Trouble with coreboot for Roda RK9

[Dmitry Bagryanskiy]

Hello Nico,

Could you please help me to solve some problems?
Laptop: Roda RK9 13", 15" and 17"

Why can't I read the condition GP1 - GP4?
When I start the program superiotool with original bios, it shows regular results, when I start the program superiotool with coreboot the program shows 0 at GP1-GP4. It is in GP4 the DIP switcher locates  to chose the type of  LCD.

Thank you
Best regards, Dmitry Bagryanskiy

I'm sorry, but I can only confirm your problem. I tried reading those
GPIOs with the coreboot version we had on our RK9 and everything worked
out. After flashing the current upstream version, the VGA output was
garbled. So this is a regression which needs further investigation. I
can't currently work on this, but if you like to bisect the problem:
I guess, commit 11a7db3 should be a working starting point.

Kind regards,
Nico

Hello Nico,

Problem solution with registers.
Laptop: Roda RK9 13", 15" and 17"

I solved the problem with GP1-GP4 registers. It is needen to change the mask for decosding the port  0x600 on LPC.
pci_write_config32(LPC_DEV, D31F0_GEN1_DEC, 0x001f0601);
Also preparation for opening the ports for COM3 and COM4
//Enable Com3
pci_write_config32(LPC_DEV, D31F0_GEN2_DEC, 0x001c02e1);
//Enable Com4
pci_write_config32(LPC_DEV, D31F0_GEN3_DEC, 0x001c03e1);

Thank you
Best regards, Dmitry Bagryanskiy

GEN*_DEC should not be set to com* ports. Instead there are dedicated
bits for enabling decode of serial port ranges. Consult southbridge
documentation.

I'm not sure how changing the mask helps. Please provide a patch, so
I can better understand what you are doing.

Current code sets this to 0x000c0601, bits 16, 17 are reserved and bit
20 should IIRC only help with addresses from 0x610 to 0x61f.

There are only dedicated settings for two COM ports. Looks like Dmitry
wants to enable a 3rd and 4th port.
