Add CONFIG_SYS_GENERIC_BOARD to amcc-common.h and CONFIG_DISPLAY_BOARDINFO

CONFIG_SYS_GENERIC_BOARD definition there.

Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.
We can delete the ones in arch and board Kconfig files.
This commit can be easily reproduced by the following command:
find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
N
s/\n[[:space:]]*string//
}

We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.
The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.
After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.
TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

As ppc4xx currently only supports the deprecated nand_spl infrastructure
and nobody seems to have time / resources to port this over to the newer
SPL infrastructure, lets remove NAND booting completely.
This should not affect the "normal", non NAND-booting ppc4xx platforms
that are currently supported.

'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.
All other #define, typedef and enum are removed. They are all consistent with

Note this is a tree-wide change affecting multiple architectures.
At present we use __bss_start, but mostly __bss_end__. This seems
inconsistent and in a number of places __bss_end is used instead.
Change to use __bss_end for the BSS end symbol throughout U-Boot. This
makes it possible to use the asm-generic/sections.h file on all
archs.

Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.
Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.

Currently, some linker scripts are found by common code in config.mk.
Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
sometimes in arch config.mk and sometimes in board config.mk. Some
are found using an arch-specific rule for looking in CPUDIR, etc.
Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.
Replace all of this -- except for a handful of boards that are actually
selecting a linker script in a unique way -- with centralized ldscript
finding.
If board code specifies LDSCRIPT, that will be used.
Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.
If neither of these are specified, then the central config.mk will
check for the existence of the following, in order:
$(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
$(TOPDIR)/$(CPUDIR)/u-boot.lds
Some boards (sc3, cm5200, munices) provided their own u-boot.lds that
were dead code, because they were overridden by a CPUDIR u-boot.lds under
the old powerpc rules. These boards' own u-boot.lds have bitrotted and
no longer work -- these lds files have been removed.

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.

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.

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.
Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

This patch starts a bit PPC4xx header cleanup. First patch mostly
touches PPC440 files. A later patch will touch the PPC405 files as well.

common header ppc405.h and ppc440.h can be cleaned up finally.

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.
However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.
This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:
*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)
I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.
