When forcing JTAG\nboot, this device disables most communication peripherals, including\nserial and ethernet devices. This appears to be fixed in later\ngeneration devices, but we are stuck with it for now. Semihosting\nprovides an easy way to run a few console commands.\n\nFuture work could include modifying one of the reset handlers to catch\nsemihosting calls not handled by a debugger. This would allow using the\nsame U-Boot when booting from JTAG and when booting normally.\nAdditionally, we could use puts in more places. DM serial is especially\nslow with semihisting because all we have is putc.\n\nThe patches in this series are organized as follows:\n0-3: rST conversions and other documentation updates\n4-8: Semihosting cleanups\n9-13: Filesystem support (including SPL boot device)\n14-15: Serial support\n16: Documentation update\n17: JTAG boot support for LS1046A\n\nPatch 17 depends on [1].\n\n[1] https://lore.kernel.org/u-boot/20220222183840.1355337-2-sean.anderson@seco.com/\n\n\nSean Anderson (17):\n doc: Convert semihosting readme to rST\n nxp: ls1046ardb: Convert README to rST\n doc: ls1046ardb: Expand boot mode section\n arm: smh: Add semihosting entry to MAINTAINERS\n arm: smh: Export semihosting functions\n arm: smh: Use numeric modes for smh_open\n arm: smh: Return errno on error\n arm: smh: Document functions in header\n arm: smh: Add some file manipulation commands\n spl: Add semihosting boot method\n fs: Add semihosting filesystem\n cmd: fdt: Use start/size for chosen instead of start/end\n arm: smh: Remove smhload command\n arm: smh: Add some functions for working with the host console\n serial: Add semihosting driver\n doc: smh: Update semihosting documentation\n ls1046ardb: Add support for JTAG boot\n\n MAINTAINERS | 4 +\n arch/arm/Kconfig | 25 ++-\n arch/arm/cpu/armv8/fsl-layerscape/spl.c | 2 +\n arch/arm/include/asm/spl.h | 1 +\n arch/arm/lib/semihosting.c | 209 ++++++++++--------------\n board/freescale/ls1046ardb/MAINTAINERS | 1 +\n board/freescale/ls1046ardb/README | 76 ---------\n cmd/fdt.c | 6 +-\n common/spl/Makefile | 1 +\n common/spl/spl_semihosting.c | 71 ++++++++\n configs/vexpress_aemv8a_semi_defconfig | 2 +-\n disk/part.c | 4 +-\n doc/README.semihosting | 38 -----\n doc/board/nxp/index.rst | 1 +\n doc/board/nxp/ls1046ardb.rst | 182 +++++++++++++++++++++\n doc/usage/index.rst | 1 +\n doc/usage/semihosting.rst | 51 ++++++\n drivers/serial/Kconfig | 22 +++\n drivers/serial/Makefile | 1 +\n drivers/serial/serial.c | 2 +\n drivers/serial/serial_semihosting.c | 108 ++++++++++++\n fs/Makefile | 1 +\n fs/fs.c | 20 +++\n fs/semihostingfs.c | 115 +++++++++++++\n include/configs/ls1046ardb.h | 2 +\n include/fs.h | 1 +\n include/semihosting.h | 108 ++++++++++++\n include/semihostingfs.h | 21 +++\n 28 files changed, 832 insertions(+), 244 deletions(-)\n delete mode 100644 board/freescale/ls1046ardb/README\n create mode 100644 common/spl/spl_semihosting.c\n delete mode 100644 doc/README.semihosting\n create mode 100644 doc/board/nxp/ls1046ardb.rst\n create mode 100644 doc/usage/semihosting.rst\n create mode 100644 drivers/serial/serial_semihosting.c\n create mode 100644 fs/semihostingfs.c\n create mode 100644 include/semihosting.h\n create mode 100644 include/semihostingfs.h" }
