At present sandbox only supports a basic set of features. To help address this, a recent series added SPI and SPI flash support; this series expands the coverage further. Firstly SDL is used to provide LCD and audio support. Sandbox gains its own LCD driver which can display images, host a command line, etc. The audio support is basic and needs additional work, but it is a starting point. SDL also provides a keyboard emulation (using the Chrome OS EC code as a base). Secondly a TPM emulation is added. This does not include all features (the implementation is quite simplistic) but it is enough to do basic secure boot operations. Finally, various pieces of useful infrastructure are added, including: - loading and saving of the emulated SDRAM to permit test runs to carry over state - loading and saving of general sandbox state (for example a driver can save its stage and reload it on the next run) - support for using bootm to load a kernel - providing a device tree for use by sandbox - a means to jump to another U-Boot while preserving state (useful for test environments which want to run a series of tests with script-selectable state) Major functions which still remain without sandbox support are I2C, networking and USB. Note: Much of this series was sent out in November. Due to problems with the LCD side it was not ready for the last release, although about a dozen patches from the series were applied. I have rebased and tidied things up. U-Boot now starts by default without the LCD visible since for much sandbox testing we don't want the LCD. The Chrome OS EC code has been updated and tidied up and full keyboard support is now present in the LCD window. Changes in v2: - Add new patch to adjust #ifdef position in cros_ec - Add new patch to sync with latest Chrome OS EC version - Add new patches to bring in protocol v3 support - Rebase to master - Update series to take account of patches now merges from original series Randall Spangler (2): cros_ec: Clean up multiple EC protocol support cros_ec: spi: Add support for EC protocol version 3 Simon Glass (27): Use a const pointer for map_to_sysmem() sandbox: Increase memory size to 32MB sandbox: Build a device tree file for sandbox sandbox: Use os functions to read host device tree sandbox: dts: Add display and keyboard to sandbox cros_ec: Add an enum for the number of flash regions cros_ec: Add a function for reading a flash map entry cros_ec: Add a function for decoding the Chrome OS EC flashmap cros_ec: Support systems with no EC interrupt cros_ec: Move #ifdef to permit flash region access cros_ec: Sync up with latest Chrome OS EC version cros_ec: Add base support for protocol v3 cros_ec: Correct comparison between signed and unsigned numbers cros_ec: sandbox: Add Chrome OS EC emulation sandbox: Plumb in Chrome OS EC emulation cros_ec: Implement I2C pass-through sandbox: Add os_jump_to_image() to run another executable sandbox: Add -j option to indicate a jump from a previous U-Boot sandbox: Add SDL library for LCD, keyboard, audio sandbox: Add a simple sound driver sandbox: Add LCD driver sound: Move Samsung-specific code into its own file sandbox: Deal with conflicting getenv() for SDL sandbox: Allow Ctrl-C to work in sandbox sandbox: Add options to clean up temporary files sandbox: Add implementation of spi_setup_slave_fdt() sandbox: config: Enable cros_ec emulation and related items Vadim Bendebury (2): cros_ec: Move EC interface into common library cros_ec: Drop old EC version support from EC driver Makefile | 3 +- arch/sandbox/config.mk | 5 + arch/sandbox/cpu/Makefile | 3 + arch/sandbox/cpu/cpu.c | 2 +- arch/sandbox/cpu/os.c | 108 ++++- arch/sandbox/cpu/sdl.c | 341 ++++++++++++++ arch/sandbox/cpu/start.c | 60 +++ arch/sandbox/cpu/state.c | 6 +- arch/sandbox/dts/Makefile | 11 + arch/sandbox/dts/sandbox.dts | 125 ++++++ arch/sandbox/include/asm/arch-sandbox/sound.h | 14 + arch/sandbox/include/asm/sdl.h | 118 +++++ arch/sandbox/include/asm/state.h | 29 +- arch/sandbox/include/asm/u-boot-sandbox.h | 3 + board/samsung/common/board.c | 29 +- board/samsung/smdk5250/exynos5-dt.c | 1 - board/sandbox/sandbox/sandbox.c | 49 ++- common/Makefile | 1 + common/board_f.c | 48 +- common/cros_ec.c | 44 ++ common/lcd.c | 21 +- disk/part.c | 17 - doc/device-tree-bindings/video/sandbox-fb.txt | 13 + drivers/input/cros_ec_keyb.c | 34 +- drivers/misc/Makefile | 1 + drivers/misc/cros_ec.c | 611 +++++++++++++++++++++++--- drivers/misc/cros_ec_i2c.c | 64 ++- drivers/misc/cros_ec_lpc.c | 80 +--- drivers/misc/cros_ec_sandbox.c | 559 +++++++++++++++++++++++ drivers/misc/cros_ec_spi.c | 30 ++ drivers/serial/sandbox.c | 10 +- drivers/sound/Makefile | 4 +- drivers/sound/sandbox.c | 23 + drivers/sound/sound-i2s.c | 208 +++++++++ drivers/sound/sound.c | 221 +--------- drivers/spi/sandbox_spi.c | 13 + drivers/video/Makefile | 1 + drivers/video/sandbox_sdl.c | 79 ++++ include/common.h | 6 + include/configs/exynos5250-dt.h | 1 + include/configs/sandbox.h | 41 +- include/cros_ec.h | 94 +++- include/cros_ec_message.h | 2 +- include/ec_commands.h | 348 +++++++++++++-- include/fdtdec.h | 20 + include/lcd.h | 3 + include/os.h | 27 +- include/sound.h | 9 + lib/fdtdec.c | 26 ++ 49 files changed, 3032 insertions(+), 534 deletions(-) create mode 100644 arch/sandbox/cpu/sdl.c create mode 100644 arch/sandbox/dts/Makefile create mode 100644 arch/sandbox/dts/sandbox.dts create mode 100644 arch/sandbox/include/asm/arch-sandbox/sound.h create mode 100644 arch/sandbox/include/asm/sdl.h create mode 100644 common/cros_ec.c create mode 100644 doc/device-tree-bindings/video/sandbox-fb.txt create mode 100644 drivers/misc/cros_ec_sandbox.c create mode 100644 drivers/sound/sandbox.c create mode 100644 drivers/sound/sound-i2s.c create mode 100644 drivers/video/sandbox_sdl.c -- 1.9.0.279.gdc9e3eb -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
