So to summarize, we need u-boot to initialize the PCIe controller, in
order for Linux to further take it over.

What u-boot versions/releases do provide this initialization?

Only FSL U-Boots so far (i.e. community u-boot + fsl patches).

Could you be more specific?

I would like to test your Linux kernel patch for 83xx/PCIe mainlining.


What version (and what patches) of u-boot do both initialize pcie
*and* work with recent Linux kernels?

I am aware of the latest MPC8315E BSP (~2008-06), bitshrine.org/gpp/,
the 83xx git tree at denx, and master git.

The first works with 2.6.24, but not with 2.6.25+
The patches at bitshrine are not newer than that.
The tree's are not FSL, or is this the FSL U-Boot you mean?

I know the u-boot with the board works, but it's incompatible with
recent Linux kernels.

We should fix that (if possible).

I was told "just to upgrade u-boot", not what the actual problem was,
although I would like to learn that.

Basically, this means I am unable to ship a bootloader now, supporting
2.6.24.7 now and 2.6.28 later.
