2019-07-19src: Make implicit fall throughs explicitJacob Garber
Implicit fall throughs are a perpetual source of bugs and Coverity Scan issues, so let's squash them once and for all. GCC can flag implicit fall throughs using the -Wimplicit-fallthrough warning, and this should ensure no more enter the code base. However, many fall throughs are intentional, and we can use the following comment style to have GCC suppress the warning. switch (x) { case 1: y += 1; /* fall through */ case 2: y += 2; /* fall through - but this time with an explanation */ default: y += 3; } This patch adds comments for all remaining intentional fall throughs, and tweaks some existing fall through comments to fit the syntax that GCC expects.

2019-07-03vboot: Use CONFIG_VBOOT_MIGRATE_WORKING_DATA on all platformsJulius Werner
When we added CONFIG_VBOOT_MIGRATE_WORKING_DATA, the idea was that on some Arm platforms the original working data buffer was in SRAM, which stays accessbile for the whole runtime of the system. There is no reason to migrate it into CBMEM on those platforms because ramstage and the payload could continue to access it in SRAM. Now that we've had a couple of months of experience with this option, we found that most of our Arm platforms have some issue that requires migrating anyway, because BL31 often claims SRAM for itself and makes it inaccessible to the payload. On the remaining platforms, accessing SRAM from the payload is possible but still an issue, because libpayload doesn't have enough memory layout information to set up proper page tables for it, so we're accessing it uncached and at risk of alignment errors. Rather than having to figure out how to map the right SRAM range for every platform in the payload, let's just get rid of the option. memcpy()ing 12KB isn't worth this much hassle.

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.

2018-08-09rk3288: Dig up two more KB of SRAM from under the couch cushionsJulius Werner
RK3288 has always been notoriously low on SRAM, to the point where its boards have less than 100 bytes left in both their bootblock/verstage sections. This becomes a problem every time we try to add a tiny amount of code to common coreboot interfaces that are included in them. This patch manages to add another KB to each, one from the CBMEM console (which now might get cut off a bit, but that's life) and one by moving the TTB_SUBTABLES to PMUSRAM. PMUSRAM is a weird world where write accesses must always be exactly 4 bytes long or they hang the CPU, so we mostly ignore it... but thankfully, page table entries are exactly 4 bytes long and that's the only thing we write to this region, so it works out in this case.

2018-05-22rk3399: Enable bootblock compressionJulius Werner
This patch enables the new bootblock compression feature on RK3399, which requires moving MMU initialization into the decompressor stage and linking the decompressor (rather than the bootblock) into the entry point jumped to by the masked ROM. RK3399's masked ROM seems to be using a bitbang SPI driver to load us (very long pauses between clocking in each byte), with an effective data rate of about 1Mbit. Bootblock loading time (as measured on a SPI analyzer) is reduced by almost 100ms (about a third), while the decompression time is trivial (under 1ms).

2018-04-03spi: Add helper functions for bit-bangingJulius Werner
Sometimes when bringing up a new board it can take a while until you have all the peripheral drivers ready. For those cases it is nice to be able to bitbang certain protocols so that you can already get further in the boot flow while those drivers are still being worked on. We already have this support for I2C, but it would be nice to have something for SPI as well, since without SPI you're not going to boot very far. This patch adds a couple of helper functions that platforms can use to implement bit-banging SPI with minimal effort. It also adds a proof of concept implementation using the RK3399.

The Rockchip UARTs are tied directly to the 24MHz oscillator and are thus clocked with exactly 24MHz. The reasons why our code instead uses some 23.xxMHz value have long been lost in time. For the current shared 8250 implementation, the baud rate divisor for 115200 would be the same. Correcting this does make the information in the coreboot table more accurate and help payloads chose a better divisor, though.

It seems that the BootROM on the RK3399 overwrites some of the earlier parts of SRAM, including the PRERAM_CBMEM_CONSOLE area. Now that we have a persistent CBMEM console we want that area to survive in case of an early (pre-CBMEM) reboot, so shuffle the layout around a bit to move it further back.

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.

I've recently added an assertion to ensure that the effective I2C frequency on Rockchip SoCs is not too far off the 400KHz target due to divisor rounding errors. A 10KHz margin worked fine for RK3399, but it turns out that RK3288 actually only ever hit 387KHz since its I2C clocks are based off the already pretty low 75MHz PCLKs. While we could probably change the PCLKs to make this closer, that seems like a too intrusive change for something that has already worked just fine for years, so just loosen the restriction a little more instead.

2016-11-22spi: Clean up SPI flash driver interfaceFurquan Shaikh
RW flag was added to spi_slave structure to get around a requirement on some AMD flash controllers that need to group together all spi volatile operations (write/erase). This rw flag is not a property or attribute of the SPI slave or controller. Thus, instead of saving it in spi_slave structure, clean up the SPI flash driver interface. This allows chipsets/mainboards (that require volatile operations to be grouped) to indicate beginning and end of such grouped operations. New user APIs are added to allow users to perform probe, read, write, erase, volatile group begin and end operations. Callbacks defined in spi_flash structure are expected to be used only by the SPI flash driver. Any chipset that requires grouping of volatile operations can select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and define callbacks for chipset_volatile_group_{begin,end}. spi_claim_bus/spi_release_bus calls have been removed from the SPI flash chip drivers which end up calling do_spi_flash_cmd since it already has required calls for claiming and releasing SPI bus before performing a read/write operation. BUG=None BRANCH=None TEST=Compiles successfully.
