2015-04-13spi: support controllers with limited transfer size capabilitiesVadim Bendebury
Some SPI controllers (like Imgtec Pistachio), have a hard limit on SPI read and write transactions. Limiting transfer size in the wrapper allows to provide the API user with unlimited transfer size transactions. The tranfer size limitation is added to the spi_slave structure, which is set up by the controller driver. The value of zero in this field means 'unlimited transfer size'. It will work with existion drivers, as they all either keep structures in the bss segment, or initialize them to all zeros. This patch addresses the problem for reads only, as coreboot is not expected to require to write long chunks into SPI devices. BRANCH=none BUG=chrome-os-partner:32441, chrome-os-partner:31438 TEST=set transfer size limit to artificially low value (4K) and observed proper operation on both Pistachio and ipq8086: both Storm and Urara booted through romstage and ramstage.

2015-04-13chromeos: Reverse FMAP signature constant to avoid having it in .rodataJulius Werner
Even though coreboot always hardcodes the FMAP offset, the same is not possible for all other tools that manipulate ROM images. Some need to manually find the FMAP by searching for it's magic number (ASCII "__FMAP__"). If we do something like 'memcmp(fmap_buffer, "__FMAP__", ...) in coreboot code, it has the unfortunate side effect that the compiler will output that very same magic number as a constant in the .rodata section to compare against. Other tools may mistake this for the "real" FMAP location and get confused. This patch reverses the constant defined in coreboot and changes the only use of it correspondingly. It is not impossible but extremely unlikely (at the current state of the art) that any compiler would be clever enough to understand this pattern and optimize it back to a straight memcmp() (GCC 4.9 definitely doesn't), so it should solve the problem at least for another few years/decades. BRANCH=veyron BUG=chromium:447051 TEST=Made sure the new binaries actually contain "__PAMF__" in their .rodata. Booted Pinky. Independently corrupted both the first and the last byte of the FMAP signature with a hex editor and confirmed that signature check fails in both cases.

2015-04-13elog: Fix regression that caused elog to omit "System boot" eventJulius Werner
CL:243671 moved the initialization of elog_initialized around, which is now unfortunately so late that the ELOG_TYPE_BOOT event gets omitted because the code believes the log to be broken at that time. Good thing we now have a FAFT test for these things that I had of course been too lazy to run. -.- The real reason for moving that line was to put it after any point in elog_init() that could still error out. The problem is that we might add the "cleared" event before we try to shrink (which can fail and cause an error)... but those two things cannot happen at the same time, so it should be okay to flip them around and mark the elog as initialized in between.

2015-04-13elog: Correct behavior when FMAP section doesn't exist on ChromeOSJulius Werner
The elog driver has a really stupid bug that checks a result which is stored in an unsigned variable for < 0. Surprisingly GCC does not catch this nonsense right now, and I spent an hour trying out different warning options without finding one that doesn't also bring a load of stupid and unavoidable false positives (the biggest offender being -Wtype-limits, which does exactly what we'd want except for flagging things like if ((u8)var >= CONFIG_VAR_MIN) where the VAR_MIN Kconfig may or may not be 0). So, the only thing we can do is fix this one and wait for the next time something like that blows up. -.- Also change some more code to make the behavior more explicit (the old code already intended to work this way since flash_base is statically initialized to 0, never assigned in the error path and checked later in elog_init()... but there was an error message that incorrectly claimed a different fallback behavior, and explicitly assigning the values makes this easier to see). Finally, add another state to the elog_initialized variable to avoid trying to reinitialize a broken eventlog on every event (if it doesn't work the first time, chances are that it won't work later on during the same boot either).

2015-04-10veyron: Change VCC10_LCD_PWREN_H to allowed maximum of 2.5VJulius Werner
LDO7 (VCC10_LCD_PWREN_H) is essentially just a glorified GPIO that turns the real VCC10 regulator on or off. We tried setting it to 3.3V since it matches the VCC33_SYS voltage on the input of that regulator. However, we didn't notice that the LDO only supports going up to 2.5V. This patch changes the voltage to the allowed maximum, which should still work fine as an enable line (and is the same value used by the kernel). This removes an assertion error in the ramstage. Also change the PMIC driver to assert maximum VSEL values based on the LDO, because the lower-voltage ones support one more setting. (LDO3 is actually listed to only go up to 0b1111 in the manual, and has a weird jump from 0b1101 -> 2.2V (skipping over 0b1110) to 0b1111 -> 2.5V. I don't know if that's a documentation error or what they were smoking when they designed that, but we don't need to care for now.)

2015-04-10veyron: Change eMMC enable pin to be pulled (not driven) highDoug Anderson
The eMMC enable pin is in a 3.3V IO domain. Unfortunately the eMMC expects this pin to be 1.8V. The way we were driving this pin would cause the eMMC to pull power through this pin and that was causing current leaks. In future revisions of hardware we should move this pin somewhere more legit. However, in the current hardware we can get things working pretty well by using a pullup to "drive" this pin. This will work in conjunction with the external 100K pullup to give a somewhat reasonable voltage. The eMMC will also not be able to pull much current through this pin, so it can't leak too badly.

This can be filled by: 1) Primary CPU before bringing up secondary CPUs so that the secondary can use register values to initialize MMU-related and other required registers to appropriate values. 2) CPU suspend path to ensure that on resume the values which were saved are restored appropriately. stage_entry.S provides a common path for both normal and resume boot to initialize saved registers. For resume path, it is important to set the secondary entry point for startup since x26 needs to be 1 for enabling MMU and cache. This also ensures that we do not fall into false memory cache errors which caused CPU to fail during normal / resume boot. Thus, we can get rid of the stack cache invalidate for secondary CPUs.

2015-04-10arm64: Add function for reading TCR register at current ELFurquan Shaikh
TCR at EL1 is 64-bit whereas at EL2 and EL3 it is 32-bit. Thus, use 64-bit variables to read / write TCR at current EL. raw_read_tcr_elx will handle it automatically by accepting / returning 32-bit / 64-bit values.

2015-04-10arm64: ensure secondary CPU's stack tops are not in the cacheAaron Durbin
Secondary CPUs were intermittently not coming online as expected. Upon investigation it was found that a cache line needed to be invalidated that corresponded to the top of the stack for the failing CPU. Currently the secondary CPUs come online with caching disabled. However, the code paths are using C and thus the stack it is assigned. The MMU is enabled in C after it's pushed its return path onto the stack that went directly to ram. When the cache line corresponding to its stack is valid in the cache it will hit once the MMU is enabled. That hit will have invalid data w.r.t. the return addresses pushed directly into ram. This is not the best solution as the only way to guarantee we don't hit such a situation is to tightly manage resource usage up until the point of MMU enablement. That can be done in a followup patch. BUG=chrome-os-partner:33962 BRANCH=None TEST=On ryu where secondary CPUs weren't coming online consistently, they now come up.
