---------- Forwarded message ---------- From: Mike Hibbett <mhibbett(a)ircona.com> Date: 2014-05-20 14:06 GMT+02:00 Subject: [flashrom] A couple of bugs.. To: "flashrom(a)flashrom.org" <flashrom(a)flashrom.org> I spotted these two in yesterday’s code base. I’m not likely to commit code anytime soon so I will leave it to someone else to pick up if they are interested. src/vendorcode/intel/fsp/baytrail/include/fspplatform.h:78 Duplicate declaration of GetFspReservedMemoryFromGuid src/northbridge/intel/fsp_sandybridge/fsp/chipset_fsp_util.c:92 GetUpdDefaultFromFsp (fsp_ptr, fsp_upd_data);/home/martin/extra/git/coreboot Maybe martin would like to fix that one :o) Mike _______________________________________________ flashrom mailing list flashrom(a)flashrom.org http://www.flashrom.org/mailman/listinfo/flashrom

I certainly like seeing the words 'mortem' and 'EFI' in the same email ;-)

* ron minnich <rminnich(a)gmail.com> [140514 19:22]: > what's an "EFI OS"? An OS that implements the UEFI standard, e.g. TianoCore / edk2 ;) This is under the assumption that every advanced boot loader eventually turns into an operating system. SCNR. Stefan

MMC support in libpayload
by Sean McNeil 20 May '14

20 May '14

Has anyone looked into this or made any effort to add MMC/sdcard support to libpayload? I need to be able to boot from eMMC connected to a PCI sdcard device and think that it would be very useful to have libpayload support. I found comments from Google about booting from eMMC for baytrail and I think they are using a u-boot payload, but I cannot find any effort that corresponds to this. It also looks like u-boot as a payload can only boot 32-bit kernels, so it seems limiting. Sean

I am not sure if this is only for CONFIG_ANY_TOOLCHAIN=y, but builds are not working again for me. This time I don't think it is some addition I am missing: The first problem seems to be that the wrong libgcc.a is found. I think toolchain.inc is missing flags: LIBGCC_FILE_NAME_$(1) = $(wildcard $(shell $(CC_$(2)) $(CFLAGS_$(2)) -print-libgcc-file-name)) Next, it would appear that the smm stage is still using 64-bit code: /usr/bin/ld: Relocatable linking with relocations from format elf32-i386 (build/arch/x86/lib/memcpy.smm.o) to format elf64-x86-64 (build/cpu/x86/smm/smm.o) is not supported Looks like in src/cpu/x86/smm/Makefile.inc the CC_smm is not correct. $(obj)/cpu/x86/smm/smm.o: $$(smm-objs) $(LIBGCC_FILE_NAME_smm) $(CC_smm) $(LDFLAGS) -nostdlib -r -o $@ -Wl,--wrap,__divdi3 -Wl,--wrap,__udivdi3 -Wl,--wrap,__moddi3 -Wl,--wrap,__umoddi3 -Wl,--start-group $(smm-objs) $(LIBGCC_FILE_NAME_smm) -Wl,--end-group Cheers, Sean

And sorry if I was too hard on kolibrios. It's totally ]wonderful that they are building a from-the-bottom-up OS that gives ]people a close view of how things really work. ] ]ron Thank you and everyone for all the ideas and suggestions. Rudolf pointed out that coreboot already has an option for setting up the PCI config space 3C register: CONFIG_PIRQ_ROUTE. This initially looked like the proper way to enable the PIC mode routing code. On the other hand, experiments suggest this might not be the best way to do it. Testing Ubuntu with the E350M1 OEM BIOS gives these results for the south bridge SATA controller: grub options: acpi=off noapic debugger: clear SATA controller 3C register before Ubuntu boot. result: ahci 0000:00:11.0: can't find IRQ for PCI INT A; please try using pci=biosirq irq 10: nobody cared (try booting with the "irqpoll" option) Disabling IRQ #10 ata4.00: qc timeout (cmd 0xa1) grub options: acpi=off noapic debugger: clear SATA controller PIC routing before Ubuntu boot. result: SATA operation is extremely slow. Apparently the SATA ISR is called occasionally due to interrupt sharing. In PIC mode with acpi=off, the OS can only look at the MPS table or PIR table for interrupt info. These don't tell the OS what interrupt BIOS has assigned. In addition, the tables don't give enough info to allow the OS to program the interrupt itself. So to make Ubuntu work in PIC mode using MPS or PIR tables, both the 3C register and SB routing register must be setup by BIOS. This leads to an argument that CONFIG_PIRQ_ROUTE shouldn't exist. Instead, the PIC routing and 3C reporting should be done any time the MPS or PIR tables are included. Thanks, Scott
