2020-06-14soc/amd/picasso: Explicitly disable legacy UARTRaul E Rangel
The legacy UARTs are supposed to default to off according to the documentation (PPR for AMD Family 17h Model 18h). But legacy UART Range_0 is enabled after reset. The PSP might be enabling it or the documentation might be wrong. Having it enabled causes problems though. We have ACPI nodes defining MMIO UARTs, and the kernel also probes for legacy UARTs. This results in two drivers accessing the same device, one via MMIO and one via IO. I suspect this was the cause of the garbage serial output. Before the change you would see the following in the console: [ 0.741108] serial8250: ttyS3 at I/O 0x2e8 (irq = 3, base_baud = 115200) is a 16550A After this change, we no longer see it.

All AMD CPU families supported in coreboot have BIOSRAM space. Looking at the source code, every family could have the same API to save and restore cbmem top or UMA base and size. Unify BIOSRAM layout and add implementation for cbmem top and UMA storing. Also replace the existing implementation of cbmem top and UMA with the BIOSRAM access.

2019-12-04soc/amd/common/block/acpimmio: fix ACPIMMIO decode enable functionMichał Żygowski
According to BKDGs for families 15h 60-6fh or newer and families 16h the ACPI MMIO decode enable bit is the second LSB, not the first LSB. Additionally create another enable function for older families where the register and bit is different. It does not seem to impact any current board, but may be crucial for incoming C bootblock implementations when this bit will need to be set very early. Most likely this bit is set by AGESA right now.

Change the stoneyridge definitions into picasso. The named 0 and 1 buses are controlled by the PSP and not directly accessible by host firmware. I2C4 operates only in slave mode so is not added to to the bus clear-after-reset sequence. The I2C controller is fundamentally the same as on Stoney Ridge so the ability to clear a potentially jammed bus is still required.

2019-07-02soc/amd/picasso: Create picasso as a copy of stoneyridgeMartin Roth
So that everyone can see what's being updated from stoney, we're starting with a direct copy of the stoney directory. There are arguments both for and against doing it this way, but I believe This the most transparent way. We've moved much of the duplicated stoney code into the soc/amd/common directory and will continue that work as it becomes obvious that we have unchanged code between the SOCs. Makefile.inc has been renamed as makefile.inc so that it won't build in jenkins until the directory is updated. Other than that change, this is an exact copy of the stoneyridge SOC directory which will be updated in the follow-on commits in the patch train.
