2015-11-03cbmem: add coreboot table records for each cbmem entryAaron Durbin
In order to not expose the cbmem data structures to userland that are used by coreboot internally add each of the cbmem entries to a coreboot table record. The payload ABI uses coreboot tables so this just provides a shortcut for cbmem entries which were manually added previously by doing the work on behalf of all entries. A cursor structure and associated functions are added to the imd code for walking the entries in order to be placed in the coreboot tables. Additionally a struct lb_cbmem_entry is added that lists the base address, size, and id of the cbmem entry. BUG=chrome-os-partner:43731 BRANCH=None TEST=Booted glados. View coreboot table entries with cbmem.

The additional thing needed at this point is for the utilities to provide a printk() declaration within a <console/console.h> file.

2015-06-09cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() APIKyösti Mälkki
Squashed and adjusted two changes from chromium.git. Covers CBMEM init for ROMTAGE and RAMSTAGE. cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API There are several use cases for performing a certain task when CBMEM is first set up (usually to migrate some data into it that was previously kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them differently: timestamp migration is called explicitly from cbmem_initialize(), certain x86-chipset-specific tasks use the CAR_MIGRATION() macro to register a hook, and the CBMEM console is migrated through a direct call from romstage (on non-x86 and SandyBridge boards). This patch decouples the CAR_MIGRATION() hook mechanism from cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer description of what it really does. All of the above use cases are ported to this new, consistent model, allowing us to have one less line of boilerplate in non-CAR romstages. BRANCH=None BUG=None TEST=Built and booted on Nyan_Blaze and Falco with and without CONFIG_CBMEM_CONSOLE. Confirmed that 'cbmem -c' shows the full log after boot (and the resume log after S3 resume on Falco). Compiled for Parrot, Stout and Lumpy.

Oops. This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism to the cbmem_initialize() call in ramstage. The macro is split into explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as possible and prevent surprises (although just using a single macro and relying on the Makefiles to link an object into all appropriate stages would also work). This allows us to get rid of the explicit cbmemc_reinit() in ramstage (which I somehow accounted for in the last patch without realizing that timestamps work exactly the same way...), and replace the older and less flexible cbmem_arch_init() mechanism. Also added a size assertion for the pre-RAM CBMEM console to memlayout that could prevent a very unlikely buffer overflow I just noticed. BRANCH=None BUG=None TEST=Booted on Pinky and Falco, confirmed that ramstage timestamps once again show up. Compile-tested for Rambi and Samus.

For x86 systems employing CONFIG_LATE_CBMEM_INIT, set_top_of_ram() is called in ramstage to note the upper address of the 32-bit address space. This in turn is consumed by cbmem. However, in this scenario cbmem_top() cannot always be relied upon because get_top_of_ram() doesn't return the same value provided to set_top_of_ram(). To fix the inconsistency in ramstage save the value passed in to set_top_of_ram() and defer to it as the return value for cbmem_top().

1) Save the pointer to the FSP HOB list to low memory at address 0x614. This is the same location as CBMEM_RESUME_BACKUP - the two aren't used in the same platform, so overlapping should be OK. I didn't see any documentation that actually said that this location was free to use, and didn't need to be restored after use in S3 resume, but it looks like the DOS boot vector gets loaded juat above this location, so it SHOULD be ok. The alternative is to copy the memory out and store it in cbmem until we're ready to restore it. 2) When a request for the pointer to a CAR variable comes in, pass back the location inside the FSP hob structure. 3) Skip the memcopy of the CAR Data. The CAR variables do not get transitioned back into cbmem, but used out of the HOB structure. 4) Remove the BROKEN_CAR_MIGRATE Kconfig option from the FSP platform.

2014-03-11chromeos: provide option to dynamically allocate ram oops bufferAaron Durbin
Fixing the location of the ram oops buffer can lead to certain kernel and boot loaders being confused when there is a ram reservation low in the address space. Alternatively provide a mechanism to allocate the ram oops buffer in cbmem. As cbmem is usually high in the address space it avoids low reservation confusion. The patch uncondtionally provides a GOOG9999 ACPI device with a single memory resource describing the memory region used for the ramoops region. BUG=None BRANCH=baytrail,haswell TEST=Built and booted with and w/o dynamic ram oops. With the corresponding kernel change things behave correctly.

2014-02-16x86: provide infrastructure to backup default SMM regionAaron Durbin
Certain CPUs require the default SMM region to be backed up on resume after a suspend. The reason is that in order to relocate the SMM region the default SMM region has to be used. As coreboot is unaware of how that memory is used it needs to be backed up. Therefore provide a common method for doing this.

2014-02-15coreboot: infrastructure for different ramstage loadersAaron Durbin
There are 2 methods currently available in coreboot to load ramstage from romstage: cbfs and vboot. The vboot path had to be explicitly enabled and code needed to be added to each chipset to support both. Additionally, many of the paths were duplicated between the two. An additional complication is the presence of having a relocatable ramstage which creates another path with duplication. To rectify this situation provide a common API through the use of a callback to load the ramstage. The rest of the existing logic to handle all the various cases is put in a common place.
