7dfb060291 nios2: move gd and bd into BSS
As suggested by Graeme Russ, move gd and bd data structrures
to BSS instead of calculating the locations around the stack
and heap.

219f4788d3 hush.c: Move default CONFIG_SYS_PROMPT_HUSH_PS2 to hush.c
Exactly one board has defined CONFIG_SYS_PROMPT_HUSH_PS2 to a value
different than "> " which is vision2.  I have Cc'd the maintainer here
as I strongly suspect this is a bug rather than intentional behavior.

bb60db634c nios2 - adjust gbl data off to account for bd_info
* 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.

31a4f1e5b6 board configs: drop NET_MULTI references
Now that none of the core checks CONFIG_NET_MULTI, there's not much point
in boards defining it.  So scrub all references to it.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
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.

1e8e9bad2d nios2: add gpio support to nios2-generic board
This patch adds gpio support of Altera PIO component to the
nios2-generic board. Though it drives only gpio_led at the
moment, it supports bidirectional port to control bit-banging
I2C, NAND flash busy status or button switches, etc.

8cbb0ddd7e nios2: add nios2-generic board
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.
