0390e26705 common/Makefile: don't include env_embedded.o into libcommon
Some boards use an embedded environment, where env_embedded.o has to
be linked at a special position in the U-Boot image; to make this
possible, we do not include it into libcommon.o for such boards.

6163f5b4c8 malloc: Fix issue with calloc memory possibly being non-zero
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");

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.

983eb9d162 pci: Clean up PCI info when CONFIG_PCI_SCAN_SHOW
This change does the following:
- Removes the printing of the PCI interrupt line value.  This is
  normally set to 0 by U-Boot on bootup and is rarely used during
  everyday operation.

- Prints out the PCI function number of a device.  Previously a device
  with multiple functions would be printed identically 2 times, which is
  generally confusing.  For example, on an Intel 2 port gigabit Ethernet
  card the following was displayed:
    ...
    04  01  8086  1010  0200  00
    04  01  8086  1010  0200  00
    ...

- Prints a text description of each device's PCI class instead of the
  raw PCI class code.  The textual description makes it much easier to
  determine what devices are installed on a PCI bus.

- Changes the general formatting of the PCI device output.

a9aa392629 Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC
When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support.  However, other recent changes led to a different
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.

c4b115f536 hwconfig: Utilize getenv_f before relocation to allow for larger buffer
Since we use hwconfig in cases before relocation (like getting DDR
params on FSL PPC systems), we can have strings that exceed the early
small (32 byte) buffer size that getenv will handle.

So we explicitly allocate our own buffer on the stack and use if to
handle getting the hwconfig env string.  We currently utilize a string
length of 128 bytes.

This allows us to get rid of boot messages like:

env_buf too small [32]

43b08af53e always relocate fdt into an lmb-allocated memory block
The device tree (fdt) must always exist in within the bootmap (usually the
first 16MB of RAM).  If it doesn't, then boot_relocate_fdt() will allocate
an LMB region in the bootmap and copy the fdt into that region.  It will
also increase the size of the fdt.

If the fdt is already in the bootmap, then previously the memory was just
reserved.  There was no contingency if the reservation failed, however.

By always allocating an lmb region and copying/resizing the fdt into that
region, the code is simplified and the memory region is always allocated
properly.

Also change the types of some variables to avoid some typecasts.

5a75e12107 FDT: only call boot_get_fdt from generic code
All arches except nios2 and microblaze call boot_get_fdt
from bootm_start in common/cmd_bootm.c.

Having nios2 and microblaze do so as well removes code from
their respective do_bootm_linux routines and allows removal of
a nasty ifdef from bootm_start.

In the case where boot_get_fdt returns an error bootm_start
returns and the platform specific do_bootm_linux routines
will never get called.

Also only check argv[3] for an fdt addr if argc > 3 first.
This is already the case for nios2.

758b39979d common/image.c fix length calculation in boot_relocate_fdt
boot_relocate_fdt is called on platforms with CONFIG_SYS_BOOTMAPSZ
defined to relocate the device tree blob to be inside the
boot map area between bootmap_base and bootmap_base+CONFIG_SYS_BOOTMAPSZ.

For the case where the blob needs to be relocated, space is
allocated inside the bootmap by calling lmb_alloc_base with
size passed in plus some padding:

    of_len = *of_size + CONFIG_SYS_FDT_PAD;

For the case where the blob is already inside the bounds of the boot map
area, lmb_reserve is called to reserve the the space where the blob is
already residing.  The calculation for this case is currently:

    of_len = (CONFIG_SYS_BOOTMAPSZ + bootmap_base) - (ulong)fdt_blob;

This is wrong because it reserves all the space in the boot map area
from the blob to the end ignoring completely the actual size. The
worst case is where the blob is at the beginning and the entire boot map
area get reserved. Fix this by changing the length calculation to this:

    of_len = *of_size + CONFIG_SYS_FDT_PAD;

This bug has likely never manifested itself because bootm has never
been called with the fdt blob already in the bootmap area.  In my
testing on an OMAP3 beagle board I initially worked around the bug
by simply moving the initial location of the fdt blob.  I have tested
with the new calculation with the fdt blob both inside and outside
the boot map area.

Notably, it allows each LUN of GuruPlug's microSD card reader to be

076f1be8e1 TSI148: Fix argument parsing
This patch does 2 things:
 - Fix the argument number assigned to the vdw (VME data width) value.
   Previously, a nonexistent 7th arument was read as the vdw variable.

 - Reduce the size of the argument array for the tsi148 command from
   8 to 7.  The tsi148 command itself is argument index 0, and the
   maximum number arguments passed to the command is 6, making a total
   of 7 for the array.

eaadb44edf cp/cmp: Add WATCHDOG_RESET in copy and compare loop
On some boards with a very short watchdog timeout, the "cp" and
"cmp" commands may reset the board. This patch adds some
watchdog resets inside the loops. Otherwise for example the lwmon5
board will reset while doing something like this:

=> cp.b fc000000 1000000 100000

7f0d241d5c led_display: split led display support into generic and hw-dependent parts
Split the display command into generic interface and hardware-specific
realization for PDSP188x LED display found on hmi1001 and manroland
boards. Simple interface for LED displays is defined in
include/led-display.h and described in doc/README.LED_display.
Driver-specific implementation was moved into drivers/misc/pdsp188x.c
file (enabled with CONFIG_PDSP188x set).

beca5a5f5b fdt_support: support adding EDID property to FDT display nodes
Boards can pass display timing info for drivers using EDID
block. Provide common function to add board specific EDID
data to the device tree. Subsequent patch makes use of this
functionality.

Detailed timing descriptor data from EDID is used for
programming the display controller. This is currently
implemented on the Linux side by the fsl-diu-fb frame
buffer driver and it is documented there in
Documentation/powerpc/dts-bindings/fsl/diu.txt.

Consolidate some code in mtd_get_len_incl_bad(), and fix a condition
where a valid partition could be reported as truncated if it has a
good block at the end of the device (unlikely, since the BBT is usually
there).

Fix mid-block declarations in net_part_size().

59a50d2de1 mtdparts: new add.spread: add part skipping bad blocks
This patch adds a new 'mtdparts add' variant: add.spread. This command variant
adds a new partition to the mtdparts variable but also increases the partitions
size by skipping bad blocks and aggregating any additional bad blocks found at
the end of the partition.

ca75b20ebb mtdparts: add new sub-command "spread"
This patch introduces the 'spread' sub-command of the mtdparts command.
This command will modify the existing mtdparts variable by increasing
the size of the partitions such that 1) each partition's net size is at
least as large as the size specified in the mtdparts variable and 2)
each partition starts on a good block.

The new subcommand is implemented by iterating over the mtd device
partitions and collecting a bad blocks count in each -- including any
trailing bad blocks -- and then modifying that partitions's part_info
structure and checking if the modification affects the next partition.

This patch is based on a port of the 'dynnamic partitions' feature by
Harald Welte <laforge@gnumonks.org>; ported from commit
e05835df019027391f58f9d8ce5e1257d6924798 of
git://git.openmoko.org/u-boot.git. Whereas Harald's feature used a
compile-time array to specify partitions, the feature introduced by
this patch uses the mtdparts environment variable.
