[U-Boot] how to disable pci bursts
by Lozano, Jose 07 Jul '09

07 Jul '09

Hi: I am using a MPC8548 cpu running the 2.6.29 version of the linux kernel. It seems that the cpu is generating pci bursts under the same conditions when a previous version of the kernel (namely 2.6.23) is not. Does anybody know how to disable pci bursts in this cpu? I am interfacing a device that doesn't support PCI bursts. Thanks for the help. Jose Lozano

[U-Boot] [PATCH] UBI: Fix build problem noticed on Apollon (arm/testing repo)
by Stefan Roese 07 Jul '09

07 Jul '09

This patch fixes a build problem noticed on Apollon by using mtd_dev_by_eb() instead of "/" as done in the Linux UBI version. So this brings the U-Boot UBI version more in sync with the Linux version again.
