2021-06-02soc/amd/picasso: remove warm reset flag codeFelix Held
Since the MCA(X) registers have defined values on the cold boot path, the is_warm_reset check can be dropped. Also the warm reset bit in the NCP_ERR register doesn't behave as the PPR [1] suggested; no matter if something was written to the register or the machine went through a warm reset cycle, the NCP_WARM_BOOT bit never got set.

2021-05-22soc/amd/cezanne,picasso/reset: use byte I/O read for NCP_ERRFelix Held
NCP_ERR is a 1 byte register in I/O-space, so use inb and not inw. The variable the result gets assigned to is also a uint8_t.

The FSP integration code needs this function to be present. It's not supposed to be called, but if it is, it'll print an error and call the SoC's cold reset function.

2020-08-03Change all assert(0) to BUG()Julius Werner
I would like to make assertions evaluate at compile time where possible, but sometimes people used a literal assert(0) to force an assertion in a certain code path. We already have BUG() for that so let's just replace those instances with that.

2020-05-01soc/amd/picasso: Add FSP support for including AGESAMarshall Dawson
AMD has rewritten AGESA (now at v9) for direct inclusion into UEFI build environments. Therefore, unlike the previous Arch2008 (a.k.a. v5), it can't be built without additional source, e.g. by combining with EDK II, and it has no entry points for easily building it into a legacy BIOS. AGESA in coreboot now relies on the FSP 2.0 framework published by Intel and uses the existing fsp2_0 driver. * Add fsp_memory_init() to romstage.c. Although Picasso comes out of reset with DRAM alive, this call is added to maximize compatibility and facilitate internal development. Future work may look at removing it. AGESA reports the memory map to coreboot via HOBs returned from fsp_memory_init(). * AGESA currently sets up MTRRs, as in most older generations. Take ownership back immediately before running ramstage. * Remove cbmem initialization, as the FSP driver handles this. * Add chipset_handle_reset() for compatibility. * Top of memory is determined by the FSP driver checking the HOBs passed from AGESA. Note that relying on the TOM register happens to be misleading when UMA is below 4GB.

2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

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.
