2020-08-24libpayload: Cache physical location of CBMEM entriesNico Huber
In the presence of self-relocating payloads, it's safer to keep physical addresses in `libsysinfo`. This updates all the references to CBMEM entries that are not consumed inside libpayload code.

2020-08-24libpayload: Cache copy of `cb_framebuffer` structNico Huber
Our AArch64 code supports dynamic framebuffer allocation which makes it necessary to change the framebuffer information during runtime. Having a pointer inside `libsysinfo` made a mess of it as the pointer would either refer to the original struct inside the coreboot table or to a new struct inside payload space. The latter would be unaffected by a relocation of the payload. Instead of the pointer, we'll always keep a copy of the whole struct, which can be altered on demand without affecting the coreboot table. To align the `video/graphics` driver with the console driver, we also replace `fbaddr` with a macro `FB` that calls phys_to_virt().

2020-08-24libpayload: Cache physical cbmem console addressNico Huber
Same as with other consoles and drivers that cache an address outside the payload (e.g. video/corebootfb), we should store the physical address, so we can derive the virtual address on demand. This makes it save to use the address across relocations. As a first step in migrating `libsysinfo` to `uintptr_t`, we also switch to the physical address there. Fixes the default build of FILO, tested with Qemu/i440FX and Qemu/Q35.

2020-07-23libpayload: cbgfx: Add draw_line()Yu-Ping Wu
Add a function draw_line() to draw either a horizontal or vertical line segment. Theoretically a horizontal line can also be drawn by calling draw_rounded_box() with dim_rel.x being the line length and dim_rel.y being the line width. However, due to the truncation in integer division when converting relative coordinates to absolute ones, this will potentially produce inconsistent line widths, depending on the value of pos_rel.y. It is guaranteed that draw_line() will produce consistent line widths, regardless of the position of the line. Also, when the thickness argument is zero, this function is able to draw a line with 1-pixel width, which is not achievable by draw_rounded_box().

struct fraction is slooooooooooow.

It replaces the existing mmu_disable() implementation with the assembly version from coreboot which handles certain edge cases better (see CB:27238 for details).

2019-08-22libpayload: usbmsc: Factor out usb_msc_force_init() functionJulius Werner
We're planning to have a use case with a custom USB device that implements the USB mass storage protocol on its bulk endpoints, but does not have the normal MSC class/protocol interface descriptors and does not support class-specific control requests (Get Max LUN and Bulk-Only Reset). We'd like to identify/enumerate the device via usb_generic_create() in our payload but then reuse all the normal MSC driver code. In order to make that possible, this patch factors a new usb_msc_force_init() function out of usb_msc_init() which will initialize an MSC device without checking its descriptors. It also adds some "quirks" flags that allow devices registered this way to customize behavior of the MSC stack.

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*).

2019-04-04Make common macros double-evaluation safeJulius Werner
I just got hit by a double-evaluation bug again, it's time to attempt to fix this once more. Unfortunately there are several issues that don't make this easy: - bitfield variables don't support typeof() - local macro variables that shadow others trigger -Werror=shadow - sign warnings with integer literal and unsigned var in typeof-MIN() - ({ statement expressions }) can not be used outside functions - romcc doesn't support any of the fancy GCC/clang extensions This patch tries to address all of them as far as possible with macro magic. We don't have the technology to solve the bitfield and non-function context issues yet (__builtin_choose_expr() still throws a "no statement expression outside a function" error if it's only in the branch that's not chosen, unfortunately), so we'll have to provide alternative macros for use in those cases (and we'll avoid making __ALIGN_MASK() double-evaluation safe for now, since it would be annoying to do that there and having an alignment mask with side effects seems very unlikely). romcc can continue using unsafe versions since we're hopefully not writing a lot of new code for it. Sign warnings can be avoided in literal/variable comparisons by always using the type of the variable there. Shadowing is avoided by picking very explicit local variable names and using a special __COUNTER__ solution for MIN() and MAX() (the only ones of these you're likely to nest). Also add DIV_ROUND_UP() to libpayload since it's a generally quite useful thing to have.

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.

Due to greater complexity of FIT it is not converted to simple ELF format. Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'. The payload is included as is, with no special header. The code can determine the type at runtime using the CBFS_TYPE field. Support for parsing FIT payloads in coreboot is added in a follow on commit. Compression of FIT payloads is not supported, as the FIT sections might be compressed itself. Starting at this point a CBFS payload/ can be either of type FIT or SELF. Tested on Cavium SoC.

This patch adds functionality to compile a C data structure into a raw binary file, add it to CBFS and allow coreboot to load it at runtime. This is useful in all cases where we need to be able to have several larger data sets available in an image, but will only require a small subset of them at boot (a classic example would be DRAM parameters) or only require it in certain boot modes. This allows us to load less data from flash and increase boot speed compared to solutions that compile all data sets into a stage. Each structure has to be defined in a separate .c file which contains no functions and only a single global variable. The data type must be serialization safe (composed of only fixed-width types, paying attention to padding). It must be added to CBFS in a Makefile with the 'struct' file processor.
