[U-Boot] [PATCH] Powerpc/QE: Add QE support for T1040

Zhao Qiang B45475 at freescale.com
Fri Jan 24 10:05:49 CET 2014


T1040 has QE-related addresses different from other boards,
modify those addresses value with macro CONFIG_PPC_T1040
and CONFIG_T1040QDS.
Add function qe_board_setup to mux the bus to tdm or uart
according to hwconfig.
