2020-09-26payloads/external: add support for BOOTBOOT payloadZoltan Baldaszti
BOOTBOOT is a multi-platform, architecture agnostic boot protocol. The protocol describes how to boot an ELF64 or PE32+ executable inside an initial ram disk image into clean 64 bit mode. This version uses libpayload to do that. Depending on the lib's configuration, initrd can be in ROM as a cbfs file or a Flashmap partition; on disk a GPT partition or a file on a FAT formatted ESP partition.

2020-09-18libpayload: cbgfx: Fix 'equals' counter for Lanczos resamplingYu-Ping Wu
The current initialization of the 'equals' counter is incorrect, so that when 'equals >= SSZ * SSZ', the pixels in the sample array might not be all the same, leading to a wrong pixel value being set in the framebuffer. The 'equals' counter stores the number of latest pixels that were exactly equal. Within the for loop of 'ox', the sample array is updated in a column-based order, and the 'equals' counter is updated accordingly. However, the 'equals' counter is initialized in a row-based order, which causes it to be set too large than it should be. Consider the example where sample[sx][sy] are initially: [X X X A A A] // sy = 0 [X X X B B B] [X X X B B B] [X X X B B B] [X X X B B B] [X X X B B B] // sy = SSZ Then, the correct implementation will initialize 'equals' to be 15, with last_equal being B. Suppose all of the remaining pixels are B. Then, at the end of the 'while (fpfloor(ixfp) > ix)' loop when ix = 4, or equivalently after 4 more columns of sample are updated, 'equals' will be 15 + 6 * 4 = 39, which is greater than SSZ * SSZ = 36, but we can see there are still 2 A's in the sample: [B B B B A A] [B B B B B B] [B B B B B B] [B B B B B B] [B B B B B B] [B B B B B B] Therefore, we must also initialize the 'equals' counter in a column-based order.

2020-09-13libpayload: malloc: Fix realloc for overlapping buffersYu-Ping Wu
The current realloc() works by freeing the origin buffer, allocating a new one, and copying the data over. It's true that free() won't touch the actual memory. However, the alloc() following it will potentially modify the memory that belongs to the old buffer in order to create a new free block (right after the newly allocated block). This causes 8 bytes (HDRSIZE) to be overwritten before being copied to the new buffer. To fix the problem, we must create the header of the new free block after the data is copied. In this patch, the content of alloc() is split into two functions: 1. find_free_block(): Find a free block with large enough size, without touching the memory 2. use_block(): Update the header of the newly allocated block, and create the header of the new free block right after it Then, inside realloc(), call memmove() call right after find_free_block() while before use_block().

2020-08-24libpayload: memmove: Don't make expectations of architecture memcpyJulius Werner
default_memmove() calls memcpy() when (src > dst). This is safe for the default_memcpy() implementation, but just calling memcpy() may invoke an architecture-specific implementation. Architectures are free to implement memcpy() however they want and may assume that buffers don't overlap in either direction. So while this happens to work for all current architecture implementations of memcpy(), it's safer not to rely on that and only rely on the known implementation of default_memcpy() for the forwards-overlapping case.

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().

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().

EDK II itself will not use any code/feature from submodules in above submodules. So using '--recursive' adds a dependency on being able to reach servers we do not actually want any code from, as well as needlessly downloading code we will not use."

2020-07-09libpayload: cbgfx: Replace bilinear resampling with LanczosJulius Werner
This patch improves the image resampling (scaling) code in CBGFX to use the Lanczos algorithm that is widely considered the "best" resampling algorithm (e.g. also the first choice in Python's PIL library). It is of course much more elaborate and therefore slower than bilinear resampling, but a lot of the difference can be made up with optimizations, and the resulting code was found to still produce acceptable speeds for existing Chrome OS UI use cases (on an Arm Cortex-A55 device, time to scale an image to 1101x593 went from ~88ms to ~275ms, a little over 3x slowdown). Nevertheless, if this should be too slow for anyone there's also an option to tune it down a little, but still much better than bilinear (same operation was ~170ms with this).

2020-07-09libpayload: Add simple 32.32 fixed-point math APIJulius Werner
struct fraction is slooooooooooow. This patch adds a simple 64-bit (32-bits integral, 32-bits fractional) fixed-point math API that is *much* faster (observed roughly 5x speed-up) when doing intensive graphics operations. It is optimized for speed over accuracy so some operations may lose a bit more precision than expected, but overall it's still plenty of bits for most use cases. Also includes support for basic trigonometric functions with a small lookup table.

2020-07-06libpayload: cbgfx: Fix add_fractions() overflow reductionJulius Werner
log2(1) is 0 and log2(0) is -1. If we have the int64_t 0xffffffff then log2(0xffffffff >> 31) = log2(0x1) = 0, so the current reduction code would not shift. That's a bad idea, though, since 0xffffffff when interpreted as an int32_t would become a negative number. We need to always shift one more than the current code does to get a safe reduction. This also means we can get rid of another compare/branch since -1 is the smallest result log2() can return, so the shift can no longer go negative now.
