Many platforms duplicate pretty much the same timer code yet they all have
a 32-bit freerunning counter register. Create a common implementation that
minimally requires 2 or 3 defines to add timer support:
CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter
CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter
CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts down
All functions are weak or ifdef'ed so they can still be overriden by any
platform.

This Patch introduce the new i2c_core file, which holds
the I2C core functions, for the rework of the multibus/
multiadapter support.
Also adds changes in i2c.h for the new I2C multibus/multiadapter
support. This new support can be activated with the
CONFIG_SYS_I2C define.

Add hooks for tracing to generic board, including:
- allow early tracing to start early as possible in U-Boot
- reserve memory for trace buffer
- copy early trace buffer to main trace buffer after relocation
- setup full tracing support after relocation

Discard all .dynsym sections from linker scripts
Remove all __dynsym_start definitions from linker scripts
Remove all __dynsym_start references from the codebase
Note: this touches include/asm-generic/sections.h, which
is not ARM-specific, but actual uses of __dynsym_start
are only in ARM, so this patch can safely go through
the ARM repository.

This commit refactors common/board_f.c and common/board_r.c
in order to delete the dest_addr and dest_addr_sp from
gd_t struct.
As mentioned as follows in include/asm-generic/global_data.h,
/* TODO: is this the same as relocaddr, or something else? */
unsigned long dest_addr; /* Post-relocation address of U-Boot */
dest_addr is the same as relocaddr.
Likewise, dest_addr_sp is the same as start_addr_sp.
It seemed dest_addr/dest_addr_sp was used only as a scratch variable
to calculate relocaddr/start_addr_sp, respectively.
With a little refactoring, we can delete dest_addr and dest_addr_sp.

Add generic board support for sandbox. and remove the old board init code.
Select CONFIG_SYS_GENERIC_BOARD for sandbox now that this is supported.

We decided to used unsigned int here, rather than unsigned long. But
for the generic global_data it is still unsigned long. So change it
over.

This file handles common pre-relocation init for boards which use
the generic framework.
It starts up the console, DRAM, performs relocation and then jumps
to post-relocation init.

We create a separate header file for link symbols defined by the link
scripts. It is helpful to have these all in one place and try to
make them common across architectures. Since Linux already has a similar
file, we bring this in even though many of the symbols there are not
relevant to us.
Each architecture has its own asm/sections.h where symbols specifc to
that architecture can be added. For now everything except AVR32 just
includes the generic header.
One change is needed in arch/avr32/lib/board.c to make this conversion
work.

for the unified board series, so create a structure which contains

Add support for newer (up to 2.6.33) kernels
Add zboot command which takes the address of a bzImage as its first

the bzImage size in the header)

MIPS implemetation is different that's why I keep it.
I removed ppc_error_no.h from Marvell boards which
was the same too.
