| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use 64-bit math when finding a block of ram to hold the kernel. This fixes a problem on 32-bit systems which have ram occupying the end of the physical address space -- for example, a block of ram at 0x80000000 with a size of 0x80000000 was overflowing 32 bit math and ending up with a calculated size of zero. Use 64-bit math when processing the lists of physical and excluded memory to generate the phys_avail and dump_avail arrays. Work around problems that happen when there is ram at the end of the physical address space. Cast pointer through uintptr_t on the way to uint64_t to squelch a warning. Reword the comment to better describe what I found while researching the problem that led to this temporary workaround (and also so I can properly cite the PR in the commit this time). Cast using uintfptr_t and eliminate the cast to uint64_t which is uneeded because rounding down cannot increase the number of bits needed to express the result. Go back to using uintptr_t, because code that actually compiles is infinitely less buggy than code that is theoretically correct in some alternate universe. PR: 201614

| | | | | | | Fix the error checking for the ubenv command. This moves the check for an empty ldvar (which amounts to the varname string starting with '=') into the if block that manipulates ldvar, which avoids later referencing ldvar when it was never initialized.

| | | | | | | | | | Print more detailed info about the disk and partition chosen for booting. No behavioral changes, just cosmetics. Remove stray unescaped `%` in `Booting from ...` informational message. Enhance the "ubenv import" command to allow importing a u-boot env var directly into a loader (and thus kernel) env var.

| | | | | | | | | | | | | | | | | Add support for booting relocatable kernels on PowerPC. Add code to support loading relocatable kernels at offsets that are not zero. Move ubldr text section to the start of the output file, so that when you create a stripped .bin file from it the entry point is the first byte of the file. (Will allow "load $addr $file ; go $addr" in u-boot.) Create a relocatable instance of ubldr for ARM (ubldr.bin). Re-link ubldr when any of its libraries change. An ARM kernel can be loaded at any 2MB boundary, make ubldr aware of that.

MFC 273934: Start to allow platforms other than U-Boot to use the FDT code in loader by moving U-Boot specific code from libfdt.a to a new libuboot_fdt.a.

* MFC r263052, r263124, r263265, r263267... Enhance loaderdev env var.ian2014-04-295-95/+336
| | | | | | | | | | | | | | | | | Enhance the mechanism that lets you configure the ubldr boot device by setting the u-boot environment variable loaderdev=. It used to accept only 'disk' or 'net'. Now it allows specification of unit, slice, and partition as well. In addition to the generic 'disk' it also accepts specific storage device types such as 'mmc' or 'sata'. If there isn't a loaderdev env var, the historical behavior is maintained. It will use the first storage device it finds, or a network device if no working storage device exists. 99% of the work on this was done by Patrick Kelsey, but I made some changes, so if anything goes wrong, blame me. (Indeed, the 3 followup commits fixed things I got wrong on the first.)

| | | | | | | | | | | | | Prevent fdt data loaded from a file from overwriting the kernel environment, by having uboot_autoload() do the fdt setup (which may load a file) rather than waiting until we're actually in the process of launching the kernel. As part of making this happen... - Define LOADER_FDT_SUPPORT on the uboot/lib compile command line when MK_FDT is set. - Make fdt_setup_fdtb() public. - Declare public fdt_whatever() functions in a header instead of using scattered extern decls in .c files.

* - Implement "fdt mres" sub-command that prints reserved memory regionsgonzo2012-11-301-4/+15
| | | | | | | | | | | | | | | | | | | - Add "fdt addr" subcommand that lets you specify preloaded blob address - Do not pre-initialize blob for "fdt addr" - Do not try to load dtb every time fdt subcommand is issued, do it only once - Change the way DTB is passed to kernel. With introduction of "fdt addr" actual blob address can be not virtual but physical or reside in area higher then 64Mb. ubldr should create copy of it in kernel area and pass pointer to this newly allocated buffer which is guaranteed to work in kernel after switching on MMU. - Convert memreserv FDT info to "memreserv" property of root node FDT uses /memreserve/ data to notify OS about reserved memory areas. Technically it's not real property, it's just data blob, sequence of <start, size> pairs where both start and size are 64-bit integers. It doesn't fit nicely with OF API we use in kernel, so in order to unify thing ubldr converts this data to "memreserve" property using the same format for addresses and sizes as /memory node.

* Almost each time when loader opens a file, this leads to callingae2012-09-291-0/+1
| | | | | | | | | | | | | | | | | | disk_open(). Very often this is called several times for one file. This leads to reading partition table metadata for each call. To reduce the number of disk I/O we have a simple block cache, but it is very dumb and more than half of I/O operations related to reading metadata, misses this cache. Introduce new cache layer to resolve this problem. It is independent and doesn't need initialization like bcache, and will work by default for all loaders which use the new DISK API. A successful disk_open() call to each new disk or partition produces new entry in the cache. Even more, when disk was already open, now opening of any nested partitions does not require reading top level partition table. So, if without this cache, partition table metadata was read around 20-50 times during boot, now it reads only once. This affects the booting from GPT and MBR from the UFS.

* Determine kernel load address dynamically from u-boot memory map.kientzle2012-05-203-10/+46
| | | | | | | | | | | The generic ELF loading code maps the kernel into low memory by subtracting KERN_BASE. So the copyin/copyout/readin functions are always called with low addresses. This code finds the largest DRAM block from the U-Boot memory map and adds that base to the addresses. In particular, this fixes ubldr on AM3358, which has DRAM mapped to 0x80000000 at power-on.

* Access the device tree blob via copyin/copyout.kientzle2012-05-171-2/+2
| | | | | | | | | | | | | The code previously assumed that copyin/copyout did no address translation and that the device tree blob could be manipulated in-place (with only a few adjustments for the ELF loader offset). This isn't possible on all platforms, so the revised code uses copyout() to copy the device tree blob into a heap-allocated buffer and then updates the device tree with copyout(). This isn't ideal, since it bloats the loader memory usage, but seems the only feasible approach (short of rewriting all of the fdt manipulation routines).
