be as simple as possible.

This makes tegra2_start() into a simple function which either does AVP
init or A9 init depending on which core is running it. Both cores now
following the same init path, beginning at _start, and the special Tegra2
boot path code is no longer required.

Only two files need to be built for ARMv4T, and this is handled in the
Tegra2 CPU Makefile.

e43d6ed932 tegra2: Add arch_cpu_init() to fire up Cortex-A9
We want to move away from a special Tegra2 start-up, and just use
arch_cpu_init() instead. However, if we run board_init_f() from boot
we need to build it for ARMv4T, since the Tegra's AVP start-up CPU
does not support ARMv7.

The effect of this is to do the AVP init earlier, and in
arch_cpu_init(), rather that board_early_init_f().

dc7100f408 armv7: disable L2 cache in cleanup_before_linux()
We were not disabling external caches before jumping
to kernel. We were flushing all caches including
external caches and disabling caches globally in
CP15 System Control register. Apparently this is not
enough.

The bootstrap loader in Linux kernel that does decompression
enables data-caches again, flush them after use and disable
them before jumping to kernel proper. However, it's not aware
of the external caches.

Since we have left external cache enabled, external cache will
get used once caches are enabled globally, but it's not flushed
because decompressor is not aware of external caches. When it
jumps to kernel with caches disabled globally, we have stale
data in the external cache and a coherency problem.

This was breaking the boot for OMAP4 with latest mainline
kernel. The solution is to disable external caches in
cleanup_before_linux(). With this fix kernel is booting again.

78f455c055 omap4/5: Add support for booting with CH.
Configuration header(CH) is 512 byte header attached to an OMAP
boot image that will help ROM code to initialize clocks, SDRAM
etc and copy U-Boot directly into SDRAM. CH can help us in
by-passing SPL and directly boot U-boot, hence it's an alternative
for SPL. However, we intend to support both CH and SPL for OMAP4/5.

Initialization done through CH is limited and is not equivalent
to that done by SPL. So U-Boot has to distinguish between the
two cases and handle them accordingly. This patch takes care
of doing this.

41c881c0ca mx53: Turn off child clocks before reconfigure perclk_root
In addition to ensuring that PERCLK remains at least 2.5 times slower
than the AHB clock, certain steps need to be followed to ensure robust
operation of PERCLK when reconfiguring the PERCLK clock source.

To properly configure the PERCLK clock source, the following steps are
required:

1.In the CCGR registers, gate the clocks to all PERCLK-dependent
  modules.
2.Select the desired input clock for the PERCLK root clock (to be either
  source from the peripherals main source clock or the
  lp_apm clock source). Refer to the CMCBR register,  perclk_lp_apm_sel bit.
3.Configure the perclk_pred1, perclk_pred2, and perclk_podf dividers
  to the desired setting.  Refer to the CBCDR register for details.
4.In the CCGR registers, enable the desired clocks for the
  PERCLK-dependent module clocks.

If these steps aren't followed, GPT timer may stop and the kernel stops
at "Calibrating delay loop".

cca4e4aec1 Reduce build times
U-Boot Makefiles contain a number of tests for compiler features etc.
which so far are executed again and again.  On some architectures
(especially ARM) this results in a large number of calls to gcc.

This patch makes sure to run such tests only once, thus largely
reducing the number of "execve" system calls.

Example: number of "execve" system calls for building the "P2020DS"
(Power Architecture) and "qong" (ARM) boards, measured as:
	-> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board>
	-> grep execve /tmp/foo | wc -l

	Before: After:	Reduction:
==================================
P2020DS 20555	15205	-26%
qong	31692	14490	-54%

As a result, built times are significantly reduced, typically by
30...50%.

efb2172ece Move timestamp and version files into 'generated' subdir
There is a rather subtle build problem where the build time stamp is not
updated for out-of-tree builds if there exists an in-tree build which
has a valid timestamp file. So if you do an in-tree build, then an
out-of-tree build your timestamp will not change.

The correct timestamp_autogenerated.h lives in the object tree, but it
is not always found there. The source still lives in the source tree and
when compiling version.h, it includes timestamp_autogenerated.h. Since
the current directory is always searched first, this will come from the
source tree rather than the object tree if it exists there. This affects
dependency generation also, which means that common/cmd_version.o will not
even be rebuilt if you have ever done an in-tree build.

A similar problem exists with the version file.

This change moves both files into the 'generated' subdir, which is already
used for asm-offsets.h. Then timestamp.h and version.h are updated to
include the files from there.

There are other places where these generated files are included, but I
cannot see why these don't just use the timestamp.h and version.h headers.
So this change also tidies that up.

I have tested this with in- and out-of-tree builds, but not SPL. I have
looked at various other options for fixing this, including sed on the dep
files, -I- and -include flags to gcc, but I don't think they can be made
to work. Comments welcome.

9db1bfa110 ARM: MX51: PLL errata workaround
This is a port of the official PLL errata workaround from Freescale to
mainline u-boot.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.

1e463866f5 omap4: automatic sdram detection
Identify SDRAM devices connected to EMIF automatically:
LPDDR2 devices have some Mode Registers that provide details
about the device such as the type, density, bus width
etc. EMIF has the capability to read these registers. If there
are no devices connected to a given chip-select reading mode
registers will return junk values. After reading as many such
registers as possible and matching with expected ranges of
values the driver can identify if there is a device connected
to the respective CS. If we identify that a device is connected
the values read give us complete details about the device.

This along with the base AC timings specified by JESD209-2
allows us to do a complete automatic initialization of
SDRAM that works on all boards.

Please note that the default AC timings specified by JESD209-2
will be safe for all devices but not necessarily optimal. However,
for the Elpida devices used on Panda and SDP the default timings
are both safe and optimal.

aadcfc179a OMAP[34]: fix broken timer
As implemented now the timer used to implement __udelay counts
to 0xffffffff and then gets stuck there because the the programmed
reload value is 0xffffffff.  This value is not only wrong but
illegal according to the reference manual.

One can reproduce the bug by leaving a board at the u-boot prompt
for sometime then issuing a sleep command.  The sleep will hang
forever.

The timer is a count up timer that reloads as it rolls over
from 0xffffffff so the correct load value is 0.

Change TIMER_LOAD_VAL from 0xffffffff to 0 and introduce
a new constant called TIMER_OVERFLOW_VAL set to 0xffffffff.

  opertions will affect both L1 and L2 caches. In Cortex-A9
  these will affect only L1 cache

- D-cache operations supported:

	- Invalidate D-cache range
	- Flush(clean & invalidate) entire D-cache
	- Flush D-cache range
- I-cache operations supported:
	- Invalidate entire I-cache

- Add maintenance functions for TLB, branch predictor array etc.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

e03f316974 Drop support for CONFIG_SKIP_RELOCATE_UBOOT
For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE).  The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().

With ELF relocation, this does not work like that any more, and
related boards need to be fixed anyway.  So don't keep this relict any
longer.

When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation

implementation (ELF relocation), where this no longer works.  By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.

So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

0e7b62179f ARMV7: OMAP: Move syslib.c to omap-common since it can be shared by OMAP3 and OMAP4
The functions in syslib.c can be shared, so this patch moves it from
cpu/omap3 to cpu/omap-common

f70409aff3 ARMV7: S5P: separate the peripheral clocks
Because of peripheral devices can select clock sources,
separate the peripheral clocks. (pwm, uart and so on)
It just return the pclk at s5pc1xx SoC,
but s5pc210 SoC must be calculated by own clock register setting.

37168dab52 ARMV7: S5P: rename from s5pc1xx to s5p
Because of these are common files around s5p Socs, rename from s5pc1xx to s5p.
And getting cpu_id is SoC specific, so move to SoC's header file.

d93d0f0cfe S5P: Use accessor functions instead of SoC specific defines to access the base address
This patch is intended to prepare the other S5P SoC. (s5pc210)
If use SoC specific defines then can't share with other SoC.
So, make the accessor functions for access the base address by common way.

51b5870bdc MX51EVK: fix return value of get_timer_masked
get_timer_masked() should return current timestamp,
not current ticks from hardware register.

Tested on one custom board with NAND flash.
Without this patch, NAND write always TIMEOUT
because get_timer(0) return a big value.

This patch applies for u-boot-2010.06

674e0b217f ARMV7: Fix udelay for OMAP4
The OMAP4 x-load code sets gptimer1 clock source to 32Khz.  This isn't
acceptable for udelay.  This patch changes from gptimer1 to gptimer2,
which uses sys_clk at 38.4 Mhz.

f56348af5d ARM: Rename arch/arm/cpu/arm_cortexa8 to armv7
The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9

Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.

The two architectures are similar enough that substantial code can be shared.
