Convert the nds32 architecture to make use of the new asm-generic/io.h
to provide address mapping functions. As the generic implementations are
suitable for nds32 this is primarily a matter of removing code.
Feedback from architecture maintainers is welcome.

Rather than including this arch-specific header file in common.h, include
it from within nds32's u-boot.h header.

Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of <asm-generic/errno.h>. Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.
Now all of include directives for <asm/errno.h> are gone.
Deprecate <asm/errno.h>.

gd->bd->bi_baudrate is a copy of gd->baudrate.
Since baudrate is a common feature for all architectures,
keep gd->baudrate only.
It is true that bi_baudrate was passed to the kernel in that structure
but it was a long time ago.

Include this header to get access to link symbols, which are otherwise
removed.
Signed-off-by: Kuan-Yu Kuo <ken.kuoky@gmail.com>
Cc: Macpaul Lin <macpaul@gmail.com>
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.

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.

This is available on other architectures, and nds32 will start to break

We plan to move architecture-specific data into a separate structure so
that we can make the rest of it common.
As a first step, create struct arch_global_data to hold these fields.
Initially it is empty.
This patch applies to all archs at once. I can split it if this is really
a pain.

This field gets read in one place (by "bdinfo"), and we can replace
