Subject: [patch 16/43] ppc32: ppc_sys fixes for 8xx and 82xx
Date: Fri, 28 Oct 2005 17:46:28 -0700 [thread overview]
Message-ID: <200510290046.j9T0kxpS030035@shell0.pdx.osdl.net> (raw)
From: Vitaly Bordug <vbordug@ru.mvista.com>
This patch fixes a numbers of issues regarding to that both 8xx and 82xx
began to use ppc_sys model:
- Platform is now identified by default deviceless SOC, if no
BOARD_CHIP_NAME is specified in the bard-specific header. For the list
of supported names refer to (arch/ppc/syslib/) mpc8xx_sys.c and
mpc82xx_sys.c for 8xx and 82xx respectively.
- Fixed a bug in identification by name - if the name was not found, it
returned -1 instead of default deviceless ppc_spec.
- fixed devices amount in the 8xx platform system descriptions
