2019-08-22Add buffer_to/from_fifo32(_prefix) helpersJulius Werner
Many peripheral drivers across different SoCs regularly face the same task of piping a transfer buffer into (or reading it out of) a 32-bit FIFO register. Sometimes it's just one register, sometimes a whole array of registers. Sometimes you actually transfer 4 bytes per register read/write, sometimes only 2 (or even 1). Sometimes writes need to be prefixed with one or two command bytes which makes the actual payload buffer "misaligned" in relation to the FIFO and requires a bunch of tricky bit packing logic to get right. Most of the times transfer lengths are not guaranteed to be divisible by 4, which also requires a bunch of logic to treat the potential unaligned end of the transfer correctly. We have a dozen different implementations of this same pattern across coreboot. This patch introduces a new family of helper functions that aims to solve all these use cases once and for all (*fingers crossed*).

2019-07-26src/device/oprom: Fix bootsplash display code for optionromsJohanna Schander
So far the bootsplash is only correctly rendered if the framebuffer is set up as 1024x768@16. Different resolutions did not show anything, differnent depth resulted in the distorted images. This commit removes this limit by using the actual framebuffer resolutions and combines the code for x86 and yabel. For the moment the bootsplash is still limited to VGA-OptionROM framebuffer init. It was tested in 1280x1024@32 on the wip razer blade stealth using the intel vgabios.

2019-05-15vboot: remove OPROM-related codeJoel Kitching
As of CL:1605641, vboot2 code should be used for setting and checking display init state. Remove all vboot1 OPROM-related code, and use the vboot2 display init code which has already been added in previous commits. coreboot should not be reading vboot NVRAM flags directly. Remove the function vboot_wants_oprom(), and instead rely on display_init_required(), which uses the VBOOT_WD_FLAG_DISPLAY_INIT value stored in vboot_working_data.flags, initialized during verstage. Note that this means in the case of CONFIG_VBOOT=y, the return value of display_init_required() can only be trusted after verstage has been executed. This should not be a problem assuming that all display initialization occurs in ramstage.

2019-04-07device/pci: Rewrite PCI MMCONF with symbol referenceKyösti Mälkki
The effect of pointer aliasing on writes is that any data on CPU registers that has been resolved from (non-const and non-volatile) memory objects has to be discarded and resolved. In other words, the compiler assumes that a pointer that does not have an absolute value at build-time, and is of type 'void *' or 'char *', may write over any memory object. Using a unique datatype for MMIO writes makes the pointer to _not_ qualify for pointer aliasing with any other objects in memory. This avoid constantly resolving the PCI MMCONF address, which is a derived value from a 'struct device *'.

2019-04-02vboot: Change oprom checks to CONFIG_VBOOT, assert OPROM_MATTERSJulius Werner
Skipping display init on normal-mode boot is a vboot feature, not specific to Chrome OS. Fix the code in display_init_required() and pci_dev_init() to check CONFIG_VBOOT rather than CONFIG_CHROMEOS now that the two aren't always the same anymore. Also add a check to guarantee at compile time that CONFIG_VBOOT_OPROM_MATTERS is enabled on all platforms that make a check to this function (when CONFIG_VBOOT is also enabled). The whole display skipping mechanism is based on the oprom_needed NVRAM flag, and skipping display init without enabling the option to tell vboot that it needs to pay attention to that flag would make the whole thing not work right.
