*
* Rev 1.5 Oct 19 2005 14:45:16 mtk00539
* 1. [BROM_DLL&DA][New] New H/W devices detection architecture including NOR, NAND, SRAM and DRAM detection.
* 2. [BROM_DLL&DA][New] DA partial download technic, that overcomes DA size exceeds MT6205B internal SRAM (32KB).
* 3. [BROM_DLL&DA][New] Format verification option, each byte should be 0xFF after erasure.
* 4. [BROM_DLL&DA][New] DA validation to ensure invalid binary could not be loaded.
* 5. [BROM_DLL&DA][New] Support NFB download.
* 6. [BROM_DLL&DA][New] Support NAND flash format with 3 method, NORMAL, FORCEDLY ERASE and MARK AS BAD BLOCK.
* 7. [BROM_DLL&DA][New] Support NAND flash read back with 4 methods, PAGE+ECC, PAGE ONLY, SPARE ONLY and PAGE+SPARE.
* Resolution for 140: [BROM_DLL v2.7.1008][New] Support NFB download and many new features.
*
* Rev 1.4 Jun 15 2005 12:41:52 mtk00539
* 1. [DA][New] Support new flash devices TV0057A002AABD and TV0057A002AABD.
* 2. [DA][New] Support RENESAS flash with F-WP#(LOW).
* Resolution for 118: [BROM_DLL v2.4.1013][New] Support RENESAS flash with F-WP#(LOW).
*
* Rev 1.3 Nov 25 2004 09:49:22 mtk00539
* [DA][Enhance] In order to speed-up the progress, only verify one time after erase.
* Resolution for 99: [BROM_DLL v2.4.1008][New] Support INTEL family flash Buffered-Program method.
*
* Rev 1.2 Nov 22 2004 12:25:36 mtk00539
* 1. [DA][BUG FIX] Add data verification in status polling during erase or program operation.
* 2. [DA][BUG FIX] Fix two dies flash detection fail in INTEL_CheckDevID().
* 3. [DA][Change Behavior] When RX_BUFFER_FULL occurs, flush data queued in UART ring buffer til data is less than 512KB.
* 4. [DA][New] Support Buffered-Program method for INTEL family flashes.
* 5. [DA][New] Support new flashes [SHARP]LRS1828C and [RENESAS]M6MGB64BM34CDG.
* Resolution for 99: [BROM_DLL v2.4.1008][New] Support INTEL family flash Buffered-Program method.
*
* Rev 1.1 Aug 03 2004 10:33:06 mtk00539
* 1. [DA][BUG FIX] Invoke Board_Schematic()(old name is HW_Init()) before FUTL_CheckDevice(). Because FUTL_CheckDevice() must know the absolute address for each bank.
* 2. [DA][New] Add 12 new flash devices support
* [SAMSUNG]K5A3280YT,
* [TOSHIBA]TH50VPF6782AASB,
* [TOSHIBA]TH50VPF6783AASB,
* [TOSHIBA]TV00578002AABD,

* [INTEL]INTEL_28F640W30_B,
* [SPANSION]AM49PDL127BH,
* [SPANSION]AM49PDL129BH,
* [RENESAS]M6MGD13BW66CDG,
* [Winbond]W19B322TM,
* [Winbond]W19B323TM,
* 3. [DA][New] Readback check after WORD program is done, so that DA won't have to keep the chksum.
* 4. [DA][New] Auto-detect baseband chip type.
* 5. [DA][New] Auto-detect external SRAM size.
* 6. [DA][New] Merge MT6205B, MT6218B and MT6219 to an all-in-one DA.
* 7. [DA][New] Merge flash stress test module.
* 8. [DA][New] Modify makefile to build ARM or THUMB code.
* 9. [DA][New] Construct a customization kit for customers to add new flash or SOC checking algorithm by themselves.
* 10. [DA][Enhance] Split out AM29PDL128G function to improve the performance of general AMD callback functions.
* 11. [DA][Enhance] Enhance RX_BUFF_FULL behavior to prevent always retry two times.
* Resolution for 83: [BROM_DLL v2.4.1002] Merge all the DAs into all-in-one DA and fix many bugs and enhancement.
*
* Rev 1.0 Jul 19 2004 01:44:40 mtk00539
* Initial revision.
