** Resending with the right lists ** after talking at devconf with David Cantrell about the best way to support setting up uboot on arm devices in anaconda, the best approach going forward is pretty clear, ill get to it in a bit first i want to describe things as I see them. Unified kernel while solving many issues introduces some. platform detection was kinda simple with separate kernels. unified kernel means that while we dont need to worry about having the right kernel, we do need to worry about loading the right dtb. platform detection is also needed to know where in ram we should load the kernel and offsets for initramfs and dtb to be loaded. anaconda can tell us the filesystem and device that we are installing to, but depending on the exact way support is done in uboot we may need to put in different values, SCSI vs SATA vs USB etc we also need to ensure we use the right dtb file. for instance a pandaboard ES can use a pandaboard dtb but will be 1ghz vs the 1.2ghz its capable of. some systems like the highbank ones have the dtb in their uboot. while others need to load an external file. so as i see it we need a library that anaconda can import and use to work out the right values for the system we are installing to. probably the library should write out the uboot template and run mkconfig on it. we could then reuse the library in a tool to say setup a boot sdcard to run the installer on a system. we have an issue where it is really not possible to make the equivilent of a boot.iso that will be bootable everywhere. I think we should take this up to the cross distro list at linaro and ideally have the distros work on a database at the least of platforms and the values and types needed. if not the whole library that can be used in different places to set things up. this is only needed for 32 bit arm, 64 bit will have UEFI, ACPI and grub2. potentially we also want to consider if we can implement http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec since we need to implement something anyway.
