* fix copyright messages * remove all HAVE_HIGH_TABLES and HAVE_LOW_TABLES preprocessor hackery and instead use high_tables_base to find out if high tables should be used.

2009-04-30Refactor copy_and_run so that it uses a single code base instead ofPatrick Georgi
3 (with one of them way too much assembler code). On the way, I had to make some changes to the way the code is built, which is an effort I want to expand over time. Right now, large portions of the in-ROM part of coreboot is compiled as a single file, with lots of .c files including other .c files. That has its justification for pre-raminit code, but it also affects lots of post-raminit code (memcpy doesn't really make sense before raminit, or at least CAR) The coreboot_apc code (AMD boards) gained some .c includes because I don't know that part of the code enough to really rework it and only have limited possibilities to test it. The includes should give an identical situation for this part of the code. This change was posted as set of 6 patches to the list, but they were mostly split for review purposes, hence commit them all at once. They can still be backed up using the patch files, if necessary.

2009-04-03I thought that romfs infrastructure is done now, but there were somePatrick Georgi
issues (see buildbot). The romfs image was always built, and sometimes broke (because of the different image layouts) for buildrom images. After the patch, these issues are avoided by not adding payloads to the romfs image (they wouldn't be read anyway). Both workarounds (in buildrom code for romfs and vice-versa) aren't very pretty, but that's what our buildsystem requires. As I had to create a "communication channel" (via the romfs-support files), I took the chance to also use it for compression information, so if you configure lzma support, you'll get lzma compressed payloads in romfs.

2009-04-03the attached patch is the last infrastructure change necessary forPatrick Georgi
romfs. Everything else to make a target romfs aware happens in the targets. What the patch does: 1. missing romfs.h include 2. special handling while creating coreboot.rom While the romfs code path in the makefile doesn't actually use the file, it's possible that the build of coreboot.rom fails in a romfs setup, because the individual buildrom image is too small to host both coreboot and payloads (as the payloads aren't supposed to be there). Thus, a special case to replace the payload with /dev/null in case of a romfs build. There would be cleaner ways, but they're not easily encoded in the Config.lb format. 3. config.g is changed to create rules for a romfs build Targets should still build (they do for me) Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4049 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

The bug is in src/arch/i386/boot/boot.c. The inline assembly in jmp_to_elf_entry uses the "g" flag to pass in parameters. However, "g" allows gcc to use stack relative addressing of parameters.

2009-03-17This patch adds "high coreboot table support" to coreboot version 2.Stefan Reinauer
Some bootloaders seem to overwrite memory starting at 0x600, thus destroying the coreboot table integrity, rendering the table useless. By moving the table to the high tables area (if it's activated), this problem is fixed. In order to move the table, a 40 bytes mini coreboot table with a single sub table is placed at 0x500/0x530 that points to the real coreboot table. This is comparable to the ACPI RSDT or the MP floating table. This patch also adds "table forward" support to flashrom and nvramtool.

2008-03-29Now coreboot performs IRQ routing for some boards.Nikolay Petukhov
You can see this by executing commands like this: grep -r pci_assign_irqs coreboot/src/* This basically AMD/LX based boards: pcengines/alix1c, digitallogic/msm800sev, artecgroup/dbe61, amd/norwich, amd/db800. Also for AMD/GX1 based boards need a patch [http://www.pengutronix.de/software/ptxdist/temporary-src/references/geode-5530.patch] for the right IRQ setup. AMD/GX1 based boards is: advantech/pcm-5820, asi/mb_5blmp, axus/tc320, bcom/winnet100, eaglelion/5bcm, iei/nova4899r, iei/juki-511p. I have two ideas. 1. Delete duplicate code from AMD/LX based boards. 2. Add IRQ routing for AMD/GX1 boards in coreboot. The pirq.patch for IRQ routing logically consist from of two parts: First part of pirq.patch independent from type chipsets and assign IRQ for ever PCI device. It part based on AMD/LX write_pirq_routing_table() function. Second part of pirq.patch depends of type chipset and set PIRQx lines in interrupt router. This part supports only CS5530/5536 interrupt routers. IRQ routing functionality is included through PIRQ_ROUTE in Config.lb. Tested on iei/juki-511p(cs5530a), iei/pcisa-lx(cs5536) and also on TeleVideo TC7020, see http://www.coreboot.org/pipermail/coreboot/2007-December/027973.html.

Linuxbios boots an Opteron motherboard with 1GB memory. Linuxbios directly loads a recent linux kernel. The memory layout is like this: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 0000000000000e18 (reserved) BIOS-e820: 0000000000000e18 - 00000000000a0000 (usable) BIOS-e820: 00000000000c0000 - 00000000000f0000 (usable) BIOS-e820: 00000000000f0000 - 00000000000f0400 (reserved) BIOS-e820: 00000000000f0400 - 0000000040000000 (usable) The f0000-f0400 region contains IRQ and ACPI tables. At some point the kernel builds a resource table containing all physical address ranges and type of hardware the addresses are mapped to. The table is accessible via /proc/iomem: # cat /proc/iomem 00000000-00000e17 : reserved 00000e18-0009ffff : System RAM 000a0000-000bffff : Video RAM area 000c0000-000cbfff : Video ROM 000f0000-000fffff : System ROM e0000000-efffffff : PCI Bus #03 e0000000-efffffff : 0000:03:00.0 f0000000-f3ffffff : GART f4000000-f60fffff : PCI Bus #03 f4000000-f4ffffff : 0000:03:00.0 f5000000-f5ffffff : 0000:03:00.0 f6000000-f601ffff : 0000:03:00.0 f6100000-f6100fff : 0000:00:01.0 f6101000-f6101fff : 0000:00:02.0 f6101000-f6101fff : ohci_hcd f6102000-f6102fff : 0000:00:04.0 f6103000-f6103fff : 0000:00:07.0 f6103000-f6103fff : sata_nv f6104000-f6104fff : 0000:00:08.0 f6104000-f6104fff : sata_nv f6105000-f6105fff : 0000:00:0a.0 f6106000-f61060ff : 0000:00:02.1 f6200000-f620ffff : 0000:40:01.0 As you can see, the 00000000000f0400-0000000040000000 region is not listed. It is not listed because the kernel unconditionally adds "000f0000-000fffff : System ROM" first (look for "request_resource(&iomem_resource, &system_rom_resource)"), and then the attempt to add f0400-40000000 range fails because of overlapping. The kernel does not care that the range is not listed there. Kexec does. It uses the /proc/iomem file to instruct the kexec system call how to place the segments of a new kernel in the physical memory. Kexec fails to start a new kernel because it cannot locate enough physical memory. This must be fixed either in linux or linuxbios. Assuming that linuxbios is to be fixed, I cooked a patch which provides this memory layout: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 0000000000000e18 (reserved) BIOS-e820: 0000000000000e18 - 00000000000a0000 (usable) BIOS-e820: 00000000000c0000 - 00000000000f0000 (usable) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 0000000040000000 (usable) The /proc/iomem contains: # cat /proc/iomem 00000000-00000e17 : reserved 00000e18-0009ffff : System RAM 000a0000-000bffff : Video RAM area 000c0000-000cbfff : Video ROM 000f0000-000fffff : System ROM 00100000-3fffffff : System RAM 00100000-00203c61 : Kernel code 00203c62-00248c3f : Kernel data e0000000-efffffff : PCI Bus #03 e0000000-efffffff : 0000:03:00.0 f0000000-f3ffffff : GART f4000000-f60fffff : PCI Bus #03 f4000000-f4ffffff : 0000:03:00.0 f5000000-f5ffffff : 0000:03:00.0 f6000000-f601ffff : 0000:03:00.0 f6100000-f6100fff : 0000:00:01.0 f6101000-f6101fff : 0000:00:02.0 f6101000-f6101fff : ohci_hcd f6102000-f6102fff : 0000:00:04.0 f6103000-f6103fff : 0000:00:07.0 f6103000-f6103fff : sata_nv f6104000-f6104fff : 0000:00:08.0 f6104000-f6104fff : sata_nv f6105000-f6105fff : 0000:00:0a.0 f6106000-f61060ff : 0000:00:02.1 f6200000-f620ffff : 0000:40:01.0 Kexec is happier with the patch.
