Hello list,
inside the automatic U-Boot patch tracking system a new ticket [DNX#2006040142000642] was created:
<snip>
Seven patches on the way which add support for using the Flat device tree in u-boot to pass device initialization information to Linux, which is used for 85xx support in the arch/powerpc tree.
These patches build on the previous patches, which add 8540 ADS support (without PCI).
In addition, as part of the update, PCI initialization has been moved fully into u-boot, so all PCI busses are now scanned and configured.
Here's the index of the patches:
1: Fix prefetch disabling code in drivers/pci_auto.c so it sets the memory limit to 0 (instead of 0x1000) 2: Adds PCI-X #defines for PCI-X initialization 3: Fixes a bug in the fdt setup code for 85xx, where memory size was not
updated based on reality 4: Adds support for initializing the second PCI bus 5: Adds PCI and I2C fdt support for 8540ADS 6: Adds PCI and I2C fdt support for 85xx CDS 7: Changes the 8540 ADS PCI speed back to 66 MHz, and adds warnings and comments to the effect that PCI-X will not work unless it's running at 66 MHz.
