 * $Modtime:   Nov 12 2004 22:11:14  $
 * $Log:   //mtkvs01/vmdata/flash_tool/archives/DA/SRC/flash_drv_AM29PDL128G.c-arc  $
 * 
 *    Rev 1.1   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.
