[U-Boot] Burning U-boot on 460EX using BDI3000

It should be possible.

A BDI2000 configuration file flash section looks
something like this:

; =================================================================
[FLASH]
CHIPTYPE    MIRRORX16   ;Flash type: Spansion S29GL256N 32MB
CHIPSIZE    0x2000000   ;The size of one flash chip in bytes
BUSWIDTH    16          ;The width of the flash memory bus in bits
                         ; (8 | 16 | 32 | 64)
;WORKSPACE   0x1000      ;workspace in DDR RAM
FILE        u-boot-1.3.1.bin
FORMAT      BIN 0xfe000000
ERASE       0xfe000000  ;erase sector 0 (128kB sectors)
ERASE       0xfe020000  ;erase sector 1


Make sure to comment out WORKSPACE, and the BDI should
be able to program the board flash without needing DDR
configured.

Cheers,
Dave
