2019-08-26AUTHORS: Move src/arch/arm copyrights into AUTHORS fileMartin Roth
As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Additional changes in this patch: - Make sure files say that they're part of the coreboot project - Move descriptions below the license header - Fix some spacing Signed-off-by: Martin Roth <martin@coreboot.org> Change-Id: Id5f26a73f0df366651c076a94975bce1fb321b70 Reviewed-on: https://review.coreboot.org/c/coreboot/+/34605 Reviewed-by: Werner Zeh <werner.zeh@siemens.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

2019-07-12arch, include, soc: Use common stdint.hJacob Garber
There are only minimal differences between the architecture specific stdint.h implementations, so let's tidy them up and merge them together into a single file. In particular, - Use 'unsigned long' for uintptr_t. This was already the case for x86 and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64 used 'unsigned long long'. This change allows using a single integer type for uintptr_t across all architectures, and brings it into consistency with the rest of the code base, which generally uses 'unsigned long' for memory addresses anyway. This change required fixing several assumptions about integer types in the arm code. - Use _Bool as the boolean type. This is a specialized boolean type that was introduced in C99, and is preferrable over hacking booleans using integers. romcc sadly does not support _Bool, so for that we stick with the old uint8_t. - Drop the least and fast integer types. They aren't used anywhere in the code base and are an unnecessary maintenance burden. Using the standard fixed width types is essentially always better anyway. - Drop the UINT64_C() macro. It also isn't used anywhere and doesn't provide anything that a (uint64_t) cast doesn't. - Implement the rest of the MIN and MAX numerical limits. - Use static assertions to check that the integer widths are correct.

2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

2018-10-11selfboot: remove bounce buffersRonald G. Minnich
Bounce buffers used to be used in those cases where the payload might overlap coreboot. Bounce buffers are a problem for rampayloads as they need malloc. They are also an artifact of our x86 past before we had relocatable ramstage; only x86, out of the 5 architectures we support, needs them; currently they only seem to matter on the following chipsets: src/northbridge/amd/amdfam10/Kconfig src/northbridge/amd/lx/Kconfig src/northbridge/via/vx900/Kconfig src/soc/intel/fsp_baytrail/Kconfig src/soc/intel/fsp_broadwell_de/Kconfig The first three are obsolete or at least could be changed to avoid the need to have bounce buffers. The last two should change to no longer need them. In any event they can be fixed or pegged to a release which supports them. For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the value needed in 1999 for the 32-bit Linux kernel, the original ramstage) to 0xe00000 (14 Mib) which will put the non-relocatable x86 ramstage out of the way of any reasonable payload until we can get rid of it for good. 14 MiB was chosen after some discussion, but it does fit well: o Fits in the 16 MiB cacheable range coreboot sets up by default o Most small payloads are well under 14 MiB (even kernels!) o Most large payloads get loaded at 16 MiB (especially kernels!) With this change in place coreboot correctly still loads a bzImage payload. Werner reports that the 0xe00000 setting works on his broadwell systems.

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.

2017-03-28Remove libverstage as separate library and source file classJulius Werner
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are linked directly into the bootblock or the romstage. However, they're still compiled with a separate "libverstage" source file class, linked into an intermediate library and then linked into the final destination stage. There is no obvious benefit to doing it this way and it's unclear why it was chosen in the first place... there are, however, obvious disadvantages: it can result in code that is used by both libverstage and the host stage to occur twice in the output binary. It also means that libverstage files have their separate compiler flags that are not necessarily aligned with the host stage, which can lead to weird effects like <rules.h> macros not being set the way you would expect. In fact, VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86 because their libverstage code that gets compiled into the romstage sets ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to run pre-migration. This patch resolves these problems by removing the separate library. There is no more difference between the 'verstage' and 'libverstage' classes, and the source files added to them are just treated the same way a bootblock or romstage source files in configurations where the verstage is linked into either of these respective stages (allowing for the normal object code deduplication and causing those files to be compiled with the same flags as the host stage's files). Tested this whole series by booting a Kevin, an Elm (both with and without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

Currently, there is support for armv7-a and armv7-m and armv7-a files has been modfied to accommodate armv7-r by adding ENV_ARMV7_A, ENV_ARMV7_R and ENV_ARMV7_M constants to src/include/rules.h. armv7-r exceptions support will added in a later time.

2016-05-02arch: introduce architecture dependent common variablesAaron Durbin
Stefan and others have discussed their interest in only including options in Kconfig that are directly associated with building a coreboot image. There are variables that are architecture dependent that are utilized in the coreboot infrastructure. To meet that goal, introduce <arch/cbconfig.h> header file which defines variables for the coreboot infrastructure that are architecture dependent but utilized in common infrastructure.
