[U-Boot] [PATCH v4 2/2] Powerpc/QE: Add QE support for T1040
The u-qe of T1040 has addresses different from qe, modify those addresses value for both u-qe and qe.
Add function qe_board_setup to mux the bus to tdm or uart according to hwconfig.
Signed-off-by: Zhao Qiang B45475@freescale.com --- Changes for v2: - modify CONFIG_SYS_QE_FMAN_FW_ADDR to CONFIG_SYS_FMAN_FW_ADDR and CONFIG_SYS_QE_FW_ADDR Changes for v3: - use CONFIG_U_QE instead of CONFIG_PPC_T1040 Changes for v4: - ifdef CONFIG_U_QE, include "../../../../drivers/qe/qe.h"
