The enclosed patches and attached files add flash support for the Samsung
SNDS100 development board. Specifically, support for the Winbond W29EE011
flash chips.
This adds the Winbond W29EExxx flash driver and flash support for
the Samsung SNDS100 development board to ecos.db.

This fixes the synchronous DRAM initialization for the two
K4S641632D TC1L DRAM chips (16MByte) jumpered to DRAMCON0 at
JP1 (SDRAM position 0). It also includes the patch from
Jonathan Larmour to only include the startup code for the ROM
and ROMRAM versions.
