Subject: [U-Boot] ppc: using d-cache for C stack and as cache at the same time?
Date: Wed, 01 Apr 2009 10:20:53 +0200 [thread overview]
Message-ID: <49D323E5.9080100@tqs.de> (raw)
Hi,
AFAIK, while running from flash, u-boot uses (part of) d-cache on some
platforms for the C stack. I think, it's on MPC83xx and MPC85xx?
Does anybody know, if I can use the remaining part of the d-cache
as normal d-cache, e.g. to generate bursts on the SDRAM interface
while testing the RAM?
Kind regards,
Jens
