2024-06-12soc/sifive/fu540/chip.c: Add RAM resourcesMaximilian Brune
Add RAM region so that the payload can be placed in there without coreboot complaining that the payload doesn't target a RAM region.

2024-06-12soc/sifive/fu540/memlayout.ld: Enlarge OpenSBI regionMaximilian Brune
OpenSBI got bigger and doesn't fit anymore in 128K which causes coreboot to not compiler anymore because the region overlaps with ramstage This patch simply increases the size and uses the OpenSBI linker macro instead.

2024-01-31include/device/device.h: Remove CHIP_NAME() macroNicholas Sudsgaard
Macros can be confusing on their own; hiding commas make things worse. This can sometimes be downright misleading. A "good" example would be the code in soc/intel/xeon_sp/spr/chip.c: CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev, This appears as CHIP_NAME() being some struct when in fact these are defining 2 separate members of the same struct. It was decided to remove this macro altogether, as it does not do anything special and incurs a maintenance burden.

2021-02-19memlayout: Store region sizes as separate symbolsJulius Werner
This patch changes the memlayout macro infrastructure so that the size of a region "xxx" (i.e. the distance between the symbols _xxx and _exxx) is stored in a separate _xxx_size symbol. This has the advantage that region sizes can be used inside static initializers, and also saves an extra subtraction at runtime. Since linker symbols can only be treated as addresses (not as raw integers) by C, retain the REGION_SIZE() accessor macro to hide the necessary typecast.

2020-06-13treewide: Add Kconfig variable MEMLAYOUT_LD_FILEFurquan Shaikh
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows SoC/mainboard to provide a linker file for the platform. x86 already provides a default memlayout.ld under src/arch/x86. With this new Kconfig variable, it is possible for the SoC/mainboard code for x86 to provide a custom linker file as well. Makefile.inc is updated for all architectures to use this new Kconfig variable instead of assuming memlayout.ld files under a certain path. All non-x86 boards used memlayout.ld under mainboard directory. However, a lot of these boards were simply including the memlayout from SoC. So, this change also updates these mainboards and SoCs to define the Kconfig as required. BUG=b:155322763 TEST=Verified that abuild with --timeless option results in the same coreboot.rom image for all boards.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2019-12-11fmap: Make FMAP_CACHE mandatory if it is configured inJulius Werner
Now that we have a CONFIG_NO_FMAP_CACHE to completely configure out the pre-RAM FMAP cache code, there's no point in allowing the region to be optional anymore. This patch makes the section required by the linker. If a board doesn't want to provide it, it has to select NO_FMAP_CACHE. Adding FMAP_CACHE regions to a couple more targets that I think can use them but I don't know anything about... please yell if one of these is a bad idea and I should mark them NO_FMAP_CACHE instead.
