Using 2_4_devel to build a kernel for the 8240

Using 2_4_devel to build a kernel for the 8240

[Stephen Noftall]

Hello;

I am using the latest bitkeeper PPC 2_4_devel kernel, and want to configure it
for the 8240.

When I run menuconfig, I can see "Sandpoint X3" and "8260" selections, but no
8240 specific selections.

What options should I select to enable 8240 support? I am guessing "Sandpoint
X3", is this right? The board is a custom 8240, with Ethernet and SCSI PCI
chipsets, but no serial or ISA components. We have previously gotten a 2.3.16
kernel to work on it.

Thanks for any feedback.

No.  "Sandpoint" is a platform, not a processor.  You select the processor from
inside "Platform support"/"Processor Type".  Since the 8240 is essentially a 603
core with a 107 bridge, select "6xx/7xx/74xx/8260" for your processory type.

You probably want to make a new "Machine Type" for your board/platform and select
it.  Look in arch/ppc/platforms and arch/ppc/config.in for lots of examples.

The Processor Type option text for CONFIG_6xx is wrong.  It should say
82xx instead of 8260.  Select 6xx/7xx/74xx/8260 for now since you
have a "classic PPC" core.

Sandpoint is a board.  It does not "enable" 8240 support.  An 8240 is
more or less a 603e + MPC10x bridge for software purposes.  Add
an entry for your custom board and use mpc10x_common.c like other
examples in 2_4_devel.
