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.

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.

The payload loader doesn't know about CBFS in DRAM and overwrites the CBFS while decompressing payloads, resulting in undefined behaviour. Mark the region as SRAM to make sure the payload won't overwrite the CBFS while decompressing. As payload is always decompressed to DRAM, it wouldn't touch SRAM memory regions.

2016-10-24RISCV: Clean up the common architectural codeRonald G. Minnich
This version of coreboot successfully starts a Harvey (Plan 9) kernel as a payload, entering main() with no supporting assembly code for startup. The Harvey port is not complete so it just panics but ... it gets started. We provide a standard payload function that takes a pointer argument and makes the jump from machine to supervisor mode; the days of kernels running in machine mode are over. We do some small tweaks to the virtual memory code. We temporarily disable two functions that won't work on some targets as register numbers changed between 1.7 and 1.9. Once lowrisc catches up we'll reenable them. We add the PAGETABLES to the memlayout.ld and use _pagetables in the virtual memory setup code. We now use the _stack and _estack from memlayout so we know where things are. As time goes on maybe we can kill all the magic numbers.

2016-08-18Kconfig: lay groundwork for not assuming SPI flash boot deviceAaron Durbin
Almost all boards and chipsets within the codebase assume or use SPI flash as the boot device. Therefore, provide an option for the boards/chipsets which don't currently support SPI flash as the boot device. The default is to assume SPI flash is the boot device unless otherwise instructed. This falls in line with the current assumptions, but it also allows one to differentiate a platform desiring SPI flash support while it not being the actual boot device. One thing to note is that while google/daisy does boot with SPI flash part no SPI API interfaces were ever implemented. Therefore, mark that board as not having a SPI boot device.

2015-04-14CBFS: Automate ROM image layout and remove hardcoded offsetsJulius Werner
Non-x86 boards currently need to hardcode the position of their CBFS master header in a Kconfig. This is very brittle because it is usually put in between the bootblock and the first CBFS entry, without any checks to guarantee that it won't overlap either of those. It is not fun to debug random failures that move and disappear with tiny alignment changes because someone decided to write "ORBC1112" over some part of your data section (in a way that is not visible in the symbolized .elf binaries, only in the final image). This patch seeks to prevent those issues and reduce the need for manual configuration by making the image layout a completely automated part of cbfstool. Since automated placement of the CBFS header means we can no longer hardcode its position into coreboot, this patch takes the existing x86 solution of placing a pointer to the header at the very end of the CBFS-managed section of the ROM and generalizes it to all architectures. This is now even possible with the read-only/read-write split in ChromeOS, since coreboot knows how large that section is from the CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be changed on systems that place other data next to coreboot/CBFS in ROM). Also adds a feature to cbfstool that makes the -B (bootblock file name) argument on image creation optional, since we have recently found valid use cases for CBFS images that are not the first boot medium of the device (instead opened by an earlier bootloader that can already interpret CBFS) and therefore don't really need a bootblock.

2015-04-06New mechanism to define SRAM/memory map with automatic bounds checkingJulius Werner
This patch creates a new mechanism to define the static memory layout (primarily in SRAM) for a given board, superseding the brittle mass of Kconfigs that we were using before. The core part is a memlayout.ld file in the mainboard directory (although boards are expected to just include the SoC default in most cases), which is the primary linker script for all stages (though not rmodules for now). It uses preprocessor macros from <memlayout.h> to form a different valid linker script for all stages while looking like a declarative, boilerplate-free map of memory addresses to the programmer. Linker asserts will automatically guarantee that the defined regions cannot overlap. Stages are defined with a maximum size that will be enforced by the linker. The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date. The mechanism is implemented for all boards in the ARM, ARM64 and MIPS architectures, and should be extended onto all systems using SRAM in the future. The CAR/XIP environment on x86 has very different requirements and the layout is generally not as static, so it will stay like it is and be unaffected by this patch (save for aligning some symbol names for consistency and sharing the new common ramstage linker script include). BUG=None TEST=Booted normally and in recovery mode, checked suspend/resume and the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies with ToT and looked for red flags.
