1. Fixed the routine distinguish between Smart Media board and MMC
board using HW CPLD version.
- Boot/Startup program check CPLD bit for distinguishing between
Smart Media board and MMC board.
But the routine has check error. So we fixed it correctly.
From CPLD V09 of OS500 MCP2 board, it must be used Boot V1.07
and Startup V1.08.
(Current Smart Media MCP2 Board use CPLD01~03 and MMC MCP2
Board use CPLD05(for Beta test),08. And MMC MCP2 Board will use
CPLD09 in the future)
2, If reset button was pressed during booting in MMC card, system
occasionally doesn't boot normally.
- If reset button was pressed when the data transmission wasn't finished,
initializing MMC card isn't working normally.
So we added routine to stop previous data transmission before initializing
MMC card.
