All,
After reviewing some of the comments on the ASUS KGPE-D16 being
essentially too large of a system and too expensive for many people, and
the fact that modern, blob-free systems are not really available in the
mid-range arena, Raptor Engineering would like to offer to create a
native initalization blob-free port for the ASUS KCMA-D8, which is
essentially the KGPE-D16's ATX-compatible "little brother".
We would be asking $15,000 for the port, including upstreaming to the
master coreboot tree. We already have extensive experience with these
Family 10h/15h boards, and would be able to create a port of similar
quality to the existing KGPE-D16 source in terms of both code quality
and overall functionality.
If this is something you might be interested in please let me know. We
are able to accept multiple payments from various sources for the same
project (within limits), so if this is something your local Linux groups
or similar might be interested in we should be able to keep the cost on
any one individual or organization to a reasonable level.
Thank you for your consideration,
- --

Thank you for the hint. I inspected that, but the PCI-IDs actually look the same:
00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Trinity [Radeon HD 7480D] [1002:9993]
(A4-5300)
and
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8670D] (prog-if 00 [VGA controller])
(A10-6700)
Looks like the VGA BIOS is really different:
# diff vgabios_a4-5300.bin vgabios_a10_6700.bin
Binary files vgabios_a4-5300.bin and vgabios_a10_6700.bin differ
Guess I will have to to "update" the VGA BIOS then.
Cheers, Daniel

Hi!
I need help to porting coreboot Asus M4a785m on Asus M5a78l-m lx3.
I'm trying to porting coreboot on the motherboard Asus M5a78l-m lx3 (rs780l/sb710). I cannot find documentation for the northbridge rs780l.
My configuration: cpu - Athlon 2 x2 220 (K10), memory - 2 + 2 Gb DDR3, video - Asus GT520, sata segate hdd 500Gb, sata asus dvd-rw.
I have a positive result for the configuration with memory 2Gb and external video card Asus GT520. I can load Linux kernel 2.6.
But, i have two problems:
1. I cannot load coreboot with internal graphics card (hd 3000). Coreboot stops loading and to print on console "Calling option ROM…". May be the problems with gfx configuration?
2. I cannot run Linux with memory 4Gb. Coreboot is loading, SeaBios is loading too, but Linux stop load on usb3-2 and ata1 setup. May be the problems with memory map?
Please, help me. I can provide all the necessary information from the log coreboot, SeaBios and Linux.
Thanks.

Can you confirm that you see the full coreboot log on your UART? With
log level >= debug, it should end with lines about loading the payload,
containing a line starting with "Jumping to boot code at".
If you see this line, it's unlikely to be a coreboot issue. If not,
please provide a full log with highest log level. Also the output of
`lspci -xxx`, `cbmem -c` and your devicetree.cb might be helpful.
Another way to test the UART is to use Linux' earlycon driver, e.g. with
earlycon=uart8250,io,0x3f8,115200n8 in your kernel command line. This
driver is simpler than the serial8250 (it doesn't use interrupts and is
closer to what coreboot's driver does).

Julius,
wouldn't he also need gbb_utility to set the flags, in addition to
(CrOS) flashrom to
be able to read/write just the GBB region? That's why I suggested he use my
ChromeOS Firmware Utility Script, since it would automatically download the
required binaries as well as ensure the flags were set to a sane value.
But as you, no need to change the flags as set to boot ChromeOS
cheers,
Matt

in theory (I've just checked the code, never tried) the Linux driver
supports MMIO UARTs too if you give it the same entry (PNP0501) with
a memory resource instead of the io ports.
Maybe this works in other OS' too?

Yes, I was wrong. After reading the other threads and talking with
Martin, it indeed seems to be a toolchain issue.
However, the new toolchain had many advantages over the previous one,
and the code was not in (our) ARM TF at the time we uprevved.
The maintenance burden of keeping different versions of toolchains
supported for different architectures as part of the reference toolchain
is imho almost always significantly higher than actually fixing the
issues. (Especially if they are not time critical)
Martin produced a binutils fix for the issue. Whether the binutils
people will find it to be the "right" fix is still to be found out, but
it seems to allow compiling the latest, unmodified ARM TF.

Hi, All,
I want to add support MMIO UART support on OS.
I checked the file pnp_uart.asl.
For IO UART, a device with EisaId("PNP0501") is added into DSDT, the windows can detect the COM port in device manager.
I am wondering if MMIO UART also have that convinient feature.
Or I need to build a driver for each OS?
Thanks.
Joe
