After gadget reinitializaton (after tftp has been done once)
packet_received may become equal to 1 due to nuking OUT_EP
while disabling it in eth_reset_config.

rx_submit called from usb_eth_init queues rx_req first time.
But the first call of usb_eth_recv from NetLoop queues rx_req
again due to packet_received = 1.

The following flow shows the path of functions calls when
this happens:

 net/net.c:NetLoop
 |
 +-net/eth.c:eth_init
 |   ether.c:usb_eth_init
 |   |
 |   +-udc_driver:usb_gadget_handle_interrupts

 |   |             udc_driver:nuke
 |   |               ether.c:rx_complete
 |   |                 ether.c: packet_received = 1;
 |   |
 |   +-ether.c:rx_submit

     ether.c:usb_eth_recv

     +-ether.c: if (packet_received) { ...

Remove and fix needless and destructive operations with tx/rx_req.

1) 'req' in rx_complete is always not NULL and always equals to rx_req
2) Free allocated tx_req if rx_req allocation has failed
3) Do not zero out tx/rx_req in usb_eth_init, leave this for
eth_reset_config which will be called at the next use of usb0
4) Additional check in usb_eth_recv is not required

Adds support for the ARM quad-core Cortex-A9 processor

This system includes a motherboard(Versatile Express), daughterboard
(Coretile), and SOC(Cortex-A9 quad core).  The serial port, ethernet,
and flash systems work with these additions.  The naming convention
is:
   SOC -> CortexA9 quad core = ca9x4
   daughterboard -> Coretile = ct
   motherboard -> Versatile Express = vxp
This gives ca9x4_ct_vxp.c as the board support file.

Signed-off-by: NPrafulla Wadaskar <prafulla@marvell.com>

It is observed that, in most of the board configs the code is being
duplicated, also for any common change all board files needs update
This issue was under discussion from long on mailing list and we
converge on introducing common config file.

With this patch-
1. Total Kirkwood specific configuration code is reduced by 210 lines
2. All common configuration can be shared by multiple boards
3. Easy to manage common updates like ARM relocation changes

mv-common.h file is added to include/configs/
It contains all common configuration supported for all Kirkwood boards
The respective board configs are updated for its usage

Build tested for guruplug, mv88f6281gtw_ge, openrd_base,
rd6281a and sheevaplug
Binary execution tested for sheevaplug

Todo:
1. Other custom Kirkwood boards to be synced
2. The support to be extended for Orion5X based boards

dram_init function is moved to dram.c and relevant code from all

If any board needs specific dram init handling than standard one,
then, a macro CONFIG_SYS_BOARD_DRAM_INIT should be defined in
board config header file and the dram_init function can be put
in board specific source file

This patch does 2 things:
 - Fix the argument number assigned to the vdw (VME data width) value.
   Previously, a nonexistent 7th arument was read as the vdw variable.

 - Reduce the size of the argument array for the tsi148 command from
   8 to 7.  The tsi148 command itself is argument index 0, and the
   maximum number arguments passed to the command is 6, making a total
   of 7 for the array.

Using -fno-toplevel-reorder causes gcc to not reorder functions.  This
ensures that an application's entry point will be the first function in
the application's source file.

This change, along with commit 620bbba5
should cause a standalone application's entry point to be at the base of
the compiled binary.  Previously, the entry point could change depending
on gcc version and flags.

Note -fno-toplevel-reorder is only available in gcc version 4.2 or
greater.

This patch adds support for displaying boot progress codes on a4m072 board
using LED display. As we can display only one symbol at any time on the hardware
(two symbols with blinking) we can't display progress codes directly and have
to map them to 2-symbol codes.
We use the following mapping on the a4m972 board:
 [1, 8] U [100, 108]					-> 5
 [-9, -1] U [-101, -100] U [-113, -103]			-> -5
 [9, 14] U [120, 123] U [125, 129]			-> 8
 [-13, -10] U [-122, -120] U [-127, -124] U {-129}	-> -8
 {15}							-> 9
 [-32, -30]						-> -A
 [-40, -35] U [-51, -42] U [-58, -53] U
		[-83, -80] U {-64, -130, -140, -150}	-> -B

Other progress code are ignored. One symbol codes are displayed steady while
two-symbol codes are displayed using blinking. Boot progress codes are
displayed with decimal got unset (as opposed to 'display' command output).
