How to build u-boot for cycloneII board?

Hi posix6973,

> *** Warning - bad CRC, using default environment

Your environment has a bad CRC. Until you save the environment to non-volatile memory u-boot will

detect an invalid environment and use the default environment (which is defined at compile time). For

the EP1C20, the environment is stored at 0x0004_0000 (flash: CFG_ENV_ADDR).

Please read the top-level README ... it contains alot of useful information. You can simply search for

" _ENV_" to review environment information.

Remove the SMC driver macros (e.g. CONFIG_SMC91111_BASE) and define CONFIG_DRIVER_DM9000

... and other CONFIG_DM9000_xxx macros as needed.
