[U-Boot-Users] ppcboot on MPC860L

Hi Feiyang,

Huh?  You should really start using U-Boot.  I mean you found the
mailing list, now start using the code ;)

> change, I changed the board/TQM8xx/flash.c  and tqm8xx.c, and some other files.

If you are working on your own port, you should also come up with a
new platform and *not* change files relevant for other *supported*
platforms.  Also I cannot stop repeating myself here on the mailing
list from advising you to use drivers/cfi_flash.c nowadays.

Use current code (top of tree git), use the cfi_flash driver.
