libpayload: Introduce new Kconfig to explicitly allow GPL code There have been leaks of GPL code into libpayload for a while now, for new features or improvements that require third party code with no adequate alternative among BSD-licensed software. It seems silly and counter-productive to keep holding back features and performance improvements from libpayload for a use-case (proprietary payloads) that doesn't even seem to be implemented anywhere to date. Open-source payloads should not need to suffer to appease commercial ones. Instead, this patch introduces a new Kconfig option to explicitly allow inclusion of GPL code. It will use Kconfig dependencies and/or Makefile rules to ensure that no GPL code can end up in the final payload if that option is unset, allowing proprietary payloads to keep working with the existing BSD-licensed feature set. New features and patches (that are sufficiently separate and self-contained to allow guarding through this config option) can choose whether to import GPL code, and need to depend on this option if they do. Also clean up all (known) existing uses of GPL code to depend on the new option, add some recent third-party imports to the LICENSES file, and relicense the selfboot.c files to BSD with permission of the author. BUG=chrome-os-partner:24957 TEST=Compiled Falco and Nyan_Big both with and without the new option, disassembled output binaries to ensure that memcpy() looks as expected.

libpayload: Add remote GDB support This patch adds the ability to attach a GDB host through the UART to a running payload. Libpayload implements a small stub that can parse and respond to the GDB remote protocol and provide the required primitives (reading/writing registers/memory, etc.) to allow GDB to control execution. The goal of this implementation is to be as small and uninvasive as possible. It implements only the minimum amount of primitives required, and relies on GDB's impressive workaround capabilities (such as emulating breakpoints by temporarily replacing instructions) for the more complicated features. This way, a relatively tiny amount of code on the firmware side opens a vast range of capabilities to the user, not just in debugging but also in remote-controlling the firmware to change its behavior (e.g. through GDBs ability to modify variables and call functions). By default, a system with the REMOTEGDB Kconfig will only trap into GDB when executing halt() (including the calls from die_if(), assert(), and exception handlers). In addition, payloads can manually call gdb_enter() if desired. It will print a final "Ready for GDB connection." on the serial, detach the normal serial output driver and wait for the commands that GDB starts sending on attach. Based on original implementation by Gabe Black <gabeblack@chromium.org>. BUG=chrome-os-partner:18390 TEST=Boot a GDB enabled image in recovery mode (or get it to hit a halt()), close your terminal, execute '<toolchain>-gdb --symbols /build/<board>/firmware/depthcharge_gdb/depthcharge.elf --directory ~/trunk/src/third_party/coreboot/payloads/libpayload --directory ~/trunk/src/platform/depthcharge --directory ~/trunk/src/platform/vboot_reference --ex "target remote <cpu_uart_pty>"' and behold the magic. (You can also SIGSTOP your terminal's parent shell and the terminal itself, and SIGCONT them in reverse order after GDB exits. More convenient wrapper tools to do all this automatically coming soon.)

libpayload: Add LZ4 decompression algorithm This patch adds support for the LZ4 decompression algorithm to libpayload. It's what all the cool kids are using for decompression these days and has many interesting advantages over LZMA (and everything else I know of): blazing fast decompression (20(!) times faster than LZMA, twice as fast as LZO on my Cortex-A72), no memory requirements on decompression, and possibly in-place decompression support. It pays for that with a lower compression ratio (about 50% larger compressed size than LZMA, 10% larger than LZO for an ARM64 Linux kernel binary), but the boot time math still works in its favor for our IO speeds. This patch only adds the raw decompression functions for use by external payloads, we can later try integrating them in CBFS. It copies the decompression code itself unmodified from the upstream LZ4 library at github.com/Cyan4973/lz4 which will hopefully make it easy to update. The frame format parsing is reimplemented since the upstream version looks unnecessarily complex and unreadable for our needs. BRANCH=smaug BUG=chrome-os-partner:32184 TEST=With other patches, booted ARM64 kernel that got compressed from 15M to 5.1M and decompresses in 44ms.

libpayload: usb: Support MTK xHCI host controller 1. There is a mis-understanding to calculate the value of TD Size in Normal TRB. For MTK's xHCI controller it defines a number of packets that remain to be transferred for a TD after processing all Max packets in all previous TRBs, that means don't include the current TRB's. 2. To minimize the scheduling effort for synchronous endpoints in xHC, the MTK architecture defines some extra SW scheduling parameters for HW. According to these parameters provided by SW, the xHC can easily decide whether a synchronous endpoint should be scheduled in a specific uFrame. The extra SW scheduling parameters are put into reserved DWs in Slot and Endpoint Context. But in coreboot synchronous transfer can be ignored, so only two fields are set to a default value 1 to support bulk and interrupt transfers, and others are set to zero. 3. For control transfer, it is better to read back doorbell register or add a memory barrier after ringing the doorbell to flush posted write. Otherwise the first command will be aborted on MTK's xHCI controller. 4. Before send commands to a port, the Port Power in PORTSC register should be set to 1 on MTK's xHCI so a hook function of enable_port in generic_hub_ops_t struct is provided.
