/***************************************************************************
* File Name : bcm63xx_led.c
*
* Description:
*
* This file contains bcm963xx board led control API functions.
*
* To use it, do the following
*
* 1). define in the board.c the following led mappping (this is for 6345GW board):
* const LED_MAP_PAIR cLedMapping45GW[] =
* { // led name Initial state physical pin (ledMask)
* {kLedUsb, kLedStateOff, GPIO_LED_PIN_7},
* {kLedAdsl, kLedStateOff, GPIO_LED_PIN_8},
* {kLedPPP, kLedStateOff, GPIO_LED_PIN_9}, // PPP and WanData share PIN_9
* {kLedWanData, kLedStateOff, GPIO_LED_PIN_9},
* {kLedWireless, kLedStateOff, GPIO_LED_PIN_10},
* {kLedEnd, kLedStateOff, 0 } // NOTE: kLedEnd has to be at the end.
*
* 2). };To initialize led API and initial state of the leds, call the following function with the mapping
* pointer from the above struct
*
* boardLedInit((PLED_MAP_PAIR) &cLedMapping45R);
*
* 3). Sample call for kernel mode:
*
* kerSysLedCtrl(kLedAdsl, kLedStateBlinkOnce); // kLedxxx defines in board.h
*
* 4). Sample call for user mode
*
* sysLedCtrl(kLedAdsl, kLedStateBlinkOnce); // kLedxxx defines in board_api.h
*

The code is intended to decompress kernel, being compressed using lzma utility
build using 7zip LZMA SDK. This utility is located in the LZMA_Alone directory
decompressor code expects that your .trx file consist of three partitions:
1) decompressor itself (this is gziped code which pmon/cfe will extract and run
on boot-up instead of real kernel)
2) LZMA compressed kernel (both streamed and regular modes are supported now)
3) Root filesystem
Please be sure to apply the following patch for use this new trx layout (it will
allow using both new and old trx files for root filesystem lookup code)
