2015-01-09libpayload: Add remote GDB supportJulius Werner
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.)

2014-09-29libpayload: Build libpayload with debugging info turned up all the way.Gabe Black
Pass -ggdb3 to the compiler when building libpayload, -ggdb so that it uses "the most expressive format available", and 3 so that the debugging level is set to 3, the highest value currently supported. The debugging information can be stripped by the payload consuming the library, and will definitely be stripped by cbfstool when installing that payload into an image.

2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

The tegra124 bootblock will ultimately need to be ARMv4, but until we have some ARMv4 code to switch over to we can leave it set to ARMv7.

2014-08-05libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig.Gabe Black
When libpayload header files are included in the payload itself, it's possible that the payloads config settings will conflict with the ones in libpayload. It's also possible for the libpayload config settings to conflict with the payloads. To avoid that, the libpayload config settings have _LP_ (for libpayload) added to them. The symbols themselves as defined in the Config.in files are still the same, but the prefix added to them is now CONFIG_LP_ instead of just CONFIG_.

2013-03-18libpayload: Fix the config file dependency in the Makefile templateGabe Black
The template had a dependency on config.h which was correct for coreboot, where this build system originally came from, but not for libpayload which uses the differently named libpayload-config.h, presumably to avoid colliding with a config.h used by the actual payload. Because libpayload-config.h is now effectively a dependency of everything, it doesn't have to be added piecemeal in Makefile.inc.
