2019-12-04amdblocks/acpimmio: Unify BIOSRAM usageMichał Żygowski
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.

2019-10-20soc/amd/picasso: Update UARTsMarshall Dawson
Add a function to uart.c to ensure the right IOMux settings are programmed for the console UART. Update Kconfig to reflect the new addresses. Give the user the ability to downclock the UARTs' refclock to 1.8342MHz. Add the abiltiy to use an APU UART at a legacy I/O address. Update the AOAC register configuration for the two additional UARTs.

2019-10-20soc/amd/picasso: Update southbridgeMarshall Dawson
Picasso's FCH has many similarities to Stoney Ridge, so few changes are necessary. The most notable changes are: * Update the index values for the C00/C01 interrupt routing * FORCE_STPCLK_RETRY is not present * PCIB is not defined * FCH MISC Registers 0xfed80e00 numbering has changed * C-state base moves from PM register to MSR * Add option to determine the intended MUX settion for LPC vs. eMMC * Remove the LEGACY_FREE option Signed-off-by: Marshall Dawson <marshalldawson3rd@gmail.com> Change-Id: I69dfc4a875006639aa330385680d150331840e40 Reviewed-on: https://review.coreboot.org/c/coreboot/+/33770 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Martin Roth <martinroth@google.com>

2019-09-13soc/amd/picasso: Refactor AOAC enablingMarshall Dawson
Replace the raw register definitions with device numbers and macros for determining the register offsets. Rewrite the source to refer to AOAC device numbers instead of a structure. Remove the calculated offset for the console UART. Picasso's UARTs are not contiguous so handle them separately.

2019-08-09soc/amd/picasso: Update i2c supportMarshall Dawson
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. Program Picasso's new pad control registers in the MISC AcpiMmio space according to the recommended settings.

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.
