These patches add support for A4M072 MPC5200-based board.
The first patch adds new board with support for all devices except for
7-segment LED display.
We've decided to use 'display' command to manipulate the LED display
so the second patch adds very simple generic interface to use such
devices and moves hw-specific realization to drivers/misc/pdsp188x.c
The third patch adds 7-segment LED display support.
And the fourth file adds support for showing boot progress codes on
LED display (we can't display them directly so we use a mapping).
Regards, Ilya.

This patch provides support for the A4M072 board with the following features:
UART
NOR flash
FEC Ethernet
External SRAM
I2C EEPROM
CompactFlash cards on IDE/ATA port
USB Host
PCI initialization
The 7-segment LED indicator is not yet supported.

To: u-boot
Split the display command into generic interface and hardware-specific
realization for PDSP188x LED display found on hmi1001 and manroland
boards. Simple interface for LED displays is defined in
include/led-display.h and described in doc/README.LED_display.
Driver-specific implementation was moved into drivers/misc/pdsp188x.c
file (enabled with CONFIG_PDSP188x set).

+LED display internal API
+=======================================
+
+This README describes the LED display API.
+
+The API is defined by the include file include/led-display.h
+
+The first step in to define CONFIG_CMD_DISPLAY in the board config file.
+Then you need to provide the following functions to access LED display:
+
+void display_set(int cmd);
+
+This function should control the state of the LED display. Argument is
+an ORed combination of the following values:
+ DISPLAY_CLEAR -- clear the display
+ DISPLAY_HOME -- set the position to the beginning of display
+ DISPLAY_MARK -- enable mark (decimal point), if implemented
+
+int display_putc(char c);
+
+This function should display it's parameter on the LED display in the
+current position. Returns the displayed character on success or -1 in
+case of failure.
+
+With this functions defined 'display' command will display it's
+arguments on the LED display (or clear the display if called without
+arguments).

To: u-boot
This patch adds support for LED display on a4m072 board. Hardware is
capable of displaying only one symbol at any time. We support displaying
two symbols in software (via blinking).

* [U-Boot] [PATCH 4/4] a4m072: support for SHOW_BOOT_PROGRESS feature using LED display

To: u-boot
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).
