* $Log: //mtkvs01/vmdata/flash_tool/archives/DA/SRC/flash_drv_RENESAS.c-arc $
*
* Rev 1.4 Jun 15 2005 12:23:06 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 30 2004 17:20:04 mtk00539
* [FIX BUG] DON'T use fixed 128 WORDs Page-Program method.
* Because when length_in_word is less than 128, Page-Program will fail!
* Therefore, we have to use another program method.
* First, load variant length data to Page-Buffer, then flush Page-Buffer to flash.
* 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 Oct 29 2004 11:46:46 mtk00539
* 1. [DA][BUG FIX] Read CFI boot sector flag to determine AM49DL3208GT and S71PL032J, since both flashes have the same id, but different layout.
* 2. [DA][BUG FIX] Fix INTEL and RENESAS status checking flow.
* 3. [DA][Enhance] Dump more logs in TEST_ExtSRAM().
* 4. [DA][New] Support new flashes
* [SAMSUNG] K5J6316CTM
* [TOSHIBA] TH50VPF5682CDSB
* [TOSHIBA] TH50VPF5683CDSB
* [ISSI] IS75V16F128GS32
* [RENESAS] M6MGT64BM34CDG
* [ST] M30L0T7000T0, M36L0T7050T0
* [ST] M30L0T7000B0, M36L0T7050B0
* [SHARP] LRS1862
* [SHARP] LRS1806A
* [AMD] AM49DL3208GT
* [SPANSION] S29PL032J, S71PL032J
* Resolution for 92: [BROM_DLL v2.4.1006][BUG FIX] Fix AM49DL3208GT & S71PL032J download fail problem and some enhancement.
