ab25e880ca ppc4xx: POST UART: Use in/out_8() io-accessor functions
This patch fixes a problem in the PPC4xx POST UART driver. This driver
incorrectly used the in/out8() io-accessor functions. This could lead to
problems since these functions don't guarantee execution ordering. This
patch now replaces these functions with the correct ones.

Additionally the driver is converted to using the NS16550 struct instead
of macros for the register offsets.

And some common code is factored out for better maintainability.

cdb749778a Rename getenv_r() into getenv_f()
While running from flash, i. e. before relocation, we have only a
limited C runtime environment without writable data segment. In this
phase, some configurations (for example with environment in EEPROM)
must not use the normal getenv(), but a special function.  This
function had been called getenv_r(), with the idea that the "_r"
suffix would mean the same as in the _r_eentrant versions of some of
the C library functions (for example getdate vs. getdate_r, getgrent
vs. getgrent_r, etc.).

Unfortunately this was a misleading name, as in U-Boot the "_r"
generally means "running from RAM", i. e. _after_ relocation.

To avoid confusion, rename into getenv_f() [as "running from flash"]

a47a12becf Move arch/ppc to arch/powerpc
As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.

Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.

39ff7d5f4c POST: Remove duplicated post_hotkey_pressed() functions
This patch introduces a weak default function for post_hotkey_pressed(),
returning 0, for boards without hotkey support. The long-running tests
won't be started on those boards. This default function was implemented
in many board directories. By implementing this weak default we can
remove all those duplicate versions.

Boards with hotkey support, can override this weak default function
by defining one in their board specific code.

d1c3b27525 ppc4xx: Big cleanup of PPC4xx defines
This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:

- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
  user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines

Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

52cb4d4fb3 stdio/device: rework function naming convention
So far the console API uses the following naming convention:

	======Extract======
	typedef struct device_t;

	int	device_register (device_t * dev);
	int	devices_init (void);
	int	device_deregister(char *devname);
	struct list_head* device_get_list(void);
	device_t* device_get_by_name(char* name);
	device_t* device_clone(device_t *dev);
	=======

which is too generic and confusing.

Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev

This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

ce82ff0538 FPU POST: fix warnings when building with 2.18 binutils
When compile u-boot with the 2.18 binutils the following
warning messages for each object file in post/lib_ppc/fpu/ is
produced at the linking stage:

post/libpost.a(acc1.o) uses hard float, u-boot uses soft-float
...

This is because of the fact that, in general, the soft-float and
hard-float ABIs are incompatible; the 2.18 binutils do checking
of the Tag_GNU_Power_ABI_FP attribute of the files to be linked, and
produce the worning like above if these are not compatible.

The incompatibility of ABIs is concerned only the float values:
e.g. the soft-float ABI assumes the float argument passing in the
pair of rX registers, and the hard-float ABI assumes passing of
the float argument in the fX register. When we don't pass the float
arguments between the functions compiled with different floatness,
then such an application will work correctly.
This is the case for the FPU POST: u-boot (compiled with soft-float)
doesn't pass to (and doesn't get from) the FPU POST functions any
floats; there are no functions exported from the post/lib_ppc/fpu/
objects which would work with float parameters/returns too. So, we
can reassure the linker not to worry about the difference in ABI
attributes of linking files just by setting the 'soft-float'
attribute for the objects in post/lib_ppc/fpu. And this patch does
this.

Also, to avoid passing both soft- and hard-float options in CFLAGS
when compiling the files from post/lib_ppc/fpu (which is OK, but
looks rather dirty) this patch removes the soft-float string from
CFLAGS in post/lib_ppc/fpu/Makefile.

The RTC chip drivers are responsible for providing this info if the
corresponding chip supports such functionality. If not - always
report that the time is reliable.

The CPU POST test code (run from cpu_post_exec_31()) doesn't follow the
ABI carefully, at least the CR3, CR4, and CR5 fields of CR are clobbered
by it. The gcc-4.2 with its more aggressive optimization exposes this fact.
This patch just saves the CR value before running the test code, so allowing
it to do anything it wants with CR.

4b3cc6ece9 ppc4xx: Refactor ECC POST for AMCC Denali core
The ECC POST reported intermittent failures running after power-up on
the Korat PPC440EPx board.  Even when the test passed, the debugging
output occasionally reported additional unexpected ECC errors.

This refactoring has three main objectives: (1) minimize the code
executed with ECC enabled during the tests, (2) add more checking of the
results so any unexpected ECC errors would cause the test to fail, and
(3) use synchronization (only) where required by the processor.

b2e2142c50 POST: Execute SPR test after relocation
On LWMON5 we now use d-cache as init-ram and stack. The SPR POST test uses
self modifying code and this doesn't work with stack in d-cache, since
I can't move the code from d-cache to i-cache. We move the SPR test to
be executed a little later, after relocation. Then stack is located in
SDRAM and this self-modifying code is no problem anymore.

As repoted by Larry Johnson, running "diag run cache" caused a crash
in U-Boot. This problem was introduced by a patch that removed the
TLB entry for the cache test after the test has completed. Since this
TLB was only setup once, a 2nd attempt to run this cache test
failed with a crash. Now this TLB entry is created every time the
routine is called.

Modifications are based on the linux kernel approach and
support two use cases:

  1) Add O= to the make command line
  'make O=/tmp/build all'

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
