Add SPL support to be able to detect a USB Mass Storage device
connected to a USB host. Once a USB Mass storage device is detected
the SPL will load the u-boot.img from a FAT partition to target address.

Using the TPL method for nand boot by sram was already
supported. Here add some code for mpc85xx ifc nand boot.
- For ifc, elbc, esdhc, espi, all need the SPL without
section .resetvec.
- Use a clear function name for nand spl boot.
- Add CONFIG_SPL_DRIVERS_MISC_SUPPORT to compile the fsl_ifc.c
in spl/Makefile;

Some targets will build fine but not boot if sections .hash and
.got.plt are not present in the binary. Add them back.
Also, Exynos machines require .machine_param section in SPL.

When variable size SPL is used, the BL1 expects the SPL to be
encapsulated differently: instead of putting the checksum at a fixed
offset in the SPL blob, prepend the blob with a header including the
size and the checksum.
The enhancements include
- adding a command line option, '--vs' to indicate the need for the
variable size encapsulation
- padding the fixed size encapsulated blob with 0xff instead of random
memory contents
- do not silently truncate the input file, report error instead
- no need to explicitly closing files/freeing memory, this all happens
on exit; removing cleanups it makes code clearer
- profuse commenting
- modify Makefile to allow enabling the new feature per board

Some editors such as Emacs can highlight source files.
But their parser algorithm is not perfect.
If you use one double-quotation alone, some editor cannot
handle it nicely and mark source lines as a string by mistake.
It is preferable to use two double-quotations as a pair.

We have converted all makefiles needed to build $(LIBS).
Until this commit we used to grep switch so that U-Boot style
and Kbuild style makefiles coexist.
But we do not need any more.

Every makefile in sub directories has common lines
at the top and the bottom.
This commit pushes the common parts into script/Makefile.build.
Going forward sub-makefiles only need to describe this part:
COBJS := ...
COBJS += ...
SOBJS := ...
But using obj-y is preferable to prepare for switching to Kbuild.
The conventional (non-Kbuild) Makefile style is still supported.
This is achieved by greping the Makefile before entering into it.
U-Boot conventional sub makefiles always include some other makefiles.
So the build system searches a line beginning with "include" keyword
in the makefile in order to distinguish which style it is.
If the Makefile include a "include" line, we assume it is a conventional
U-Boot style. Otherwise, it is treated as a Kbuild-style makefile.
With this tweak, we can switch sub-makefiles
from U-Boot style to Kbuild style little by little.
obj-y := foo/
syntax (descending into the sub directory) is not supportd yet.
It will be implemented in the upcomming commit.

Due to the nand SPL on some board(e.g. P1022DS)has a size limit, it can
not be more than 4K. So, the SPL cannot initialize the DDR with the SPD
code. This patch introduces TPL to enable a loader stub that is loaded
by the code from the SPL. It initializes the DDR with the SPD or other
operations.
The TPL's size is sizeable, the maximum size is decided by the memory's
size that TPL runs. It initializes the DDR through SPD code, and copys
final uboot image to DDR. So there are three stage uboot images:
* spl_boot, * tpl_boot, * final uboot image

The code from the internal on-chip ROM. It loads the final uboot image
into DDR, then jump to it to begin execution.
The SPL's size is sizeable, the maximum size must not exceed the size of L2
SRAM. It initializes the DDR through SPD code, and copys final uboot image
to DDR. So there are two stage uboot images:
* spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that
ddr spd code can get the interleaving mode setting in env. It loads
final uboot image from offset 96KB.
* final uboot image, size is variable depends on the functions enabled.

SPL defines CONFIG_SPL_BUILD but this does not percolate to the
autoconf.mk Makefile. As a result the build breaks when
CONFIG_SPL_BUILD is used in the board-specific include header file. With
this, there is a possibility of having a CONFIG option defined in the
header file but not defined in the Makefile causing all kinds of build
failure and problems.
It also messes things for up, for example, when one might want to
undefine options to keep the SPL small and doesn't want to be stuck with
the CONFIG options used for U-boot. Lastly, this also avoids defining
special CONFIG_SPL_ variables for cases where some options are required
in U-boot but not in SPL.
We add a spl-autoconf.mk rule that is generated for SPL with the
CONFIG_SPL_BUILD flag and conditionally include it for SPL builds.

Many SPL linker scripts needlessly include linker lists (aka LGAs).
Remove them whenever possible; keep it only in the seven am335x_evm
variants (am335x_evm, am335x_evm_uart[1-5], am335x_evm_spiboot),
where there is actual content in output section .u_boot_list.

This patch adds essential components for generation of the contents of
the linker section that is used by the linker-generated array. All of
the contents is held in a separate file, u-boot.lst, which is generated
at runtime just before U-Boot is linked.
The purpose of this code is to especially generate the appropriate
boundary symbols around each subsection in the section carrying the
linker-generated arrays. Obviously, the interim linker code for actual
placement of the variables into the section is generated too. The
generated file, u-boot.lst, is included into u-boot.lds via the linker
INCLUDE directive in u-boot.lds .
Adjustments are made in the Makefile and spl/Makefile so that the
u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

Move files that are going to be common between T20 and T30 into 'tegra-common'
subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any
files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs
and modified for that SoC. The 'common' files should need only minor changes.
Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a
follow-on patch.
Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean.

This patch adds support for networking in SPL. Some devices are
capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use
existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network
code and environment so far.

Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
framework, enable on all of the previously using boards. We move the
spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave
the NAND one in-place as we plan to replace it later in this series.
We use common/spl to avoid linker problems with respect to merging
constant strings in objects. Otherwise all strings in common/ will be
linked in and kept which grows SPL in size too much.
