Let all ARM linker scripts handle properly -ffunction-sections
and -fdata-sections. This will be useful for future changes in order to create
symbol-specific sections in common .S files.

Albert's rework of the linker scripts conflicted with Simon's making
everyone use __bss_end. We also had a minor conflict over
README.scrapyard being added to in mainline and enhanced in
u-boot-arm/master with proper formatting.

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.

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 commit keeps all u-boot.bin and u-boot-spl.bin in ARM targets
byte-identical.

This was already used by some SPL targets, and allows the pad amount to
be specified by board config headers rather than only in makefile
fragments.
Also supply a pad-to of zero if the variable is undefined. It works
without this, but this avoids relying on undocumented behavior.

Add section for the linker-generated lists into all possible linker
files, so that everyone can easily use these lists. This is mostly
a mechanical adjustment.

- change CONFIG_ENV_RANGE to contain 2 nand erase blocks,
one for bad block reserve.
- remove from the envvariable "img_writeramdisk" the
ubifsmount command, as it is not needed.
- erase the hole mtd partition containing u-boot
- save environment variable "dvn_app_vers" and "dvn_boot_vers"
only after installing the new image.
changes requested from Marek Vasut:
- arm, davinci: fix eldk-4.2 warnings for cam_enc_4xx board
- get rid of run_command2 usage
needed since patch:
commit 009dde1955
Author: Simon Glass <sjg@chromium.org>
Date: Tue Feb 14 19:59:20 2012 +0000
Rename run_command2() to run_command()
is now in mainline.
- add CONFIG_SPL_LIBGENERIC_SUPPORT support
- remove CONFIG_CMD_PXE support
- fix warning:
cam_enc_4xx.c: In function 'menu_handle':
cam_enc_4xx.c:609: warning: dereferencing type-punned pointer
will break strict-aliasing rules
- fix error:

To avoid a conflict with common/cmd_bootm.c's 'images' (which is
exposed as part of the Linux SPL series), rename the board-specific
'images' to 'imgs'.
