This series includes a number of base driver model enhancements, mostly targeted at pre-relocation and to enable buses to be easily implemented.
With the device tree, child nodes for buses can now be scanned to create child devices, and bus-related information about each child can be stored. Children can be numbered as a core driver model feature in U-Boot (e.g. SPI bus 0 chip select 3). Driver model now supports operation prior to relocation, assuming a suitable malloc() implementation is available. Several changes are added to permit driver model to be available early after relocation, since we are unable to access any device until driver model is ready. This series is available at u-boot-dm.git branch 'working'. Changes in v2: - Remove change to board/rbc823/kbd.c, since it has been deleted - Reformat commit message slightly - Remove changes to deleted board/netphone/phone_console.c board/rbc823/kbd.c - Rename struct device to struct udevice - Update test output in doc/driver-model/README.txt - Minor reword to comment for dm_init_and_scan() - Return -ENODEV instead of -1 on error - Improve wording in commit message - Improve wording in commit message - Expand series to include all driver-model-required changes Simon Glass (29): dm: gpio: Don't use the driver model uclass for SPL dm: Use an explicit expect value in core tests stdio: Remove redundant code around stdio_register() calls stdio: Pass device pointer to stdio methods dm: Make sure that the root device is probed dm: Provide a way to shut down driver model sandbox: Remove all drivers before exit dm: Allow drivers to be marked 'before relocation' dm: Support driver model prior to relocation stdio: Provide functions to add/remove devices using stdio_dev console: Remove vprintf() optimisation for sandbox Add a flag indicating when the serial console is ready dm: Move uclass error checking/probing into a function fdt: Add a function to get the alias sequence of a node dm: Move device display into its own function dm: Avoid activating devices in 'dm uclass' command dm: Introduce device sequence numbering dm: Display the sequence number for each device dm: Allow a device to be found by its FDT offset dm: Avoid accessing uclasses before they are ready fdt: Add a function to get the node offset of an alias dm: Tidy up some header file comments dm: Provide a function to scan child FDT nodes dm: Add functions to access a device's children dm: Introduce per-child data for devices dm: Add child_pre_probe() and child_post_remove() methods dm: Improve errors and warnings in lists_bind_fdt() dm: Add dm_scan_other() to locate board-specific devices dm: Give the demo uclass a name arch/blackfin/cpu/jtag-console.c | 10 +- arch/powerpc/cpu/mpc512x/serial.c | 10 +- arch/powerpc/cpu/mpc8xx/video.c | 6 +- arch/sandbox/cpu/cpu.c | 4 + arch/x86/lib/video.c | 8 +- board/bf527-ezkit/video.c | 10 -- board/bf548-ezkit/video.c | 10 -- board/cm-bf548/video.c | 10 -- board/mpl/common/kbd.c | 6 +- board/mpl/common/kbd.h | 6 +- board/mpl/pati/pati.c | 8 +- board/nokia/rx51/rx51.c | 6 +- common/board_f.c | 16 +++ common/board_r.c | 25 +--- common/cmd_log.c | 11 +- common/console.c | 24 ++-- common/lcd.c | 14 ++- common/stdio.c | 66 ++++++++--- common/usb_kbd.c | 6 +- doc/driver-model/README.txt | 216 +++++++++++++++++++++++++++++++--- drivers/core/device.c | 169 +++++++++++++++++++++++++- drivers/core/lists.c | 22 +++- drivers/core/root.c | 79 ++++++++++--- drivers/core/uclass.c | 135 ++++++++++++++++++++- drivers/demo/demo-uclass.c | 1 + drivers/gpio/Makefile | 2 + drivers/input/cros_ec_keyb.c | 6 +- drivers/input/i8042.c | 4 +- drivers/input/keyboard.c | 6 +- drivers/input/tegra-kbc.c | 6 +- drivers/misc/cbmem_console.c | 6 +- drivers/net/netconsole.c | 10 +- drivers/serial/serial.c | 55 ++++++++- drivers/serial/usbtty.c | 8 +- drivers/video/cfb_console.c | 8 +- include/asm-generic/global_data.h | 4 +- include/common.h | 5 + include/configs/ELPPC.h | 4 +- include/configs/MHPC.h | 4 +- include/configs/jadecpu.h | 4 +- include/configs/nokia_rx51.h | 5 +- include/dm/device-internal.h | 6 +- include/dm/device.h | 120 ++++++++++++++++++- include/dm/lists.h | 2 +- include/dm/platdata.h | 10 +- include/dm/root.h | 61 +++++++++- include/dm/test.h | 22 ++++ include/dm/uclass-id.h | 3 +- include/dm/uclass-internal.h | 23 ++++ include/dm/uclass.h | 49 +++++++- include/fdtdec.h | 29 +++++ include/i8042.h | 6 +- include/stdio_dev.h | 17 ++- include/video.h | 8 +- lib/fdtdec.c | 61 ++++++++++ test/dm/Makefile | 1 + test/dm/bus.c | 242 ++++++++++++++++++++++++++++++++++++++ test/dm/cmd_dm.c | 35 ++++-- test/dm/core.c | 64 ++++++++-- test/dm/test-driver.c | 11 ++ test/dm/test-fdt.c | 164 ++++++++++++++++++++++---- test/dm/test-main.c | 4 +- test/dm/test.dts | 43 ++++++- 63 files changed, 1714 insertions(+), 282 deletions(-) create mode 100644 test/dm/bus.c -- 2.0.0.526.g5318336 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
