2018-06-26arm64: Reimplement mmu_disable() in assemblyJulius Werner
Disabling the MMU with proper cache behavior is a bit tricky on ARM64: you can flush the cache first and then disable the MMU (like we have been doing), but then you run the risk of having new cache lines allocated in the tiny window between the two, which may or may not become a problem when those get flushed at a later point (on some platforms certain memory regions "go away" at certain points in a way that makes the CPU very unhappy if it ever issues a write cycle to them again afterwards). The obvious alternative is to first disable the MMU and then flush the cache, ensuring that every memory access after the flush already has the non-cacheable attribute. But we can't just flip the order around in the C code that we have because then those accesses in the tiny window in-between will go straight to memory, so loads may yield the wrong result or stores may get overwritten again by the later cache flush. In the end, this all shouldn't really be a problem because we can do both operations purely from registers without doing any explicit memory accesses in-between. We just have to reimplement the function in assembly to make sure the compiler doesn't insert any stack accesses at the wrong points.

Some arm64 files that were imported from other projects use the __ASSEMBLY__ macro to test whether a header is included from a C or an assembly file. This patch switches them to the coreboot standard __ASSEMBLER__, which has the advantage of being a GCC builtin so that the including file doesn't have to supply it explicitly.

Instead of just checking the immediate parent for an device name, walk up the tree to check if any parent can identify the device. This allows devices to be nested more than one level deep and still have them identified in one place by the SOC. The recursive method calling this function has been changed to handle a null return from acpi_device_name and abort instead of continuing and perhaps forming an invalid ACPI path.

2018-05-22Introduce bootblock self-decompressionJulius Werner
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.

2018-05-04lib/bootmem: Add more bootmem tagsPatrick Rudolph
Introduce new bootmem tags to allow more fine grained control over buffer allocation on various platforms. The new tags are: BM_MEM_RAMSTAGE : Memory where any kind of boot firmware resides and that should not be touched by bootmem (by example: stack, TTB, program, ...). BM_MEM_PAYLOAD : Memory where any kind of payload resides and that should not be touched by bootmem. Starting with this commit all bootmem methods will no longer see memory that is used by coreboot as usable RAM. Bootmem changes: * Introduce a weak function to add platform specific memranges. * Mark memory allocated by bootmem as BM_TAG_PAYLOAD. * Assert on failures. * Add _stack and _program as BM_MEM_RAMSTAGE. ARMv7 and ARMv8 specific changes: * Add _ttb and _postram_cbfs_cache as BM_MEM_RAMSTAGE. ARMv7 specific changes: * Add _ttb_subtables as BM_MEM_RAMSTAGE.

2018-05-03arch/x86: Relocate GDT in verstage, romstage, and postcarHannah Williams
In each stage keep GDT in the code region. This accommodates platforms, such as glk, that are executing out of CAR. The gdt is small and loading it is trivial so just do it unconditionally instead of introducing another Kconfig.

2018-05-03arch/x86: reduce complexity in assembly_entry.SAaron Durbin
Now that VBOOT_STARTS_IN_BOOTBLOCK depends on C_ENVIRONMENT_BOOTBLOCK, remove the complications in assembly_entry.S. There's no platform utilizing romcc bootblock and needing to handle verified boot after bootblock as well as not using verified boot. That combination makes things very complicated. Clean up the complication as it's not a combination that needs to be supported.

Linux (4.16) assumes that the PIT interrupt is connected to the pin 0 of the IOAPIC[0] and panics otherwise. This might be a Linux bug. The MP Specification 1.4 does seem to mandate sequential ordering for bus entries, but not for the I/O APICs.
