You have two options. 

1) Use ecosconfig. It ignores the hardware property and allows you to
   add/remove anything.
2) Making this change to your ecos.db:

target at91sam7xek {
        alias { "Atmel AT91SAM7XEK evaluation board" at91_at91sam7xek }
        packages { CYGPKG_HAL_ARM
                   CYGPKG_HAL_ARM_AT91
                   CYGPKG_HAL_ARM_AT91SAM7
                   CYGPKG_HAL_ARM_AT91SAM7XEK
                   CYGPKG_IO_SERIAL_ARM_AT91
                   CYGPKG_DEVS_FLASH_AT91
                   CYGPKG_IO_SPI
                   CYGPKG_DEVS_SPI_ARM_AT91
                   CYGPKG_DEVICES_WATCHDOG_ARM_AT91WDTC
                   CYGPKG_IO_USB
                   CYGPKG_IO_USB_SLAVE
                   CYGPKG_DEVS_USB_AT91
                   CYGPKG_DEVS_ETH_PHY
                   CYGPKG_DEVS_ETH_ARM_AT91
                   CYGPKG_
        }
        description "
        The at91sam7xek target provides the packages needed to run eCos on an 
        Atmel AT91SAM7X-EK evaluation board."
}
