139e1875d3 PPC: fix "Warning: FOO uses hard float, BAR uses soft float".
It appears that with recent versions of GCC the explicit
"-mhard-float" command line option takes precedence over the
``asm(".gnu_attribute 4, 2");'' in the source file, so this no longer
helps to avoid the warnings we get when linking code that uses FP
instructions with other code that was built using soft-float.

We can remove the ".gnu_attribute" (which appears to carry no other
information, at least so far) from the object files, but we also have
to make sure we don't pull in the __gcc_qsub() and __gcc_qmul()
functions from the standard libgcc, as these would again "infect" our
linking.  We copy this code from:
	gcc-4.2.2/gcc/config/rs6000/darwin-ldouble.c
This old version was chosen because it was still available under a
compatible license (GCC v2+).   The file was stripped down to the
needed parts, and reformatted so it passes checkpatch with only one
warning (do not add new typedefs).

8d3fcb5e60 POST: add new memory regions test
This test is similar to the actual POST memory test but quicker and
far less complete. It checks the address and data lines and then only
tests some regularly placed sub regions of the RAM.
This can be useful when we want to test the RAM but we do not have enough
time to run the full memory test.

The POST memory test code was rearranged in order to avoid code duplication
between the two tests but the memory test functionnality remains the same.

212a0cafad POST: make env test flags fetching optional
Some boards have the environment variables defined in a slow EEPROM. post_run
accesses these environment variables to define which tests have to be run (in
post_get_flags). This is very slow before the code relocation on some boards
with a slow I2C EEPROM for environement variables.

This patch adds a config option to skip the fetching of the test flags in the
environment variables. The test flags assigned to the tests then only are the
ones statically defined for the test in post/tests.c.

79843950b2 POST: add post_log_res field for post results in global data
The current post_log_word in global data is currently split into 2x
16 bits: half for the test start, half for the test success.
Since we alredy have more than 16 POST tests defined and more could
be defined, this may result in an overflow and the post_output_backlog
would not work for the tests defined further of these 16 positions.

An additional field is added to global data so that we can now support up
to 32 (depending of architecture) tests. The post_log_word is only used
to record the start of the test and the new field post_log_res for the
test success (or failure). The post_output_backlog is for this change
also adapted.

975afc34dd post: fix indendation/brace confusion
The post.c code is missing braces around the pass case, and as a
result, the diagnostic function will post both fail and pass for
a failed test.  The reason for this bug is probably the incorrect
indentation used, so when reading the code it seems like there
are proper braces.

Indent the code to the correct depth and put proper braces around
the "else" branch of the "if" statement.

e009cdeb63 powerpc: Fix FPU post related link warnings
If we built POST on PPC's that didn't enable CONFIG_SYS_POST_FPU we'd
get the following warning with newer toolchains:

powerpc-linux-gnu-ld: Warning: lib_powerpc/fpu/libpostpowerpcfpu.o
		      uses hard float, libpost.o uses soft float

We actually worked around this sometime ago with the following commit:

commit ce82ff0538

Date:   Sat Dec 20 14:54:21 2008 +0300

   FPU POST: fix warnings when building with 2.18 binutils

However, this only took into effect if CONFIG_SYS_POST_FPU was enabled.
We can simply move the GNU_FPOST_ATTR out of the CONFIG_SYS_POST_FPU
ifdef block to address the issue.

ac69243d83 ppc4xx/POST: Change ethernet test loop count to a default of 10
This patch changes the PPC4xx ethernet POST loop test count from
currently 192 (256 - 64) to a default of 10. While doing this the max
frame size is increased. Each loop run uses a different frame size,
starting with a max of 1514 bytes, down to 64. The default loop
count of 10 can be overriden using CONFIG_SYS_POST_ETH_LOOPS in the
board config header.

The TEST_NUM loop has been removed as it was never used.

The main reason for this change is to reduce the boot time on boards
using this POST test, like the lwmon5 board. This change reduces the
boot time by about 600ms on the lwmon5 board.

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.

9d921f19b3 post/i2c: Add ability to ignore I2C devices
Add the ability to not report an I2C POST error for a set of given I2C
addresses on bootup.  This is useful for cases when a device may or may
not be present, and neither case is considered an error.  For example:

- Some form factors such as XMC and Compact PCI Express have an I2C
  EEPROM whose address changes based on geographical address.  Eg
  installed in one slot its EEPROM address is, 0x50, in another its
  0x51, etc.  This allows multiple devices to have their EEPROMs present
  on the same I2C bus.  Thus the I2C devices present for an XMC or
  CPCIe card depend on if and where other cards are installed in the
  same system.

- Some cards have optional I2C devices.  Eg one hardware build
  configuration has different I2C devices than another and software
  can't determine if the optional device should be present or not.

- Some cards have optional daughtercards with I2C devices on them.

- I2C EEPROMs address range depends on their size.  Its possible to
  support differently size EEPROMs by only probing the EEPROM's base
  address and ignoring the other addresses that are impacted by its
  size.

A new CONFIG_SYS_POST_I2C_IGNORES define has been added which specifies
a list of I2C addresses for the I2C POST to ignore.

9f949c9ac2 post/i2c: Don't probe address 0
According to the I2C specification device address 0 is the "general call
address", ie a broadcast address.  The I2C specification states that the
format of a general call uses at least 2 bytes, which U-Boot's probing
routine does not adhere to.

Not probing device address 0 will prevent possible issues with devices
that accept general calls.  Additionally, this change shouldn't reduce
POST coverage since each I2C device should still be accessed via its
own, unique address.

Also the common CONFIG_SYS_NS16550_COMx defines are now used

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"]

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

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.
