Rename board nios2-generic to 3c120_devboard. Since nios2 is
converted to driver model and device tree control of u-boot,
the nios2-generic board directory is removed. We can rename
the board back to a real board name. Now the boards maintained
in u-boot mainline are the same as Linux kernel, namely 3c120
and 10m50.

Do not allocate rx buf in net.c, because altera_tse allocates
its own rx buf in driver. This can save 6KB memory.

This patch moves command line configuration from board header

Though nios2-generic board meant to be a template, it is helpful
to be able to test on a real hardware. As the nios2 linux is
developed and tested on a 3c120 FPGA based Golden Hardware Reference
Design, it makes sense to rebase nios2-generic on this FPGA design.

The definitions for CONFIG_SYS_PROMPT are varied with little reason other

make this the default. The rest of the boards remain unchanged to avoid

The file has a wrong inline keyword of __led_toggle(), which causes

* Adjust the GBL_DATA_OFFSET to account for the fact that we'll be
using the space between that offset and the start of the malloc
region to allocate both a gd structure and a board info structure.
* This fixes a memory corruption bug due to overlap of the malloc
region and the bd_info structure.

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.

This is a generic approach to port u-boot for nios2 boards.
You may find the usage of this approach on the nioswiki,
http://nioswiki.com/DasUBoot
A fpga parameter file, which contains base address information
and drivers declaration, is generated from Altera's hardware system
description sopc file using tools.
The example fpga parameter file is compatible with EP1C20, EP1S10
and EP1S40 boards. So these boards can be removed after this commit.
Though epcs controller is removed to cut the dependency of altera_spi
driver.
