U-Boot has supported two kinds of asm-offsets.h.
One is generic for all architectures and its source is located at
./lib/asm-offsets.c.
The other is SoC specific and its source is under SoC directory.
The problem here is that only boards with SoC directory can use
the asm-offsets infrastructure.
Putting asm-offsets.c right under CPU directory does not work.
Now a new demand is coming. PowerPC folks want to use asm-offsets.
But no PowerPC boards have SoC directory.
It seems inconsistent that some boards add asm-offsets.c to SoC
directoreis and some to CPU directories.
It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib.
This commit merges asm-offsets.c under SoC directories into
arch/$(ARCH)/lib/asm-offsets.c.
By the way, I doubt the necessity of some entries in asm-offsets.c.
I am leaving refactoring to the board maintainers.
Please check "TODO" in the comment blocks in
arch/{arm,nds32}/lib/asm-offsets.c.

Some version of Andes core support FPU coprocessor,
if this is the case, and toolchain support FPU instruction set,
we should enable it at low level initialization time.

The timer3 counter unit for lastdesc and now values are inconsistent in current
code. The unit of "readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2)" is
second. However, CONFIG_SYS_HZ is defined as 1000 in board config file.
This means the accuracy of "lastdec" and "now" should be in millisecond,
thus fix the equation to set lastdec and now variables accordingly.

The original adp-ag101/adp-ag101p initialize only one bank(64MB)
by default at boot time, but it is not enough for some application,
so increasing to two banks(128M).

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.

The command declaration now uses the new LG-array method to generate
list of commands. Thus the __u_boot_cmd section is now superseded and
redundant and therefore can be removed. Also, remove externed symbols
associated with this section from include/command.h .

This commit does the following updates.
1. Split the common cache access from cpu.c into lib folder.
2. Rename the following cache api to adapt common.h
- dcache_flush_rang -> flush_dcache_rang
- icache_inval_range -> invalidate_icache_range
3. Add invalidate_dcache_range

SoC ag101 is the first chip using NDS32 N1213 cpu core.
Add header file of device offset support for SoC ag101.
Add main function of SoC ag101 based on NDS32 n1213 core.
Add lowlevel_init.S and other periphal related code.
This version of lowlevel_init.S also replace hardcode value

Add N1213 cpu core (N12 Core family) support for NDS32 arch.
This patch includes start.S for the initialize procedure of N1213.
Start procedure:
start.S will start up the N1213 CPU core at first,
then jump to SoC dependent "lowlevel_init.S" and
"watchdog.S" to configure peripheral devices.
