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.

2019-05-06Fix code that would trip -Wtype-limitsJulius Werner
This patch fixes up all code that would throw a -Wtype-limits warning. This sometimes involves eliminating unnecessary checks, adding a few odd but harmless casts or just pragma'ing out the warning for a whole file -- I tried to find the path of least resistance. I think the overall benefit of the warning outweighs the occasional weirdness.

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).

The <gpio.h> API is supposed to include a gpio_set() function that just toggles the state of a GPIO already configured as an output, even though we rarely need it since gpio_output() can already be used to initialze a GPIO to a default value while configuring it as an output. This function was forgotten on Rockchip, so this patch adds it now.

2018-02-02rockchip: Correct UART reference clock valueJulius Werner
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.

2018-01-10soc/rockchip/rk3399: Ensure full eDP init sequenceEge Mihmanli
This patch fixes 2 edp display issues: 1. When rk_edp_prepare fails >3 times, edp_init isn't run because while-condition is not satisfied. Then, only a partial init sequence is ran. This causes all aux transactions to fail. 2. If rk_edp_prepare never succeeds, coreboot never leaves link training stage due to infinite loop. Boot process is stuck. TEST=Boot past eDP initialization stage and make sure AP logs don't have show aux transaction fails.

2017-12-11google/gru: Stop mucking with unused I2S0 pins in codec configJulius Werner
Due to a schematic error, our code was written to configure more I2S0 pins than are actually used. We're also pinmuxing the whole bank of pins over to the I2S controller even though we don't need them all. Restrict the GPIO initialization and pinmuxing to the pins we really need so the other ones can be correctly used as SKU ID pins on Scarlet. Also, move the "audio" IO voltage domain selection to the other such selections in the bootblock, since that covers two whole banks of GPIOs and there's no guarantee that they're all used for audio (and thus not needed before ramstage). BUG=b:69373077 TEST=Booted Scarlet, confirmed correct SKU ID (7) was detected on rev2.
