2023-01-28util/nvmutil: cmd_swap(): write sequentuallyLeah Rowe
the current code writes part 1 first, and part 0 next, on the disk, due to the way the swap works. with this change, swap still swaps the two parts of the file, on disk, but writes the new file sequentially. this change might speed up i/o on the file system, on HDDs. on SSDs, this change likely makes no difference at all.

2023-01-28util/nvmutil: simplify rhex()Leah Rowe
don't use malloc(). instead, just load random bytes into a uint64_t
2023-01-27util/nvmutil: use gbe[] in word() and setword()Leah Rowe
this will make the code more flexible, if (when) i add changes that allow multiple commands to be used in a single run, on any given number of files

2023-01-27util/nvmutil: optimised disk readsLeah Rowe
only read the required number of bytes, per command
2023-01-27util/nvmutil: optimise cmd_swap()Leah Rowe
On many Lenovo GbE regions (in factory firmware), part 0 is invalid but part 1 is valid. This change means part 1 is checked first. If part 1 is valid, part 0 won't be checked at all (due to how most C compilers optimise). Most people are just going to extract the factory GbE file, modify it and re-insert it into the ROM image, so this causes a nice speedup.
2023-01-27util/nvmutil: optimise rhex() for speedLeah Rowe
don't constantly open/close the file: /dev/urandom only read 12 bytes at a time because of this change, the readFromFile() function now only handles gbe files

2023-01-17util/nvmutil: limit bytes written per commandLeah Rowe
Massive reduction in number of bytes written, if copy/swap commands are not used.

2023-01-17util/nvmutil: only write parts that are modifiedLeah Rowe
Old behaviour: always write both gbe sections. New behaviour: only write back what was changed.

2022-12-31u-boot: Enable USB_EHCI_EXYNOS on peach boardsAlper Nebi Yasak
The USB 2.0 ports on Exynos boards need the relevant driver enabled by USB_EHCI_EXYNOS. This is enabled by default depending on USB_EHCI_HCD. It's already enabled on snow and spring, but apparently not on peach boards, as discovered from other people's attempts to enable it [1][2]. Enable it also on the peach_pi and peach_pit.

2022-12-31u-boot: Enable DM_RESET for veyron boardsAlper Nebi Yasak
The display driver on the veyron boards needs reset drivers, more specifically RESET_ROCKCHIP. This is enabled by default depending on DM_RESET, which an upstream commit enables for veyron_jerry claiming it fixes the display [1]. Enable it also in our configs, but for other veyrons as well.

2022-12-24util/nvmutil: more robust pointer handlingLeah Rowe
i didn't like the previous commits, they felt really hacky running malloc and then changing the pointer directly just rubs me the wrong way fix that
2022-12-23util/nvmutil: optimise cmd_swap() furtherlbmkplaceholder
don't do xor swap. we know gbe2 is always 4KB higher than gbe in memory, so we can just set gbe2 to the value of gbe, and OR the size in bytes of 4KB into gbe2 this is only a marginal speed boost, negligible even, but it's done for the lulz
2022-12-23util/nvmutil: greatly optimise cmd_copy()lbmkplaceholder
similar to the last change by concept. we now write individual 4KB blocks per part 0 and 1, at the end of nvmutil, based on pointer values gbe and gbe2 instead of running memcpy, simply overwrite the pointer this results in less I/O, thus more speed
2022-12-23util/nvmutil: greatly optimise cmd_swap()lbmkplaceholder
instead of XOR-swapping every byte, have pointers to the two parts and *XOR swap the pointers*. at the end of the program execution, when writing, pwrite the two parts into the same file

2022-12-11p2b_ls/p3b_f boards: no payload and no vga initLeah Rowe
The configs were enabling SeaBIOS payload, but this is to be handled by lbmk, not coreboot. Further, they were enabling VGA ROM execution in coreboot, but this should be handled by SeaBIOS. This board should not have a GRUB payload enabled either; this will be checked and fixed if necessary in the next commit.

2022-12-10coreboot: Add qemu_arm64_12mb boardAlper Nebi Yasak
Add a build for QEMU AArch64 virtual machine using U-Boot as payload. Coreboot config is based on the following defconfig: CONFIG_CBFS_SIZE=0x00c00000 CONFIG_BOARD_EMULATION_QEMU_AARCH64=y CONFIG_CONSOLE_CBMEM_BUFFER_SIZE=0x20000 CONFIG_COREBOOT_ROMSIZE_KB_12288=y CONFIG_UART_PCI_ADDR=0x0 The resulting ROM can be booted with a command line like: qemu-system-aarch64 \ -machine virt,secure=on,virtualization=on \ -cpu cortex-a53 -m 1G \ -vga none -display none -serial stdio \ -bios bin/qemu_arm64_12mb/uboot_*.rom However, this is little more than a proof of concept because U-Boot upstream is missing coreboot integration on non-x86 boards, which could have been useful for e.g. a framebuffer.

2022-12-10u-boot: Add qemu_arm64_12mb boardAlper Nebi Yasak
Add a U-Boot payload build for the QEMU AArch64 virtual machine. The config is same as upstream "qemu-arm64" defconfig, but SYS_TEXT_BASE is set to 0x50000000 so that it doesn't conflict with coreboot. QEMU auto-generates and passes a device-tree file to U-Boot at runtime, there's no compile-time canonical version, so there's no need to set REMAKE_ELF or OF_EMBED. It's not immediately obvious if QEMU-specific drivers are available to support display output, but most coreboot integration is unavailable (depends on x86) and entire video subsystem is disabled in the U-Boot upstream defconfig.
