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.

2015-08-13amd: raminit sysinfo offset fixAaron Durbin
The sysinfo object within the k8 ram init is used to communicate progess/status from all the nodes in the system. However, the code was assuming where the sysinfo object lived in cache-as-ram. The layout of cache-as-ram is dynamic so one needs to do the lookup of the correct address at runtime. The way the amd code is compiled by #include'ing .c files makes the solution a little more complex in that some cache-as-ram support code needed to be refactored.

2015-01-06cpu: Drop print_ implementation from non-romcc boardsStefan Reinauer
Because we had no stack on romcc boards, we had a separate, not as powerful clone of printk: print_*. Back in the day, like more than half a decade ago, we migrated a lot of boards to printk, but we never cleaned up the existing code to be consistent. instead, we worked around the problem with a very messy console.h (nowadays the mess is hidden in romstage_console.c and early_print.h) This patch cleans up the cpu code to use printk() on all non-ROMCC boards.

2014-11-14AMD (K8/fam10): Rewrite CAR migration in post_cache_as_ramKyösti Mälkki
Old routine copied all of CAR region as-is right below CONFIG_RAMTOP. Most of this region was reserved to interleave AP CPU address spaces and unused on BSP CPU. The only part of CAR region requiring a copy in RAM is the sysinfo structure. Improved routine changes this as follows: A region of size 'backup_size' below CONFIG_RAMTOP is cleared. In case of S3 resume, OS context from this region is first copied to high memory (CBMEM_ID_RESUME). At stack switch, CAR stack is discarded. Top of the stack for BSP is located at 'CONFIG_RAMTOP - car_size' for the remaining part of the romstage. This region is part of 'backup_size' and was zeroed before the switch took place. Before CAR is torn down the region of CAR_GLOBALS (and CAR_CBMEM), including the relevant sysinfo data for AP nodes memory training, is copied at 'CONFIG_RAMTOP - car_size'. NOTE: While CAR_GLOBAL variables are recovered, there are currently no means to calculate their offsets in RAM. NOTE: Boards with multiple CPU packages are likely already broken since bbc880ee amdk8/amdfam10: Use CAR_GLOBAL for sysinfo This moved the copy of sysinfo in RAM from above the stack to below the stack, but code for AP CPU's was not adjusted accordingly.

2014-04-26Rename coreboot_ram stage to ramstageFurquan Shaikh
Rename coreboot_ram stage to ramstage. This is done in order to provide consistency with other stage names (bootblock, romstage) and to allow any Makefile rule generalization, required for patches to be submitted later.

Compiler may do loads of optimisations around stack switch and so it's allowed to break stack switch as it sees fit. Do it in assembly instead. Not tested.
