2014-03-04Add a generic register script handlerDuncan Laurie
This is based on the RCBA configuration setup from haswell. It handles PCI, BARs, IO, MMIO, and baytrail-specific IOSF. I did not extend it to handle MSR yet but that would be another potential register type. There are a number of approaches to this kind of thing, but in the end they have a lot of switch statements and a mass of #defines. I'm not particularly set on any of the details so comments welcome.

2014-01-15Re-declare CACHE_ROM_SIZE as aligned ROM_SIZE for MTRRKyösti Mälkki
This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be set with values that are not power of 2. The region programmed as WB cacheable will include all of ROM_SIZE. Side-effects to consider: Memory region below flash may be tagged WRPROT cacheable. As an example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB. Since this can overlap CAR, we add an explicit test and fail on compile should this happen. To work around this problem, one needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and define a smaller region for WB cache. With this change flash regions outside CBFS are also tagged WRPROT cacheable. This covers IFD and ME and sections ChromeOS may use.

2013-11-19Add GRUB2 payload to build systemVladimir Serbinenko
Since a long time GRUB 2 is a viable payload alternative to SeaBIOS and FILO. So make it easy for coreboot users to use GRUB 2 as a payload by integrating it into coreboot’s build system, so it can be selected in Kconfig. As the last GRUB 2 release 2.00 is too old and has several bugs when used as a coreboot payload only allow to build GRUB 2 master until a new GRUB release is done. The downside is, that accidental breakage in GRUB’s upstream does not affect coreboot users. Currently the GRUB 2 payload is built with the default modules which results in an uncompressed size of around 730 kB. Compressed it has a size of 340 kB, so it should be useable with 512 kB flash ROMs. Tested with QEMU.

The cooperative multitasking support allows the boot state machine to be ran cooperatively with other threads of work. The main thread still continues to run the boot state machine (src/lib/hardwaremain.c). All callbacks from the state machine are still ran synchronously from within the main thread's context. Without any other code added the only change to the boot sequence when cooperative multitasking is enabled is the queueing of an idlle thread. The idle thread is responsible for ensuring progress is made by calling timer callbacks. The main thread can yield to any other threads in the system. That means that anyone that spins up a thread must ensure no shared resources are used from 2 or more execution contexts. The support is originally intentioned to allow for long work itesm with busy loops to occur in parallel during a boot. Note that the intention on when to yield a thread will be on calls to udelay().

2013-03-21cbmem: dynamic cbmem supportAaron Durbin
This patch adds a parallel implementation of cbmem that supports dynamic sizing. The original implementation relied on reserving a fixed-size block of memory for adding cbmem entries. In order to allow for more flexibility for adding cbmem allocations the dynamic cbmem infrastructure was developed as an alternative to the fixed block approach. Also, the amount of memory to reserve for cbmem allocations does not need to be known prior to the first allocation. The dynamic cbmem code implements the same API as the existing cbmem code except for cbmem_init() and cbmem_reinit(). The add and find routines behave the same way. The dynamic cbmem infrastructure uses a top down allocator that starts allocating from a board/chipset defined function cbmem_top(). A root pointer lives just below cbmem_top(). In turn that pointer points to the root block which contains the entries for all the large alloctations. The corresponding block for each large allocation falls just below the previous entry. It should be noted that this implementation rounds all allocations up to a 4096 byte granularity. Though a packing allocator could be written for small allocations it was deemed OK to just fragment the memory as there shouldn't be that many small allocations. The result is less code with a tradeoff of some wasted memory. +----------------------+ <- cbmem_top() | +----| root pointer | | | +----------------------+ | | | |--------+ | +--->| root block |-----+ | | +----------------------+ | | | | | | | | | | | | | | alloc N |<----+ | | +----------------------+ | | | | | | | | | \|/ | alloc N + 1 |<-------+ v +----------------------+ In addition to preserving the previous cbmem API, the dynamic cbmem API allows for removing blocks from cbmem. This allows for the boot process to allocate memory that can be discarded after it's been used for performing more complex boot tasks in romstage. In order to plumb this support in there were some issues to work around regarding writing of coreboot tables. There were a few assumptions to how cbmem was layed out which dictated some ifdef guarding and other runtime checks so as not to incorrectly tag the e820 and coreboot memory tables. The example shown below is using dynamic cbmem infrastructure.

2013-03-21coreboot: introduce CONFIG_RELOCATABLE_RAMSTAGEAaron Durbin
This patch adds an option to build the ramstage as a reloctable binary. It uses the rmodule library for the relocation. The main changes consist of the following: 1. The ramstage is loaded just under the cmbem space. 2. Payloads cannot be loaded over where ramstage is loaded. If a payload is attempted to load where the relocatable ramstage resides the load is aborted. 3. The memory occupied by the ramstage is reserved from the OS's usage using the romstage_handoff structure stored in cbmem. This region is communicated to ramstage by an CBMEM_ID_ROMSTAGE_INFO entry in cbmem. 4. There is no need to reserve cbmem space for the OS controlled memory for the resume path because the ramsage region has been reserved in #3. 5. Since no memory needs to be preserved in the wake path, the loading and begin of execution of a elf payload is straight forward.

2013-03-18lib: add rmodule supportAaron Durbin
A rmodule is short for relocation module. Relocaiton modules are standalone programs. These programs are linked at address 0 as a shared object with a special linker script that maintains the relocation entries for the object. These modules can then be embedded as a raw binary (objcopy -O binary) to be loaded at any location desired. Initially, the only arch support is for x86. All comments below apply to x86 specific properties. The intial user of this support would be for SMM handlers since those handlers sometimes need to be located at a dynamic address (e.g. TSEG region). The relocation entries are currently Elf32_Rel. They are 8 bytes large, and the entries are not necessarily in sorted order. An future optimization would be to have a tool convert the unsorted relocations into just sorted offsets. This would reduce the size of the blob produced after being processed. Essentialy, 8 bytes per relocation meta entry would reduce to 4 bytes.

The console drivers (especially serial drivers) in Kconfig were named in different styles. This change will rename configuration names to a better naming style. - EARLY_CONSOLE: Enable output in pre-ram stage. (Renamed from EARLY_SERIAL_CONSOLE because it also supports non-serial) - CONSOLE_SERIAL: Enable serial output console, from one of the serial drivers. (Renamed from SERIAL_CONSOLE because other non-serial drivers are named as CONSOLE_XXX like CONSOLE_CBMEM) - CONSOLE_SERIAL_UART: Device-specific UART driver. (Renamed from CONSOLE_SERIAL_NONSTANDARD_MEM because it may be not memory-mapped) - HAVE_UART_SPECIAL: A dependency for CONSOLE_SERIAL_UART. Verified to boot on x86/qemu and armv7/snow, and still seeing console messages in romstage for both platforms.
