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. http://www.mail-archive.com/u-boot-users@lists.sourceforge.net/msg06551.html Basically, this means I am unable to ship a bootloader now, supporting 2.6.24.7 now and 2.6.28 later.
