Subject: [U-Boot-Users] [PATCH] fix system config overwrite @ MPC834x and MPC8313
Date: Mon, 23 Jun 2008 11:40:56 +0200 [thread overview]
Message-ID: <485F6FA8.1080001@matrix-vision.de> (raw)
During 83xx setup the "System I/O configuration register high" gets
overwritten with user defined value if CFG_SICRH is defined.
Regarding to the MPC834x manual (Table 5-28 reve.1) bits 28+29 of SICRH
must keep their reset value regardless of configuration.
On my board (using RGMII) those bits are set after reset - yet it's
unclear where they come from.
The patch keeps both bits on MPC834x and MPC8313.
