[U-Boot] [PATCH v7 2/3] QE/U-QE: Add U-QE support

Zhao Qiang B45475 at freescale.com
Fri Mar 21 09:21:45 CET 2014


Modify code to adapt to both u-qe and qe.

U_QE is a kind of cutted QE.
the differences between U_QE and QE
	1. UCC: U_QE supports 2 UCCs while QE supports up to 8 UCCs.
	2. IMMR: have different immr base addr.
	3. iopin: U_QE doesn't need to config iopin.

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"
Changes for v5:
	- no
Changes for v6:
	- rebase
Changes for v7:
	- split to two patches, the one to support u-qe and the other is to add u-qe to t1040qds
