The recent command clean up to constify the argv option to command funcs
missed the command_t type itself.  This is probably because there are no
build time warnings from it because no one is actually using this thing.
So just punt it rather than fix it.

commit ec50a8e3
"cfi_flash: handle 'chip size exceeds address window' situation"
added 3rd argument to flash_get_size() but didn't fix all the
function calls from the board specific code. Many boards have
their own flash_get_size() definitions in the board code and
use them there, but some boards (e.g. tqm834x, tqm85xx, pdm360ng)
use flash_get_size() from the cfi_flash.c driver.

The bug shows up if the value of the "max_size" argument (which
is not defined when calling the function with two arguments)
happens to be less than "info->size". In this case on the
affected boards we end up with a bank of reduced size and
in the worst case might even be not able to update U-Boot or
to boot the kernel from flash:

=> fli

Bank # 1: CFI conformant FLASH (32 x 16)  Size: 0 kB in 1 Sectors
  AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x227E
  Erase timeout: 4096 ms, write timeout: 1 ms
  Buffer write timeout: 3 ms, buffer size: 64 bytes

  Sector Start Addresses:
  F0000000   RO

Bank # 2: CFI conformant FLASH (32 x 16)  Size: 128 MB in 512 Sectors
  AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x227E
  Erase timeout: 4096 ms, write timeout: 1 ms
  Buffer write timeout: 3 ms, buffer size: 64 bytes

  Sector Start Addresses:
  F8000000        F8040000        F8080000        F80C0000        F8100000
  F8140000        F8180000        F81C0000        F8200000        F8240000
  ...

E.g., updating U-Boot is not possible now:

=> protect off ${u-boot_addr} +${u-boot_size}
Error: end address (0xf007ffff) not in flash!
Bad address format
=> era ${u-boot_addr} +${u-boot_size}
Error: end address (0xf007ffff) not in flash!
Bad address format

This patch removes the 3rd argument of flash_get_size() again
and sets "max_size" in the function itself instead of passing
it as a function argument.

When the cache is enabled in SDRAM we need to flush not only the global

flushed the complete dcache (all dcache lines) via flush_dcache() instead
of adding a flush_dcache_range() call for bd_info since this is faster.

When cache is enabled in the SDRAM area, the values written to SDRAM

Without this patch the POST ECC test failed. Now its working again on

The switch from archive libraries to partial linking has introduced a
number of problems, that are non-trivial to solve.  For example, it is
no longer possible to include individual object files in the linker
script as we did before for example in the case of boards with
embedded environment to fill up the gap caused by the need to align
the environment on flash erase block boundaries.

The best (but unfortunately not easiest) approach to address this
problem is to enable -ffunction-sections (and -fdata-sections) so
we can again (and even in much finer granularity) place certain code
where we want it.  When doing this step, it seems only consequent to
also add --gc-sections which has the added benefit of reducing the
memory footprint of the U-Boot image (both in flash and in RAM).

Unfortunately, this requires changes to a lot of linker scripts.

Apply the same fix for 83xx as was done for 85xx in commit
96196a1f.

Without this, NAND SPLs are built with the text base intended for the main
image, resulting in a broken, very large u-boot-nand.bin.

The block of defines for NAND boot is moved closer to where
CONFIG_SYS_TEXT_BASE is defined.  We can't directly use
CONFIG_SYS_NAND_U_BOOT_DST in the definition of CONFIG_SYS_TEXT_BASE because
autoconf.mk will include the literal text "CONFIG_SYS_NAND_U_BOOT_DST",
but at least keep them close and point out that they're supposed to be
the same.

As we try to get rid of board specific config.mk files we must
provide a way for board specific settings of the LDSCRIPT variable
(path to the linker script) where needed.

We now implement the following hierarchy:

- Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board
  config file.
- If CONFIG_SYS_LDCONFIG is not set, and the system is booting from
  NAND (CONFIG_NAND_SPL is set), then a board specific linker
  script board/$(BOARDDIR)/u-boot-nand.lds gets used.
- If we are not booting from NAND, we test if a processor specific
  linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we
  use that.
- As default, arch/powerpc/config.mk gets used.
