2019-03-26libpayload: strtoull: Fix edge case bug with *endptrJulius Werner
strtoull() can optionally take a second pointer as an out-parameter that will be adjusted to point to the end of the parsed string. This works almost right, but misses two important edge cases: firstly,when the parsed string is "0", the function will interpret the leading '0' as an octal prefix, so that the first actually parsed digit is already the terminating '\0' byte. This will cause the function to early abort, which still (correctly) returns 0 but doesn't adjust *endptr. The early abort is pointless anyway -- the only other thing the function does is run a for-loop whose condition is the exact inverse (so it's guaranteed to run zero iterations in this case) and then adjust *endptr (which we want). So just take it out. This also technically corrects the behavior of *endptr for a completely invalid string, since the strtoull man page says > If there were no digits at all, strtoul() stores the original value of > nptr in *endptr (and returns 0). The second issue occurs when the parsed string is "0x" without another valid digit behind it. In this case, we will still jump over the 0x prefix so that *endptr is set to the first byte after that. The correct interpretation in this case is that there is no 0x prefix, and instead a valid 0 digit with the 'x' being invalid garbage at the end. By not skipping the prefix unless there's at least one valid digit after it, we get the correct behavior of *endptr pointing to the 'x'.

When updating firmware, we may need to preserve some sections like VPD, calibration data, ... etc. The logic can be hard-coded in updater as a list of known names, but a better solution is to have that directly declared inside FMAP area flags.

2019-03-02libpayload: keyboard: Add option to ignore failures during initDuncan Laurie
If keys are pressed at boot some keyboard controllers will not properly respond with an ACK to commands, which results in the keyboard_init function aborting before it adds the keyboard to the input device list. This same keyboard controller will manage to properly return keyboard data when keys are pressed later, so it is possible for it to be functional in the payload even if it does not respond properly to every command during initialization. In order to allow payloads to use the keyboard when this happens a new Kconfig option is added to ignore the keyboard ACK response and always add the keyboard to the input device list. This option is disabled by default and must be enabled by the specific boards that need it. BUG=b:126633269 TEST=boot on device with this controller and press keys during boot and see that the keyboard is still functional in the payload.

This patch reworks the arm64 exception handling to be more similar to how it works on arm32. This includes a bunch of features like actually saving and restoring more exception state in the exception_state structure and supporting the same sort of partial reentrancy that is useful for GDB. Since there's no instruction to directly load into or store out of SP on arm64, we can't do quite the same thing where we use that to read an exception_state_ptr variable right after exception entry when no other register is available. But we can do something very similar by (ab-)using the "high" stack pointer (SP_EL2) as a pointer to the exception_state struct and providing a function to change it.

This patch adds the new, faster architectural register accessors to libpayload that were already added to coreboot in CB:27881. It also hardcodes the assumption that coreboot payloads run at EL2, which has already been hardcoded in coreboot with CB:27880 (see rationale there). This means we can drop all the read_current/write_current stuff which added a lot of unnecessary helpers to check the current exception level. This patch breaks payloads that used read_current/write_current accessors, but it seems unlikely that many payloads deal with this stuff anyway, and it should be a trivial fix (just replace them with the respective _el2 versions). Also add accessors for a couple of more registers that are required to enable debug mode while I'm here.

This is just the bare minimum required to initialize the APIC. I only support xAPIC and chose not to support x2APIC. We can add that functionality later when it's required. I also made the exception dispatcher call apic_eoi so that the callbacks won't forget to call it. BUG=b:109749762 TEST=Booted grunt and verified that depthcharge continued to function and that linux booted correctly. Also verified GDB still works.

2018-09-10libpayload/x86/exception: Add ability to handle user defined interruptsRaul E Rangel
I need to setup the APIC timer to fire interrupts. I would like to reuse the existing interrupt table. So I extended it to support user defined interrupts. I just added all 255 vectors so there wouldn't need to be any additional build time configuration. I'm going to deprecate exception_install_hook and remove it in a follow up. It will be replaced with set_interrupt_handler. This way the exception lookup does not have to manage a list of callbacks, or have to worry about the order they are processed. BUG=b:109749762 TEST=Wrote an interrupt handler and fired an APIC timer interrupt and verified that vector 32 was returned.

2018-08-14cbmem: rename vdat to chromeos_acpiJoel Kitching
There is a confusingly named section in cbmem called vdat. This section holds a data structure called chromeos_acpi_t, which exposes some system information to the Chrome OS userland utility crossystem. Within the chromeos_acpi_t structure, there is a member called vdat. This (currently) holds a VbSharedDataHeader. Rename the outer vdat to chromeos_acpi to make its purpose clear, and prevent the bizarreness of being able to access vdat->vdat. Additionally, disallow external references to the chromeos_acpi data structure in gnvs.c.
