2017-03-28AGESA: Fork for new cache-as-ram init codeKyösti Mälkki
To gradually consolidate and improve AGESA board romstages, fork the original CAR setup code as a separate file. It becomes too messy with preprocessor to attempt make changes within the same file, and at end of patchset original becomes obsolete.

2017-03-28AGESA: Introduce AGESA_LEGACY and its counterpartKyösti Mälkki
We define AGESA_LEGACY as an implementation of mainboard that has its romstage main completely under mainboard/ directory. We have learnt from other platforms this approach has several downsides when it comes to making platform-wide improvements. We start by creating per-family romstage.c file, which boards will gradually take into use by removing the AGESA_LEGACY Kconfig option we here apply to all of them.

2017-03-16binaryPI: Fix SSE regression and align stack earlyKyösti Mälkki
When allowing use of SSE instructions, stack must be aligned to 16 bytes. Adjust x86 entry to C accordingly, by pushing values to maintain the alignment. For some builds, new toolchain and GCC-6.3 could emit SSE instruction 'andps (%esp),%xmm0' with incorrectly aligned esp, raising exception and thus preventing boot.

2017-03-08binaryPI platforms: Drop any ACPI S3 supportKyösti Mälkki
No board with binaryPI currently supports HAVE_ACPI_RESUME. For platforms with PSP the approach is also very different from what we previously had here. Furthermore, s3_resume.[ch] files under cpu/amd/pi do not distinguish between NonVolatile and Volatile buffers of S3 storage. This means the Volatile buffer that is maintained and available in CBMEM is unnecessarily copied to SPI flash. This has been fixed on open-source AGESA directory, so development of S3 suspend support with binaryPI is better continued with that. Unfortunately there are further complications and indications that open-source AGESA may have always had a low-memory corruption issue. This has to be investigated separately before restoring or claiming S3 is supported on binaryPI.

2017-03-07amd/pi/hudson: Move APIC enable to CPU fileMarshall Dawson
Relocate the enabling of the LAPIC out of the southbridge source and surround it with a check for CONFIG_UDELAY_LAPIC (typical for AMD systems). The LAPIC is now enabled for all cores; not only the BSP, and not only when the UART is used. This solves the problem of APs not having their APICs enabled when the timer is expected to be functional, e.g. verstage often uses do_printk_va_list() instead of do_printk() which exits early for APs when CONFIG_SQUELCH_EARLY_SMP=y. The changes were tested with two Gardenia builds, one using verstage and another with CONFIG_SQUELCH_EARLY_SMP=n.

Previously, all romstages for this northbridge family would compile via 1 single C file with everything included into the romstage.c file (!)

Both DDR2 and DDR3 have been completed TESTED on REACTS: passes all boot tests for 2 boards ASUS KGPE-D16 ASUS KFSN4-DRE Some extra changes were required to make it compile otherwise there were unused functions in included "c" files.

2016-11-22spi: Clean up SPI flash driver interfaceFurquan Shaikh
RW flag was added to spi_slave structure to get around a requirement on some AMD flash controllers that need to group together all spi volatile operations (write/erase). This rw flag is not a property or attribute of the SPI slave or controller. Thus, instead of saving it in spi_slave structure, clean up the SPI flash driver interface. This allows chipsets/mainboards (that require volatile operations to be grouped) to indicate beginning and end of such grouped operations. New user APIs are added to allow users to perform probe, read, write, erase, volatile group begin and end operations. Callbacks defined in spi_flash structure are expected to be used only by the SPI flash driver. Any chipset that requires grouping of volatile operations can select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and define callbacks for chipset_volatile_group_{begin,end}. spi_claim_bus/spi_release_bus calls have been removed from the SPI flash chip drivers which end up calling do_spi_flash_cmd since it already has required calls for claiming and releasing SPI bus before performing a read/write operation.

Zero-filling memory below 1 MiB resets car_migrated variable so any CAR GLOBALs are not addressed correctly for the remaining time in romstage. Also there is no actual need to do this as ramstage loader handles BSS. This fixes regression with commit 70cd54310 that broke fam10 boards with romstage spinlocks enabled.

This was eventually traced to concurrent access to the SP5100's SPI Flash controller by multiple APs during startup. Calls to the nvram read functions get_option and read_option call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash controller, thus placing the SP5100 in an invalid state. This limitation is not documented in any public AMD errata, and was only discovered through considerable debugging effort.
