The partial linking patch changes how objects are specified to the linker
and breaks boards with an embedded environment.  So we need to tweak the
list of objects we specify via the linker script that go in the gap before
the embedded env to work with this new behavior.  This fixes linker errors
for all the boards in question.

We explicitly link in the initcode.o in the Blackfin linker script, so
there is no need to merge it into the main common object for the linker
to pull in itself.  This also fixes duplicate symbol errors with the new
partial linking logic.

The TI DA850/OMAP-L138/AM18x EVM can be populated with devices
having different maximum allowed CPU clock rating.

The maximum clock the chip can support can only be determined from
the label on the package (not software readable).

Introduce a method to pass the maximum allowed clock rate information
to kernel using ATAG_REVISION. The kernel uses this information to
determine the maximum cpu clock rate reachable using cpufreq.

Note that U-Boot itself does not set the CPU clock rate. The CPU
clock is setup by a primary bootloader ("UBL"). The rate setup by
UBL could be different from the maximum clock rate supported by the
device.

Having a loop with a counter is no timing guarentee for timing
accuracy or compiler optimizations. For e.g. the same loop counter
which runs when the MPU is running at 600MHz will timeout in around
half the time when running at 1GHz. or the example where GCC 4.5
compiles with different optimization compared to GCC 4.4. use timer
to keep track of time elapse and we use an emperical number - 1sec
for a worst case timeout.  This should never happen, and is adequate
imaginary condition for us to fail with timeout.

Fixes build breakage in da830evm after commit
97003756 "da8xx: fixup ARM
relocation support"

The da8xx fixup commit changed da830/da850 common code to make
relocation work in da850, but didn't add the required defines
to da830evm_config.h resulting in build failure in the common code.

This patch adds those defines for da830, but makes no sense without

The Blackfin on-chip BootROM requires that fill operations (which is
used for the bss) be aligned to 4 bytes (base addr and total len).
Plus, the Blackfin early init asm code assumes the same thing.  So
rather than making things work for no real gain, make sure the bss
len is padded to 4 bytes in the linker script.

Since we set #define MORECORE_CLEARS 1, the code assumes 'sbrk' always
returns zero'd out memory.  However since its possible that free()
returns memory back to sbrk() via malloc_trim we could possible get
non-zero'd memory from sbrk().  This is a problem for when code might
call calloc() and expect the memory to have been zero'd out.

There are two possible solutions to this problem.
1. change #define MORECORE_CLEARS 0
2. memset to zero memory returned to sbrk.

We go with the second since the sbrk being called to free up memory
should be pretty rare.

The following code problems an example test to show the issue.  This
test code was inserted right after the call to mem_malloc_init().

...
       u8 *p2;
       int i;

       printf("MALLOC TEST\n");
       p1 = malloc(135176);
       printf("P1 = %p\n", p1);
       memset(p1, 0xab, 135176);

       free(p1);
       p2 = calloc(4097, 1);
       printf("P2 = %p %p\n", p2, p2 + 4097);

       for (i = 0; i < 4097; i++) {
	       if (p2[i] != 0)
		       printf("miscompare at byte %d got %x\n", i, p2[i]);

       free(p2);
       printf("END MALLOC TEST\n\n");

Typo from 4b29bdb0Signed-off-by: NMatthew McClintock <msm@freescale.com>

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.
