* Introduce bootblock self-decompressionJulius Werner2018-05-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Masked ROMs are the silent killers of boot speed on devices without memory-mapped SPI flash. They often contain awfully slow SPI drivers (presumably bit-banged) that take hundreds of milliseconds to load our bootblock, and every extra kilobyte of bootblock size has a hugely disproportionate impact on boot speed. The coreboot timestamps can never show that component, but it impacts our users all the same. This patch tries to alleviate that issue a bit by allowing us to compress the bootblock with LZ4, which can cut its size down to nearly half. Of course, masked ROMs usually don't come with decompression algorithms built in, so we need to introduce a little decompression stub that can decompress the rest of the bootblock. This is done by creating a new "decompressor" stage which runs before the bootblock, but includes the compressed bootblock code in its data section. It needs to be as small as possible to get a real benefit from this approach, which means no device drivers, no console output, no exception handling, etc. Besides the decompression algorithm itself we only include the timer driver so that we can measure the boot speed impact of decompression. On ARM and ARM64 systems, we also need to give SoC code a chance to initialize the MMU, since running decompression without MMU is prohibitively slow on these architectures. This feature is implemented for ARM and ARM64 architectures for now, although most of it is architecture-independent and it should be relatively simple to port to other platforms where a masked ROM loads the bootblock into SRAM. It is also supposed to be a clean starting point from which later optimizations can hopefully cut down the decompression stub size (currently ~4K on RK3399) a bit more. NOTE: Bootblock compression is not for everyone. Possible side effects include trying to run LZ4 on CPUs that come out of reset extremely underclocked or enabling this too early in SoC bring-up and getting frustrated trying to find issues in an undebuggable environment. Ask your SoC vendor if bootblock compression is right for you.

* arch/x86: introduce postcar stage/phaseAaron Durbin2016-03-231-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain chipsets don't have a memory-mapped boot media so their code execution for stages prior to DRAM initialization is backed by SRAM or cache-as-ram. The postcar stage/phase handles the cache-as-ram situation where in order to tear down cache-as-ram one needs to be executing out of a backing store that isn't transient. By current definition, cache-as-ram is volatile and tearing it down leads to its contents disappearing. Therefore provide a shim layer, postcar, that's loaded into memory and executed which does 2 things: 1. Tears down cache-as-ram with a chipset helper function. 2. Loads and runs ramstage. Because those 2 things are executed out of ram there's no issue of the code's backing store while executing the code that tears down cache-as-ram. The current implementation makes no assumption regarding cacheability of the DRAM itself. If the chipset code wishes to cache DRAM for loading of the postcar stage/phase then it's also up to the chipset to handle any coherency issues pertaining to cache-as-ram destruction.

* x86: add standalone verstage supportAaron Durbin2015-10-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support x86 verstage one needs a working buffer for vboot. That buffer resides in the cache-as-ram region which persists across verstage and romstage. The current assumption is that verstage brings cache-as-ram up and romstage tears cache-as-ram down. The timestamp, cbmem console, and the vboot work buffer are persistent through in both romstage and verstage. The vboot work buffer as well as the cbmem console are permanently destroyed once cache-as-ram is torn down. The timestamp region is migrated. When verstage is enabled the assumption is that _start is the romstage entry point. It's currently expected that the chipset provides the entry point to romstage when verstage is employed. Also, the car_var_*() APIs use direct access when in verstage since its expected verstage does not tear down cache-as-ram. Lastly, supporting files were added to verstage-y such that an x86 verstage will build and link. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados using separate verstage.

| | | | | | | | | | | | | | | | Revise console source file dependency (especially for EARLY_CONSOLE) and interpret printk/console_init according to EARLY_CONSOLE setting (no-ops if EARLY_CONSOLE is not defined). Verified to boot on x86/qemu and armv7/snow. Disabling EARLY_CONSOLE correctly stops romstage messages on x86/qemu (armv7/snow needs more changes to work).

* console: Revise serial console configuration names.Hung-Te Lin2013-02-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* make early serial console support more genericDavid Hendricks2013-01-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch makes pre-RAM serial init more generic, particularly for platforms which do not necessarily need cache-as-RAM in order to use the serial console and do not have a standard 8250 serial port. This adds a Kconfig variable to set romstage-* for very early serial console init. The current method assumes that cache-as-RAM should enable this, so to maintain compatibility selecting CACHE_AS_RAM will also select EARLY_SERIAL_CONSOLE. The UART code structure needs some rework, but the use of ROMCC, romstage, and then ramstage makes things complex. uart.h now includes all .h files for all uarts. All 2 of them. This is actually a simplifying change. Change-Id: I089e7af633c227baf3c06c685f005e9d0e4b38ce Signed-off-by: David Hendricks <dhendrix@chromium.org> Signed-off-by: Ronald G.

* Get rid of drivers classPatrick Georgi2012-11-271-6/+6
| | | | | | | | | | | | | | | | | | The use of ramstage.a required the build system to handle some object files in a special way, which were put in the drivers class. These object files didn't provide any symbols that were used directly (but only via linker magic), and so the linker never considered them for inclusion. With ramstage.a gone, we can drop this special class, too.
